Renjo La Pass Guide: The Scenic Route to Gokyo Lakes (5,360m)

Renjo La Pass (5,360m/17,585ft) stands as the western gateway to Gokyo Valley, offering what many experienced trekkers consider the finest panoramic view in the Everest region. While Cho La and Kongma La receive more attention in Three Passes Trek discussions, Renjo La delivers an extraordinary visual reward that rivals anything the Himalaya can offer: a sweeping vista that encompasses Everest, Lhotse, Makalu, Cho Oyu, and the entire turquoise chain of Gokyo Lakes spread below.

This comprehensive guide covers everything you need to successfully cross Renjo La Pass, whether you're approaching it as part of the complete Three Passes Trek or using it as an alternative route to reach Gokyo Valley from Namche Bazaar. You'll learn the optimal routes, timing considerations, weather windows, difficulty factors, and practical logistics that separate a successful crossing from a challenging ordeal.

Why Choose Renjo La Pass?

Among the three high passes of the Everest region, Renjo La offers distinct advantages that make it the preferred choice for many experienced trekkers:

The View Factor

The summit of Renjo La delivers what many consider the single best viewpoint in the entire Everest region. Unlike Kala Patthar or Gokyo Ri, which require additional side trips, Renjo La's summit is part of your trekking route—the spectacular panorama comes included in the crossing.

From the pass, you'll witness:

To the East:

• Mount Everest (8,849m) rising prominently above the Ngozumpa Glacier
• Lhotse (8,516m) appearing as Everest's dramatic south face neighbor
• Nuptse's imposing rock walls
• The complete Gokyo Lakes chain stretching below
• Ngozumpa Glacier—the longest glacier in Nepal

To the South:

• Thamserku (6,623m) dominating the middle distance
• Kangtega (6,782m) showing its distinctive profile
• Ama Dablam (6,812m) appearing on clear days

To the West and North:

• Cho Oyu (8,188m), the world's sixth-highest peak, appearing remarkably close
• Gyachung Kang (7,952m)
• The Tibetan Plateau stretching beyond the border

Fewer Crowds

Renjo La sees significantly less traffic than the main Everest Base Camp trail or even Cho La Pass. While October mornings at Cho La can feel congested with trekking groups, Renjo La often offers solitude. You might share the pass with only a handful of other trekkers, creating a more intimate mountain experience.

Western Approach Benefits

Coming from Thame and Lungden provides cultural immersion often missed on the standard EBC route. Thame village remains authentically Sherpa, less affected by tourism than Namche. The monastery at Thame hosts important religious ceremonies and offers genuine insight into Buddhist mountain culture.

Acclimatization Advantages

For Three Passes trekkers starting from Namche and heading west first, Renjo La serves as an excellent first high pass. After acclimatizing in Namche (3,440m) and spending time at Thame (3,820m), the gradual approach to Lungden (4,380m) prepares your body well before attempting 5,360m.

Understanding the Routes to Renjo La

Route 1: Namche to Thame to Lungden (Recommended)

This is the standard and most popular approach, offering the best acclimatization profile and teahouse accommodation throughout.

Day-by-Day Breakdown:

Namche Bazaar (3,440m) to Thame (3,820m)

• Distance: 10km
• Time: 4-5 hours
• Elevation gain: 380m
• Trail character: Gentle gradient following the Bhote Koshi river valley

The trail from Namche initially descends before contouring along the hillside above the river. You'll pass through Thamo Og, a small settlement with basic teahouses, before continuing through rhododendron and juniper forests. The path remains well-defined and relatively easy—an excellent acclimatization day.

Thame village sits in a wide valley surrounded by 6,000m peaks. The famous Thame Monastery, perched on a ridge above the village, is worth the 30-minute climb for sunset views and spiritual atmosphere. Tenzing Norgay, the first person to summit Everest with Edmund Hillary, was born in a village near Thame.

Thame (3,820m) to Lungden (4,380m)

• Distance: 8km
• Time: 4-5 hours
• Elevation gain: 560m
• Trail character: Valley floor walking, gradual ascent

From Thame, the trail continues up the Bhote Koshi valley toward the Tibetan border. The landscape becomes increasingly stark and beautiful—fewer trees, more moraines, bigger views. You'll pass Marulung, a seasonal yak herding settlement, before reaching Lungden (also spelled Lundin or Lumding).

Lungden offers basic but adequate teahouse accommodation. Expect:

• Simple twin rooms
• Common dining area with heating stove
• Basic dal bhat and noodle dishes
• Limited electricity (solar)
• No hot showers
• Pit toilets

Lungden (4,380m) to Gokyo (4,790m) via Renjo La (5,360m)

• Distance: 10km
• Time: 7-9 hours
• Elevation gain to pass: 980m
• Elevation loss to Gokyo: 570m
• Trail character: Steep rocky climb, technical descent

This is the big day. Most trekkers depart Lungden at 4:00-5:00 AM to cross the pass during optimal morning conditions. The trail climbs steeply through moraines and boulder fields before reaching the prayer flag-adorned summit. The descent to Gokyo follows a similarly steep path down to the fourth Gokyo Lake, then along the lakeshore to Gokyo village.

Route 2: Direct from Thame (Longer Day)

Some very fit, well-acclimatized trekkers skip Lungden and cross directly from Thame in a single long day.

Thame to Gokyo via Renjo La

• Distance: 18km
• Time: 10-12 hours
• Elevation gain to pass: 1,540m
• Net elevation gain: 970m

This route requires:

• Excellent fitness
• Previous high-altitude experience
• Perfect weather conditions
• Early departure (2:00-3:00 AM)
• Strong acclimatization (at least 4-5 nights above 3,500m)

Route 3: Gokyo to Lungden/Thame (Reverse Crossing)

Some Three Passes trekkers cross Renjo La east to west, approaching from Gokyo after climbing Gokyo Ri and exploring the valley.

Gokyo to Lungden via Renjo La

• Distance: 10km
• Time: 8-10 hours
• Elevation gain to pass: 570m
• Elevation loss to Lungden: 980m

The reverse direction presents different challenges:

• Less steep initial ascent but longer climb
• More technically challenging descent (loose rock, steeper sections)
• Afternoon light not optimal for Everest views
• Arrives at smaller village with basic accommodation

Advantages of reverse crossing:

• Already well-acclimatized from Gokyo Ri climb
• Can combine with Gokyo exploration before crossing
• Less crowded timing (most trekkers go west to east)

The Crossing Day: What to Expect

Pre-Dawn Departure

Plan to leave Lungden between 4:00-5:00 AM. Early departure ensures:

• Crossing before afternoon clouds roll in
• Frozen moraine surfaces (easier walking than softened afternoon snow)
• Maximum daylight buffer for unexpected delays
• Best photography light at the summit

Prepare the night before:

• Pack your daypack completely
• Lay out all clothing layers
• Fill water bottles (they may freeze overnight)
• Charge headlamp and bring spare batteries
• Set multiple alarms
• Eat a substantial dinner

Section 1: Lungden to Moraine (1-2 hours)

The initial trail from Lungden follows the valley floor before beginning its ascent. Walking in darkness with headlamps, you'll navigate a relatively clear path through sparse vegetation and rocky terrain. This section allows your body to warm up before the steep climbing begins.

As dawn breaks, you'll reach the base of the main moraine. Pause here to:

• Switch off headlamps
• Remove a layer (you'll be warming up)
• Drink water before the hard climbing
• Take photos of the emerging peaks

Section 2: Moraine Ascent (2-3 hours)

This is the most physically demanding section. The trail climbs steeply through loose rock, boulder fields, and occasional snow patches. There is no defined path in many areas—follow cairns (stone markers) and your guide's lead.

Physical challenges:

• Altitude making each step harder
• Loose footing requiring careful placement
• Steep grade demanding sustained effort
• Cold temperatures until sun hits the slope

Navigation notes:

• Cairns mark the general route but can be obscured by snow
• Multiple paths exist through the boulder field—all lead to the pass
• False summits will test your patience
• The actual pass is marked by prayer flags visible from distance

Section 3: Final Approach and Summit (30-60 minutes)

The final approach to Renjo La's summit crosses occasional snow fields depending on season. In October-November, expect patchy snow. In spring (March-May), more snow may be present but usually not requiring crampons.

At the Summit (5,360m):

Expect to spend 15-30 minutes at the pass:

• Prayer flags flutter in persistent wind
• Small cairn marks the highest point
• Panoramic view in all directions (weather permitting)
• Cold temperatures require down jacket even in sunshine
• Photograph opportunity of a lifetime

The view from Renjo La is extraordinary. On clear mornings, you'll see:

• Everest, Lhotse, and Makalu appearing as a mountain trinity to the east
• The Ngozumpa Glacier sprawling below, Nepal's longest ice river
• All six Gokyo Lakes visible as turquoise jewels
• Cho Oyu dominating the northern skyline
• Distant Tibetan peaks beyond the border

Section 4: Descent to Gokyo (3-4 hours)

The descent to Gokyo is steeper and more technical than the ascent. Trekking poles are essential for stability on the loose rock and occasional ice.

Descent stages:

Upper descent (1-1.5 hours): Very steep, loose rock, careful foot placement required. This section demands full concentration—more injuries occur on descent than ascent.

Fourth Lake approach (1-1.5 hours): The gradient eases as you approach the fourth Gokyo Lake (Thonak Tsho). The turquoise water provides excellent photo opportunities with Everest reflected in calm morning conditions.

Lake path to Gokyo (1 hour): A pleasant walk along the lake shores to Gokyo village. You'll pass the third lake (Dudh Pokhari) before reaching your destination.

Arrival in Gokyo: Most trekkers arrive between 1:00-3:00 PM, allowing time to:

• Secure accommodation
• Eat a substantial meal
• Rest before potential Gokyo Ri climb the following day
• Celebrate a successful crossing

When to Cross Renjo La: Timing and Weather

Best Months

October-November (Autumn):

• Clearest skies and best visibility
• Stable weather patterns
• Cold but manageable temperatures
• Trail generally snow-free
• Highest number of trekkers (though still fewer than main EBC trail)

March-May (Spring):

• Good visibility, especially March-early April
• Warmer temperatures during crossing
• More snow on the pass (may need caution)
• Rhododendron blooms in lower elevations
• Slightly fewer trekkers than autumn

Shoulder Season Considerations

Early September:

• Monsoon ending, weather improving
• Some rain possible
• Fewer trekkers
• Lodges in Lungden may just be opening

December:

• Cold but often clear
• Less snow than you'd expect
• Very few trekkers
• Some lodges may close

January-February:

• Very cold, especially at night (-20°C to -30°C at Lungden)
• Generally clear days
• Minimal trekker presence
• Some lodges closed—confirm availability

Daily Weather Patterns

Regardless of season, Himalayan weather follows predictable daily patterns:

5:00-9:00 AM: Generally clearest conditions, ideal for summit photography and safe crossing

9:00 AM-12:00 PM: Clouds begin forming in valleys, rising up slopes

12:00-3:00 PM: Clouds often obscure views, precipitation possible

3:00-6:00 PM: Clouds typically clear somewhat before sunset

Planning implication: Always aim to cross the pass before noon. Early departure is not optional—it's essential for safety and views.

Difficulty Assessment: Is Renjo La Hard?

Physical Demands

Renjo La is classified as "strenuous" or "challenging" among the three Everest region passes. Here's how it compares:

Renjo La (5,360m):

• Longest sustained climb of the three passes
• More gradual approach than Cho La
• Less technical than Kongma La
• Longer total crossing time
• Well-defined (if rough) trail throughout

Cho La (5,420m):

• Higher altitude
• Shorter but steeper approach
• More technical (glacier crossing, potential ice)
• May require crampons in some conditions

Kongma La (5,535m):

• Highest of the three
• Most technical approach and descent
• Less frequently crossed
• Most demanding overall

Fitness Requirements

To successfully cross Renjo La, you should be able to:

• Trek 8-10 hours in a single day
• Climb 1,000m of elevation gain at altitude
• Navigate loose rocky terrain for several hours
• Function effectively at 5,000m+ altitude
• Carry a 5-8kg daypack throughout

Recommended preparation:

• Regular cardio exercise (running, cycling, swimming) for 2-3 months before trek
• Hiking with elevation gain, preferably at altitude if accessible
• Core and leg strength training
• Prior trekking experience, ideally above 4,000m

Technical Requirements

Renjo La is non-technical in mountaineering terms—no ropes, ice axes, or specialized climbing skills required. However, you'll need:

• Confidence on steep, loose terrain
• Comfort with exposure (some sections have steep drop-offs)
• Ability to follow cairns in poor visibility
• Basic navigation awareness

Gear requirements:

• Sturdy trekking boots (ankle support essential)
• Trekking poles (highly recommended)
• Warm layers (temperatures at pass can be -10°C to -20°C even in October)
• Headlamp for pre-dawn departure
• Sunglasses and sunscreen (snow reflection intense)
• Gaiters helpful for occasional snow sections

Altitude Considerations

At 5,360m, Renjo La puts you firmly in the high-altitude zone where Acute Mountain Sickness (AMS) is a real risk.

Before attempting Renjo La, ensure you have:

• Spent at least 3-4 nights acclimatizing above 3,500m
• No current symptoms of AMS (headache, nausea, dizziness)
• Properly hydrated (3-4 liters daily in preceding days)
• Slept well at altitude (fatigue increases AMS risk)

Recommended acclimatization schedule:

1. Kathmandu (1,400m) - 1-2 nights
2. Namche Bazaar (3,440m) - 2 nights (with acclimatization day)
3. Thame (3,820m) - 1-2 nights
4. Lungden (4,380m) - 1 night
5. Cross to Gokyo (4,790m)

This schedule provides 5-7 days of altitude exposure before attempting the pass—generally adequate for most trekkers.

Camping Options

While most trekkers use teahouse accommodation at Lungden, camping is an option for those who prefer or require it.

Why Camp?

• Teahouses full (possible in peak October)
• Teahouses closed (off-season)
• Preference for camping experience
• Flexibility in timing
• Part of organized camping trek

Camping Logistics

Camping on the Renjo La route requires:

Equipment (arranged through trekking agency):

• 4-season tent rated for high altitude
• Sleeping bag (-20°C rating minimum)
• Sleeping pad with high R-value
• Cooking equipment and fuel
• Food supplies

Common camping spots:

Lungden area (4,380m): Flat areas near the teahouses, water available from stream

Renjo La approach (4,800-5,000m): Emergency bivouac only—exposed and cold, no water sources

Above fourth Gokyo Lake (4,700m): Alternative to crowded Gokyo village, spectacular setting

Camping Considerations

Alternative Routes and Options

Alternative 1: Gokyo via Machhermo (Skip Renjo La)

If weather prevents Renjo La crossing or you prefer a less challenging route, you can reach Gokyo via the standard trail from Namche:

Namche → Dole → Machhermo → Gokyo

This route:

• Avoids high pass entirely
• Takes 3 days from Namche
• Follows well-established teahouse trail
• Less scenic but more reliable
• Good fallback option if weather deteriorates

Alternative 2: Combine with Cho La

Many Three Passes trekkers combine Renjo La with Cho La Pass for a complete Gokyo-Everest circuit:

Common itinerary:

1. Namche to Thame
2. Thame to Lungden
3. Lungden to Gokyo (via Renjo La)
4. Gokyo acclimatization (climb Gokyo Ri)
5. Gokyo to Thagnak
6. Thagnak to Dzongla (via Cho La)
7. Continue to EBC

This combination provides two high passes with excellent views and a comprehensive Everest region experience.

Alternative 3: Return Same Way

If conditions prevent onward travel from Renjo La summit (weather deteriorating, injury, altitude sickness), you can always return to Lungden. This is a legitimate decision, not a failure. The mountains will still be there for another attempt.

Practical Logistics

Permits Required

Sagarmatha National Park Entry Permit: $30 USD, obtained in Kathmandu (Nepal Tourism Board office) or at Monjo checkpoint

TIMS Card (Trekkers' Information Management System): Free when arranged through registered trekking agency

Khumbu Pasang Lhamu Rural Municipality Fee: $20 USD, payable at Lukla or Monjo

Guide Requirements

As of 2024, Nepal requires foreign trekkers to hire a licensed guide or porter for treks in national parks, including the entire Everest region. Solo trekking is no longer permitted.

For Renjo La specifically, a guide is especially valuable for:

• Navigation in poor visibility
• Weather assessment and safety decisions
• Emergency response if altitude sickness occurs
• Local knowledge of trail conditions

Accommodation Booking

Thame: Multiple teahouses, booking usually not necessary except peak October

Lungden: Only 2-3 basic lodges. In peak season, your guide should call ahead to confirm availability. Off-season, lodges may be closed.

Gokyo: Numerous teahouses of varying quality. Peak season may require early arrival to secure rooms.

Cost Considerations

Budget for the Renjo La section of your trek:

| Item | Cost (USD) | |------|------------| | Thame teahouse | $5-8/night | | Lungden teahouse | $10-15/night | | Meals in Thame | $15-20/day | | Meals in Lungden | $20-25/day | | Guide daily rate | $25-35/day | | Porter (optional) | $20-25/day |

Total Namche-Gokyo via Renjo La (3 days): $150-250 USD depending on choices

Emergency Information

Nearest medical facilities:

• Kunde Hospital (near Namche): Basic medical care, altitude expertise
• Kathmandu: Full medical facilities (helicopter evacuation required)

Helicopter evacuation cost: $5,000-8,000 USD from Gokyo/Renjo La area

Insurance requirement: Ensure your travel insurance covers trekking to 6,000m and helicopter evacuation. Verify altitude coverage before departing home country.

Frequently Asked Questions

Is Renjo La harder than Cho La?

Renjo La is generally considered slightly easier than Cho La. While both reach similar altitudes (5,360m vs 5,420m), Cho La involves a glacier crossing that can be technical when icy, and its steep descent requires more care. Renjo La has a longer, more gradual approach and descent on rocky terrain throughout—challenging but less technical.

Can I cross Renjo La without a guide?

Legally, no. Nepal requires foreign trekkers to have a licensed guide or porter for treks in national parks as of 2024. Practically, attempting Renjo La without a guide is inadvisable due to navigation challenges in poor visibility and the remote location if problems arise.

What if weather prevents crossing?

Wait in Lungden for improvement (if lodges open) or return to Thame. Your guide will make weather assessments each morning. If multiple bad weather days occur, consider the alternative route to Gokyo via Machhermo. Flexibility in scheduling is essential for high pass trekking.

How cold is it at Renjo La summit?

Expect temperatures between -5°C to -15°C at the pass in October-November, potentially colder in winter months. Wind chill can make it feel significantly colder. Dress in layers with a down jacket accessible for the summit stop.

Is there phone signal on Renjo La?

Generally no. Phone signal is unreliable above Thame and non-existent at the pass. Inform family of crossing day timing before departing areas with connectivity. Your guide should carry emergency communication equipment.

Can I cross Renjo La in monsoon (June-August)?

Not recommended. Monsoon brings cloud, rain, snow at altitude, and significantly increased risk. Visibility is typically poor, trails can be dangerous, and the experience is compromised. Wait for post-monsoon (late September onward) for safe crossing.

Should I climb Gokyo Ri after crossing Renjo La?

Take a rest day in Gokyo before attempting Gokyo Ri. Crossing Renjo La and climbing Gokyo Ri on consecutive days is exhausting and increases altitude sickness risk. Most itineraries include a full acclimatization day in Gokyo specifically for the Gokyo Ri climb.
