Everest Region Trekking: The Complete Khumbu Valley Guide for 2025

The Everest region—known locally as the Khumbu—is where Himalayan trekking began and where it reaches its most iconic expression. Home to four of the world's six tallest peaks, centuries-old Sherpa monasteries, and the legendary Everest Base Camp trail, this region draws over 50,000 trekkers annually for good reason.

But the Khumbu offers far more than the classic Base Camp route. From the turquoise glacial lakes of Gokyo to the demanding triple-pass circuit, from beginner-friendly panorama treks to technical peak climbs on Island Peak and Mera Peak, the region contains a trek for nearly every ambition and fitness level.

This guide provides everything you need to plan your Everest region adventure: 12 trek options with detailed comparisons, month-by-month weather analysis, complete permit requirements, realistic cost breakdowns across budget levels, altitude safety protocols, and guidance on choosing ethical, verified trekking operators.

Who this guide is for: First-time Nepal trekkers evaluating the Khumbu against other regions, experienced trekkers planning advanced routes like Three Passes or peak climbs, and anyone seeking practical decision-making information rather than generic travel inspiration.

1. Everest Base Camp Trek (Classic Route)

The Everest Base Camp trek remains Nepal's most famous trekking route and, for many, the defining Himalayan experience. The 130-kilometer round-trip journey from Lukla to Base Camp and back takes most trekkers 12–14 days and reaches a maximum altitude of 5,545 meters at Kala Patthar viewpoint.

What Makes This Trek Special

The EBC trek isn't just about reaching Base Camp—though standing where Everest expeditions launch is undeniably powerful. The route passes through the heart of Sherpa culture, with overnight stops in villages like Namche Bazaar (the region's trading hub), Tengboche (home to the Khumbu's most important monastery), and Dingboche (a high-altitude potato-farming village with spectacular Ama Dablam views).

Four of the world's fourteen 8,000-meter peaks are visible from this route: Everest (8,848m), Lhotse (8,516m), Makalu (8,485m), and Cho Oyu (8,188m). The Kala Patthar sunrise viewpoint offers arguably the best accessible view of Everest's summit pyramid.

Critical Acclimatization Points

Never skip the acclimatization days at Namche Bazaar (Day 3) and Dingboche (Day 6). These rest days follow the "climb high, sleep low" principle and dramatically reduce altitude sickness risk. Many trekkers who skip these days fail to reach Base Camp or require emergency evacuation.

Difficulty Assessment

The EBC trek is rated Moderate-Strenuous. The trekking itself isn't technically difficult—the trails are well-maintained and require no climbing skills. However, the altitude creates the challenge. You'll spend multiple days above 4,000m and sleep as high as 5,170m at Gorak Shep.

Physical requirements:

  • Ability to walk 5–7 hours daily on uneven terrain
  • Comfort ascending and descending 600–800 meters in a single day
  • Adequate cardiovascular fitness (preparation should include regular hiking and cardio training for 2–3 months before the trek)

What makes it manageable:

  • Teahouse accommodation means no heavy camping gear
  • Porters available to carry your main bag (duffel up to 10–15kg)
  • Well-established trail with no route-finding required
  • Emergency evacuation by helicopter available from multiple points

2. Three Passes Trek (Everest High Passes Circuit)

For trekkers seeking the Khumbu's most complete and challenging experience, the Three Passes Trek delivers. This 18–20 day circuit crosses three passes above 5,300 meters—Kongma La (5,535m), Cho La (5,420m), and Renjo La (5,360m)—and visits both Everest Base Camp and the Gokyo Lakes.

Why Choose Three Passes Over Classic EBC

The Three Passes Trek covers nearly everything the region offers in a single journey. You'll see Everest from multiple angles, visit both Kala Patthar and Gokyo Ri viewpoints, walk beside the Ngozumpa Glacier (Nepal's longest), and experience remote sections of the Khumbu that most trekkers never see.

The route also offers something the crowded EBC trail cannot: solitude. While the EBC route can feel like a highway during peak season, the pass-crossing sections see perhaps 10–20 trekkers per day rather than hundreds.

The Three Passes Explained

Kongma La (5,535m): The highest and most technical of the three passes, crossing from the Imja Valley to Lobuche. Requires scrambling over rocky terrain and possibly snow. Best crossed early morning when snow is firm.

Cho La (5,420m): The most frequently crossed pass, connecting Gokyo to Lobuche. Involves glacier travel on the eastern side. Microspikes or light crampons recommended. Can be dangerous in poor weather—groups sometimes wait 1–2 days for safe conditions.

Renjo La (5,360m): The most straightforward pass, connecting Gokyo to Thame and Namche. Still demanding at altitude but less technical than the others.

Direction of Travel

Most operators recommend the anti-clockwise direction (Lukla → Namche → Thame → Renjo La → Gokyo → Cho La → Lobuche → EBC → Kongma La → Chukhung → back to Namche).

Advantages of anti-clockwise:

  • Gradual altitude gain before first pass
  • Gokyo Lakes visited before the hardest section
  • Better acclimatization profile for Kongma La

Three Passes Is Not for Beginners

This trek requires prior high-altitude experience (minimum one trek above 4,500m), excellent fitness, and flexibility in your schedule. Pass conditions can force multi-day delays. Budget at least 2–3 extra days for weather contingencies.

Gear Requirements Beyond Standard EBC

  • Microspikes or light crampons: Essential for Cho La glacier crossing
  • Gaiters: Useful for snow on all three passes
  • Warmer sleeping bag: Rated to -20°C for high camps
  • Sunglasses with side shields: Intense high-altitude glare

3. Gokyo Lakes Trek

The Gokyo Lakes Trek offers the best alternative to the classic EBC route for trekkers who want fewer crowds, stunning scenery, and a slightly less demanding altitude profile.

The Gokyo Lakes System

Six glacial lakes (the "Gokyo Cho") sit at progressively higher altitudes above the village of Gokyo (4,790m). The turquoise lakes contrast dramatically with the gray moraine and white ice of the Ngozumpa Glacier—Nepal's longest glacier at 36 kilometers.

  • First Lake (Longponga): 4,690m
  • Second Lake (Taboche Tsho): 4,720m
  • Third Lake (Gokyo Cho/Dudh Pokhari): 4,750m—the largest, adjacent to Gokyo village
  • Fourth Lake (Thonak Cho): 4,870m
  • Fifth Lake (Ngozumpa Cho): 4,990m
  • Sixth Lake (Gyazumpa Cho): 5,010m—requires a separate day trip

Gokyo Ri vs. Kala Patthar

The 5,357m summit of Gokyo Ri offers what many consider superior views to Kala Patthar:

  • Panoramic range: Everest, Lhotse, Makalu, Cho Oyu, and Gyachung Kang (five 8,000m+ peaks) visible
  • Foreground interest: The lake system and glacier create a more compelling composition
  • Fewer crowds: Perhaps 30% of the trekkers compared to Kala Patthar

The trade-off: you don't reach Everest Base Camp itself.

Combining Gokyo with EBC via Cho La

The most popular extension connects Gokyo to the EBC trail via Cho La Pass (5,420m). This 16–18 day trek gives you both Gokyo Ri and Kala Patthar viewpoints, both the lake system and Base Camp.

Route: Lukla → Namche → Dole → Machhermo → Gokyo (acclimatize) → Cho La → Dzongla → Lobuche → Gorak Shep/EBC/Kala Patthar → descend via standard route

Cho La Crossing Conditions

Cho La Pass is only crossable in good weather. During the monsoon (June–August) and mid-winter (December–January), the pass may be snow-covered and dangerous. Even in peak season, groups occasionally wait 1–2 days for safe conditions. Build this flexibility into your itinerary.


4. Peak Climbing Options: Island Peak and Mera Peak

The Everest region offers Nepal's most accessible trekking peaks—mountains that require permits and basic mountaineering skills but don't demand expedition-level experience.

Island Peak (Imja Tse) — 6,189m

Island Peak sits in the Imja Valley near Chukhung, making it a natural extension of the EBC trek. Named by Eric Shipton because it resembles "an island in a sea of ice," the peak offers genuine mountaineering experience with manageable technical difficulty.

Technical requirements:

  • Comfort with fixed ropes and jumar (ascending device)
  • Crampon and ice axe competence on 45–50° slopes
  • Ladder crossing ability (similar to Everest's Khumbu Icefall)
  • Rope team travel on glacier

Typical itinerary: 16–18 days, combining EBC trek with 3–4 days for Island Peak attempt

Success rate: Approximately 60–70% in good conditions. Weather and snow conditions are the main limiting factors.

Cost: $2,500–$4,000 depending on group size and operator (includes climbing permit, equipment, and climbing guide)

Mera Peak — 6,476m

Mera Peak is Nepal's highest trekking peak and the most popular climbing peak in the country. Despite its height, it's considered less technical than Island Peak—the standard route involves no crevasse crossing or steep ice.

What makes Mera different:

  • Approach through remote Hinku Valley (no teahouses, camping required)
  • Higher altitude means more acclimatization time needed
  • Summit attempt is a long snow plod rather than technical climbing
  • Five 8,000m peaks visible from summit (Everest, Lhotse, Makalu, Kangchenjunga, Cho Oyu)

Physical requirements: Very high. The summit day is 8–10 hours of climbing at extreme altitude.

Typical itinerary: 18–22 days

Cost: $2,800–$4,500

Climbing Permits Required

Both Island Peak and Mera Peak require NMA (Nepal Mountaineering Association) climbing permits, which can only be obtained through registered trekking agencies. Solo permit applications are not accepted. Factor permit costs ($350 for Island Peak, $400 for Mera Peak in 2025) into your budget.

Permits and Fees: Complete 2025 Requirements

The Everest region permit system changed in 2022, simplifying requirements for most trekkers.

Required Permits

1. Sagarmatha National Park Entry Permit

  • Cost: NPR 3,000 (~$23 USD) for foreigners, NPR 1,500 for SAARC nationals
  • Where to obtain: Nepal Tourism Board office in Kathmandu OR Monjo checkpoint (on the trail)
  • Validity: Single entry, valid for the duration of your trek

2. Khumbu Pasang Lhamu Rural Municipality Entry Permit

  • Cost: NPR 2,000 (~$15 USD)
  • Where to obtain: Lukla (upon arrival) or Monjo checkpoint
  • Note: This replaced the previous TIMS card requirement for the Khumbu region

Total permit cost: Approximately $38–40 USD

TIMS Card No Longer Required

Since October 2018, the TIMS (Trekkers' Information Management System) card is NOT required for the Everest region. However, TIMS remains mandatory for Annapurna, Langtang, Manaslu, and other regions. Your agency may still register you in the TIMS system for safety tracking purposes.

Additional Permits for Specific Routes

Jiri/Phaplu approach (avoiding Lukla):

  • Gaurishankar Conservation Area Permit: NPR 3,000 if your route passes through this area

Peak climbing permits (Island Peak, Mera Peak):

  • NMA Climbing Permit: $350–$400 depending on peak
  • Must be obtained through a registered agency—no individual applications

Guide Requirements

Unlike Annapurna, Langtang, and Manaslu, the Everest region does not require mandatory guides or porters. The Khumbu Pasang Lhamu Rural Municipality opted out of Nepal's 2023 solo trekking ban.

However, hiring a guide is strongly recommended for:

  • First-time Nepal trekkers
  • Anyone attempting high passes (Three Passes, Cho La)
  • Peak climbing (required by permit conditions)
  • Trekkers without prior high-altitude experience

Cost Breakdown: What You'll Actually Spend

Understanding true trek costs prevents unpleasant surprises. Costs vary dramatically based on your style and choices.

Hidden Costs to Budget For

  1. Hot showers: NPR 300–500 ($2.50–4) per shower at higher elevations
  2. Charging electronics: NPR 300–500 per device per charge above Namche
  3. WiFi: NPR 300–500 per hour at higher elevations
  4. Bottled water: NPR 150–350 per liter (bring purification instead)
  5. Flight delays: Hotel and food costs if stranded in Lukla or Kathmandu
  6. Gear rental: $10–15/day for sleeping bag, down jacket if renting

Money on the Trail

ATMs exist only in Lukla and Namche Bazaar—and frequently run out of cash or malfunction. Bring sufficient Nepali rupees from Kathmandu for your entire trek. Budget NPR 3,000–5,000 per day ($25–40) for independent trekkers, less if your agency covers meals.


Getting There: Lukla Flights and Alternatives

The Lukla Flight Reality

Tenzing-Hillary Airport at Lukla (2,860m) is famously challenging—a 527-meter runway ending at a mountain wall. Weather conditions must be near-perfect for flights to operate.

What to expect:

  • Flight duration: 25–35 minutes from Kathmandu/Ramechhap
  • Aircraft: Twin Otter or similar small planes (15–20 passengers)
  • Peak season flights operate from Ramechhap (4–5 hour drive from Kathmandu) due to Kathmandu airport congestion
  • Off-season flights operate from Kathmandu's Tribhuvan Airport

Delay statistics:

  • October–November: Approximately 40–50% of flights experience some delay
  • Morning flights most reliable; afternoon flights frequently cancelled
  • Multi-day groundings occur several times per season

Essential Flight Strategies

  1. Book the earliest flight available: 6:00–6:30 AM departures have highest success rates
  2. Build 2–3 buffer days into your itinerary: Never book international flights for the day after your scheduled return flight
  3. Have helicopter backup in mind: Helicopter flights ($500–700 one-way) operate in marginal conditions when planes can't
  4. Consider Ramechhap logistics: Peak season flights require 4:00 AM departures from Kathmandu

Alternatives to Flying

Helicopter to Lukla:

  • More weather-tolerant than fixed-wing
  • Cost: $500–700 per person (shared) or $3,000–4,000 (private charter)
  • Flight time: 45 minutes from Kathmandu

Trek from Jiri (19–22 days total):

  • The original Hillary approach before Lukla airport existed
  • Natural acclimatization—virtually eliminates altitude sickness risk
  • Lower costs (no flights), fewer crowds, cultural immersion
  • Adds 7–8 trekking days each way

Trek from Phaplu (adds 3–4 days):

  • Compromise between Lukla and Jiri
  • Small airstrip with daily flights (more reliable than Lukla)
  • Adds 3–4 trekking days to reach Lukla trail junction

Jeep to Salleri/Phaplu:

  • 10–12 hour drive from Kathmandu
  • Budget option, no flight dependency
  • Rough roads, not for those prone to motion sickness

Altitude Sickness: Prevention, Recognition, and Response

Altitude sickness (Acute Mountain Sickness/AMS) is the primary health risk on Everest region treks. Understanding it thoroughly can save your life.

How AMS Develops

Above 2,500m, the reduced air pressure means less oxygen per breath. Your body compensates by breathing faster, producing more red blood cells, and increasing blood flow—but these adaptations take days to weeks. AMS occurs when you ascend faster than your body can adapt.

Key statistics:

  • 25–30% of trekkers experience some AMS symptoms at Namche Bazaar (3,440m)
  • Symptoms typically appear 6–24 hours after reaching a new altitude
  • Fitness level does NOT predict AMS susceptibility—young, fit trekkers are equally vulnerable

Recognizing Symptoms

Mild AMS (common, manageable):

  • Headache (the hallmark symptom)
  • Fatigue beyond normal tiredness
  • Loss of appetite
  • Nausea
  • Difficulty sleeping

Moderate AMS (requires action):

  • Severe headache unrelieved by ibuprofen/paracetamol
  • Vomiting
  • Decreased coordination
  • Shortness of breath at rest

Severe AMS / HACE / HAPE (medical emergency):

  • Confusion, disorientation
  • Inability to walk straight
  • Persistent cough, possibly with pink frothy sputum (HAPE)
  • Extreme fatigue
  • Blue lips or fingernails

The Golden Rule of Altitude

Never ascend to sleep at a higher altitude if you have ANY symptoms of AMS. Either rest at current altitude until symptoms resolve, or descend. Ignoring symptoms and continuing upward can be fatal.

Prevention Strategies

  1. Follow proper acclimatization schedule: Never skip rest days at Namche and Dingboche
  2. Climb high, sleep low: Day hikes to higher elevations aid acclimatization
  3. Limit altitude gain: Maximum 300–500m of sleeping altitude gain per day above 3,000m
  4. Hydrate aggressively: 3–4 liters per day
  5. Avoid alcohol: Especially in first days at altitude
  6. Consider Diamox (Acetazolamide): Consult a doctor before your trip

Diamox notes:

  • Typical preventive dose: 125mg twice daily, starting 24 hours before ascent
  • Helps speed acclimatization, doesn't mask symptoms
  • Common side effects: tingling in fingers/toes, increased urination, altered taste of carbonated drinks
  • Not suitable for those with sulfa allergies

Emergency Response

If someone develops moderate-to-severe symptoms:

  1. Stop ascending immediately
  2. Descend if possible—even 300–500m can bring relief
  3. Administer supplemental oxygen if available
  4. Arrange evacuation if symptoms don't improve with descent

Helicopter evacuation is available from most points on the trail. Your travel insurance must specifically cover high-altitude evacuation above 5,000m and helicopter rescue. Evacuation costs $3,000–$5,000 without insurance.


Teahouse Accommodation: What to Expect

The Everest region's teahouse network makes trekking accessible—you don't need tents or cooking gear. But expectations should be calibrated to altitude.

Lower Elevations (Lukla to Namche, 2,800–3,500m)

Modern lodges with:

  • Private rooms (twin beds with thin walls)
  • Attached or nearby Western toilets
  • Hot showers (often solar-heated)
  • Charging stations (often free or low cost)
  • WiFi (NPR 200–300/hour)
  • Diverse menus including Western options
  • Common rooms with heating stoves

Cost: $5–15 per room per night

Mid-Elevations (Namche to Dingboche, 3,500–4,400m)

Good but simpler lodges with:

  • Private rooms (no heating in rooms)
  • Shared squat toilets (some Western)
  • Hot showers (gas or solar, NPR 300–400)
  • Charging available (NPR 300–500)
  • Slower WiFi (NPR 300–500/hour)
  • Heated common dining room (often the only warm space)

Cost: $8–20 per room per night

High Elevations (Lobuche to Gorak Shep, 4,900–5,170m)

Basic but functional lodges with:

  • Simple rooms, walls that don't reach ceiling
  • Squat toilets (may freeze overnight)
  • Unreliable or no hot showers
  • Expensive charging (NPR 500–700)
  • Limited menu (altitude affects cooking and appetite)
  • Single heated common room
  • Expect temperatures at or below freezing in rooms overnight

Cost: $10–25 per room per night

Teahouse Etiquette

  • Eat where you sleep: Teahouses offer low room rates expecting you'll buy meals there. Eating elsewhere is considered poor form.
  • Order in advance: Kitchens work slowly at altitude. Place dinner orders upon arrival.
  • Bring a sleeping bag: Even with blankets provided, you'll need your own warm sleep system.
  • Carry earplugs: Thin walls mean you'll hear everything.

Luxury Lodge Options

Premium lodges exist at strategic points:

Yeti Mountain Home (Lukla, Namche, Kongde, Thame): $150–300/night, private bathrooms, heating, Western amenities

Everest Summit Lodges (Tashinga, Mende, Pangboche): $200–400/night, similar premium standard

These book out months in advance during peak season. They're excellent for those wanting comfort but still the trekking experience.


Packing Essentials: Gear Checklist by Category

Clothing (Layering System)

Base Layers (2–3 sets):

  • Merino wool or synthetic long-sleeve tops
  • Merino wool or synthetic leggings
  • Avoid cotton—it retains moisture and loses insulation when wet

Mid Layers:

  • Fleece jacket or vest (100–200 weight)
  • Down or synthetic puffy jacket (for higher elevations and evenings)
  • Softshell jacket for active hiking

Outer Layers:

  • Waterproof/breathable shell jacket (Gore-Tex or equivalent)
  • Waterproof pants (even in dry season, useful for wind protection)

Lower Body:

  • Trekking pants (2 pairs, zip-off style useful)

Accessories:

  • Warm hat (beanie)
  • Sun hat with brim
  • Buff/neck gaiter
  • Liner gloves + insulated gloves or mittens
  • Warm socks (3–4 pairs merino wool)

Footwear

  • Trekking boots: Broken-in, ankle-supporting, waterproof. Do NOT buy new boots in Kathmandu—quality is questionable and break-in time insufficient.
  • Camp shoes: Lightweight sandals or down booties for teahouses
  • Gaiters: Optional for main EBC, recommended for passes

Equipment

  • Daypack: 25–35L, comfortable with hip belt
  • Duffel bag: 50–70L for porter to carry (max 15kg total)
  • Sleeping bag: Rated to -15°C minimum, -20°C for Three Passes/winter
  • Trekking poles: Highly recommended—protect knees on descents
  • Headlamp: Plus spare batteries
  • Water bottles/bladder: 2–3L capacity total
  • Water purification: Tablets, SteriPen, or filter

Electronics

  • Phone/camera
  • Power bank: 20,000mAh+ recommended
  • Charging cables
  • Universal adapter: Nepal uses types C, D, and M sockets

Personal Items

  • Sunscreen: SPF 50+, high altitude = intense UV
  • Lip balm with SPF
  • Sunglasses: Category 3–4, wraparound or side shields
  • First aid kit: Including Diamox, pain relievers, blister treatment, anti-diarrheal
  • Toiletries: Minimal—biodegradable soap, hand sanitizer, wet wipes
  • Toilet paper: Not always available at teahouses

Rent vs. Buy

Down jackets and sleeping bags can be rented in Kathmandu for $1–2/day each. Quality varies—inspect carefully. For multi-week treks, buying may be more economical. Thamel shops sell gear ranging from counterfeit (avoid) to genuine brand overstock (good value).


Hiring Guides and Porters

Do You Need a Guide?

Unlike other Nepal trekking regions, the Khumbu does not legally require guides. The trail is well-marked, teahouses are frequent, and many trekkers complete EBC independently.

When to hire a guide:

  • First-time Nepal/high-altitude trekkers
  • Three Passes or other technical routes
  • Peak climbing (required by permit)
  • Anyone wanting cultural interpretation and local knowledge
  • Solo trekkers (for safety backup)

When you might skip a guide:

  • Experienced Himalayan trekkers
  • Groups of 3+ with prior high-altitude experience
  • Budget-focused trekkers comfortable with self-navigation

Guide Types and Costs

Licensed Trekking Guide:

  • Training: Government-certified, first aid trained
  • Cost: $25–50/day plus food, accommodation, and insurance
  • Services: Navigation, cultural interpretation, safety decisions, emergency coordination

Porter-Guide:

  • Training: Variable—often experienced but not formally certified
  • Cost: $20–30/day
  • Services: Carries your bag AND provides basic guiding
  • Best for: Budget trekkers wanting carrying help with some guidance

Porter Only:

  • Cost: $20–25/day
  • Services: Carries your duffel (max 20–25kg—ethical limit)
  • You handle navigation independently

Ethical Hiring Practices

The trekking industry has well-documented issues with porter exploitation. Ethical trekking means:

  1. Reasonable loads: Maximum 20–25kg per porter. Never allow overloading.
  2. Proper equipment: Porters should have adequate footwear, warm clothing, and rain gear. Some agencies provide gear; verify this.
  3. Fair wages: Ensure your agency pays porters directly—minimum $20/day plus meals and accommodation.
  4. Insurance: Porters should have accident insurance covering medical evacuation.
  5. Shared lodging: Porters should sleep in proper shelter, not storage rooms.

Ask your agency directly: "What is your porter welfare policy?" Agencies certified by organizations like Travelife or participating in the Porters' Progress initiative maintain higher standards.

Tipping Guidelines

Tipping is customary and important—these wages are still modest for demanding work:

  • Guide: $5–10/day → $60–140 for 12-day trek
  • Porter: $3–5/day → $35–60 for 12-day trek
  • Porter-Guide: $5–8/day → $60–95 for 12-day trek

Tip in Nepali rupees at the end of the trek. Express appreciation directly and personally.


Food and Hydration

What to Expect at Teahouses

Menus are surprisingly extensive, but certain items become unavailable or expensive at altitude.

Widely available:

  • Dal bhat (rice, lentil soup, vegetables, pickles)—often unlimited refills
  • Momos (Nepali dumplings)
  • Fried rice/noodles
  • Pasta dishes
  • Soups (garlic soup is a local altitude remedy)
  • Pancakes, porridge, eggs (breakfast)
  • Basic bread and chapati

Available but expensive at altitude:

  • Pizza, burgers
  • Steaks (often yak or buff)
  • Desserts

Pricing:

  • Dal bhat: $5–10 depending on altitude
  • Pasta/rice dishes: $6–12
  • Tea/coffee: $2–4
  • Bottled water (1L): $2–4

Hydration Strategy

At altitude, you need 3–4 liters of fluid daily. Buying bottled water is expensive ($3–4/liter at high camps) and creates plastic waste.

Better options:

  • Water purification tablets: Inexpensive, lightweight (Aquatabs, Micropur)
  • SteriPen UV purifier: Fast, effective for clear water
  • Sawyer filter: Reliable backup

Most teahouses sell boiled water for NPR 150–300/liter—more economical and environmentally friendly than bottles.

Hydration tips:

  • Start each day with a full liter before trekking
  • Don't wait until thirsty—sip continuously
  • Monitor urine color (pale yellow = well hydrated)
  • Hot drinks (tea, soup) count toward intake and help warming

Common Mistakes and How to Avoid Them

Mistake 1: Insufficient Buffer Days

The problem: Booking international flights the day after scheduled return from Lukla. Flights cancel frequently; multi-day delays happen several times per month.

The solution: Build 2–3 extra days into your schedule. If flights run smoothly, enjoy extra Kathmandu time.

Mistake 2: Skipping Acclimatization Days

The problem: Feeling good at Namche and pushing on without the rest day. AMS symptoms often appear 12–24 hours after ascent.

The solution: Take rest days as scheduled, regardless of how you feel. Use them for acclimatization hikes (climb high, sleep low).

Mistake 3: Over-Packing

The problem: Bringing 20kg of gear when 10kg suffices. Heavy packs cause fatigue and injury.

The solution: If a porter carries your duffel, your daypack should be 5–7kg maximum. If self-carrying, aim for 10kg total including water and layers.

Mistake 4: Inadequate Travel Insurance

The problem: Standard travel insurance often excludes altitudes above 3,000–4,000m. Helicopter evacuation costs $3,000–5,000 out of pocket.

The solution: Purchase trekking-specific insurance covering minimum 6,000m altitude (for EBC) and helicopter evacuation. World Nomads, Global Rescue, and Battleface offer suitable policies.

Mistake 5: Ignoring Early Symptoms

The problem: Pushing through headaches and nausea hoping they'll resolve.

The solution: Treat any symptoms seriously. Rest an extra day. Descend if symptoms persist. Your trekking goals are not worth your life.

Mistake 6: Cash Shortages

The problem: Assuming ATMs will work in Namche. They frequently malfunction or run out of cash.

The solution: Bring all needed cash from Kathmandu. Budget NPR 3,000–5,000/day ($25–40) for independent trekking; less with an all-inclusive package.

Mistake 7: New Boots

The problem: Buying trekking boots in Kathmandu and starting immediately.

The solution: Break in boots for minimum 2–3 weeks before your trek. Quality in Kathmandu shops is inconsistent—bring trusted footwear from home.

Mistake 8: Underestimating the Cold

The problem: Assuming teahouses will be warm enough without proper gear.

The solution: Rooms at high elevation have no heating and drop to freezing overnight. A quality sleeping bag (-15°C or colder rating) and warm layers are essential, not optional.


Choosing a Trekking Agency

Why Use an Agency?

Even if guides aren't required, agencies provide:

  • Permit processing
  • Lukla flight booking (they get allocation priority)
  • Trained, insured guides and porters
  • Emergency response coordination
  • Accommodation reservations (critical in peak season)
  • Logistical problem-solving

What to Look For

Essential criteria:

  • Registered with Nepal Tourism Board and TAAN (Trekking Agencies' Association of Nepal)
  • Clear permit and fee breakdown
  • Written porter welfare policy
  • Guide first-aid certification
  • Evacuation and emergency protocols
  • Verified insurance for staff

Quality indicators:

  • Route-specific experience (especially for Three Passes, peak climbs)
  • Small group sizes (8 or fewer)
  • Pre-departure communication and briefing
  • Transparent pricing (no hidden costs)
  • Responsive to questions before booking

Red flags:

  • Prices dramatically below market ($700 for all-inclusive EBC when average is $1,200+)
  • Vague answers about guide qualifications
  • No clear porter weight/welfare policy
  • Pressure to book immediately
  • No physical office in Kathmandu

Questions to Ask Before Booking

  1. "What is included and excluded? Can I see a detailed breakdown?"
  2. "What are your acclimatization policies?"
  3. "What happens if I need to evacuate?"
  4. "What is your porter welfare policy—weight limits, gear, accommodation?"
  5. "Can I speak with a previous client?"
  6. "What are your guide-to-trekker ratios?"
  7. "What's your contingency for Lukla flight cancellations?"
