The Cho La Pass trek combining Gokyo Lakes with EBC is the finest single trek available in the Everest region, and most experienced Himalayan trekkers agree on this without much debate. It combines everything the Everest region offers — five Gokyo Lakes, Gokyo Ri’s panorama, the Cho La Pass at 5,420m, Everest Base Camp, and Kala Patthar at 5,545m. The circuit is genuinely circular, with no retracing between the two valleys, so every day delivers new terrain and a new angle on the Khumbu.

Gokyo Lakes EBC Cho La Pass — Route Overview
The Cho La Pass trek circuit begins and ends at Lukla. The route follows the standard trail to Namche before branching into the Gokyo Valley — visiting the lakes, summiting Gokyo Ri, and crossing the Cho La east into the Khumbu. From there it continues to EBC and Kala Patthar before descending to Lukla.
Complete route — village by village
Lukla → Phakding → Namche Bazaar → Dole → Machhermo → Gokyo → Gokyo Ri (5,357m) → Cho La Pass (5,420m) → Dzongla → Lobuche → Gorakshep → Everest Base Camp (5,364m) → Kala Patthar (5,545m) → Pheriche → Namche Bazaar → Phakding → Lukla
What makes this circuit exceptional
The Cho La Pass is the geographic and physical centrepiece of the combined circuit — the point where the Gokyo Valley and the Khumbu valley meet at 5,420m. The crossing eliminates all repetition, since the descent is into a completely different valley. Every day moves into new terrain, unlike the Gokyo-only or EBC-only routes.
The Cho La Pass Trek — What the Crossing Actually Involves
The Cho La Pass is the most technically demanding section of the Gokyo Lakes EBC Cho La Pass circuit, and the one most trekkers underestimate when reading about it online. This section deserves honest detail.
Climbing from Gokyo Toward the Pass
The ascent to the Cho La from Gokyo begins at Dragnag village, a 3–4 hour walk from Gokyo across the Ngozumpa Glacier’s lateral moraine. The moraine needs careful footing on unstable rock. Above Dragnag, the trail climbs steeply on rock and glacial ice, and the final 200m to the summit carries snow and ice year-round — microspikes essential from October. Your guide carries the equipment and leads this section.
The summit at 5,420m
The Cho La Pass summit at 5,420m is exposed, cold, and on a clear day one of the finest mountain positions in the Khumbu. Cho Oyu, Gyachung Kang, and Cholatse rise on three sides. The descent ahead into the Khumbu valley drops sharply south toward Dzongla on steep loose scree below the ice line — the guide leads and the group moves together, with no independent pacing here.
Descending to Dzongla
Dzongla sits at 4,830m, a 2–3 hour descent on steep loose terrain. A rocky scree section right at the start requires careful foot placement, and trekking poles are essential throughout. On a standard crossing day, the group arrives at Dzongla in the early afternoon — the crossing day runs 7–9 hours total and is the most demanding day of the combined circuit.
When is the Cho La crossable?
| Season | Months | Pass Condition | Verdict |
|---|---|---|---|
| Autumn | Oct–Nov | Clear, ice on summit section | ✅✅ Best — microspikes sufficient |
| Spring | Mar–May | Variable — snow possible in March | ✅ Good — April best |
| Winter | Dec–Feb | Heavy snow, avalanche risk | ❌ Closed or dangerous |
| Monsoon | Jun–Aug | Unstable, wet rock, poor visibility | ❌ Not recommended |
October is the finest month for the Cho La crossing — stable weather, clear skies, and manageable ice on the summit section. October also gives Gokyo-acclimatised trekkers the best physical baseline for the crossing, which is exactly why October departures should be booked 3–4 months in advance — it’s the busiest Khumbu month.

Lukla Flights — Ramechhap Airport and What to Know
Both the EBC and Gokyo Lakes treks start and end at Lukla, and the flight situation is identical for both. Understanding it before booking saves significant stress.
Ramechhap Airport — how it works in practice
Most Lukla flights in spring (March–May) and autumn (September–November) operate from Ramechhap Airport, not Tribhuvan International Airport in Kathmandu. This isn’t new — Ramechhap has been the primary Lukla departure point during peak season for years. It sits 132 km east of Kathmandu, and the sharing bus or van departs Kathmandu at midnight or 12:30am to reach the airport by 5:00–5:30am for the first morning flight window. Mountain Hike Nepal includes this round-trip sharing transfer in the package price, so you don’t organise it independently — the midnight departure is standard on Day 1 of any Khumbu trek, not a surprise to solve on arrival.
Direct Kathmandu-to-Lukla flights
Direct KTM-to-Lukla flights still operate on a limited schedule, but they book out extremely fast. Availability isn’t guaranteed even with a booking one month in advance during October and November. If you specifically want the direct Kathmandu departure, book at least one month ahead and always confirm the operating airport at the time of booking, since the schedule changes each season and varies by airline.
The 2–3 day buffer rule — non-negotiable
Lukla flights in both directions are weather-dependent. Delays and cancellations happen regularly, particularly at the monsoon transition in late May and during autumn cold fronts in November. Always build 2–3 extra buffer days into your Kathmandu schedule after the trek, and never book a connecting international flight on the same day or the day after your scheduled Lukla return. This is the single most important logistical decision in your entire Khumbu trip planning.

The highest points
Kala Patthar at 5,545m is the highest point of the combined circuit — 188m higher than Gokyo Ri and 181m higher than Everest Base Camp. The circuit also spends one night at Gorakshep at 5,160m, the highest overnight on any standard Nepal trekking route. As a result, the combined circuit demands the most robust acclimatisation schedule of any Everest region itinerary and shouldn’t be rushed at any stage above Namche.
Gokyo Lakes EBC Cho La Pass — Difficulty
The Gokyo Lakes EBC Cho La Pass combined circuit is rated challenging, one grade above the individual Gokyo or EBC routes when taken alone. Three specific elements drive that additional difficulty, none of which the individual routes deliver on their own.
Three Elements That Make This Circuit Harder
First, the Cho La Pass crossing at 5,420m is the most technically demanding section of any standard Nepal trekking itinerary — ice on the summit, loose scree on the descent, and a long 7–9 hour crossing day. The moraine section approaching Dragnag from Gokyo also requires careful navigation on unstable terrain with no marked path. A licensed guide with specific Cho La experience is non-negotiable for this circuit, not a general Everest region guide.
Cumulative altitude exposure
Second, the combined circuit spends more consecutive days above 4,500m than either individual route. Cumulative altitude exposure is a real AMS risk factor, and the route holds altitude above 4,800m for five consecutive nights. Any AMS symptoms in the Gokyo Valley must resolve before the crossing — your guide assesses this on Day 8 morning.
Total distance and physical load
Third, the total distance is 130–140 km over 15 trekking days at high altitude. Daily distances aren’t extreme, typically 12–18 km, but the cumulative load is genuine. The Kala Patthar to Pheriche descent on Day 12 also covers significant altitude loss on steep terrain, which is why 8–10 weeks of uphill walking preparation is the minimum for this circuit.
Best Time for the Cho La Pass Trek
October is the finest month for the Cho La Pass combined circuit. Post-monsoon clarity is at its peak, the pass is crossable without mountaineering equipment, and Kala Patthar sunrise is most reliable.
November is equally excellent — slightly fewer trekkers, colder nights, and the same pass conditions. April is the best spring option, with the pass opening from mid-April and rhododendron adding colour to the lower trail. Avoid December through March — the Cho La carries serious snow and avalanche risk, and winter crossings suit experienced mountaineers only.
Cho La Pass Trek — Combined Circuit Cost
The combined circuit costs more than either individual route due to the additional days and logistics. Contact Mountain Hike Nepal directly for the specific package price for your group size and departure date.

Frequently Asked Questions
On this Cho La Pass trek, the crossing itself at 5,420m is the most technically demanding section of any standard Nepal trekking route. Snow and ice cover the summit section, requiring microspikes or crampons from October through March. Both the moraine approach from Gokyo and the scree descent to Dzongla demand careful footing on unstable terrain. Altogether the crossing day runs 7–9 hours and should only be attempted with a licensed guide with specific Cho La experience, in clear weather.
The recommended direction is Gokyo first, then Cho La Pass, then EBC. This places Gokyo’s lower overnights (4,790m max) before EBC’s higher overnights (5,160m), creating a natural acclimatisation progression. West to east — Gokyo to Dzongla — is also the easier direction, with ice on the ascent rather than the descent. Mountain Hike Nepal runs all combined circuit departures Gokyo-first for acclimatisation and technical safety.
Microspikes are required for the Cho La Pass from October through March — the summit section carries permanent ice that makes trekking boots alone unsafe. Your Mountain Hike Nepal guide carries microspikes for the group and leads the technical section directly. Trekking poles are non-negotiable for the ascent and scree descent, but no ice axes, harnesses, or ropes are needed for the standard crossing with a licensed guide.
