The Gokyo Lakes EBC Cho La Pass trek is a 16-day circuit that combines the Gokyo Valley, the Cho La Pass at 5,420m, and Everest Base Camp into one route — no backtracking between the two valleys. It’s the most complete way to see the Everest region in a single trip: five turquoise lakes, Gokyo Ri’s panorama, a genuine high-altitude pass crossing, and Base Camp itself, all without repeating a day’s walking.

Gokyo Lakes EBC Cho La Pass — Route Overview
The 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, then crossing the Cho La east into the Khumbu. From there it continues to Everest Base Camp and Kala Patthar before descending back 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 → Gorak Shep → Everest Base Camp (5,364m) → Kala Patthar (5,644m) → Pheriche → Namche Bazaar → Phakding → Lukla
What makes this circuit different
The Cho La Pass is the geographic centrepiece of the combined circuit — the point where the Gokyo Valley and the Khumbu valley meet at 5,420m. Crossing it removes the repetition you’d get from doing Gokyo and EBC as two separate out-and-back trips, since the descent drops into a completely different valley. Every day moves into new terrain.
The Cho La Pass — What the Crossing Actually Involves
The Cho La Pass is the most technically demanding section of this circuit, and the part most trekkers underestimate before they see it in person. It deserves honest detail rather than a passing mention.
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 are essential from October onward. Your guide carries the equipment and leads this section.
The summit at 5,420m
The Cho La Pass summit sits at 5,420m — exposed, cold, and on a clear day one of the finest mountain positions in the Khumbu, with Cho Oyu, Gyachung Kang, and Cholatse rising on three sides. The descent ahead drops sharply south into the Khumbu valley toward Dzongla, on steep loose scree below the ice line. Your guide leads and the group moves together here — this isn’t a section for independent pacing.
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 demands careful foot placement, and trekking poles are essential the whole way down. On a standard crossing day the group reaches Dzongla by early afternoon — the full crossing runs 7–9 hours and is the hardest single day on 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 best month for the Cho La crossing — stable weather, clear skies, and manageable ice on the summit section. It also gives Gokyo-acclimatised trekkers the strongest physical baseline for the crossing, which is exactly why October departures need to be booked 3–4 months ahead — it’s the busiest month in the Khumbu.

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 — this combined circuit is no different. Understanding it before you book saves real stress later.
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 132km east of Kathmandu, and the shared 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. We include this round-trip shared transfer in the package price, so you don’t need to organise it yourself — 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 fast. Availability isn’t guaranteed even a month ahead during October and November. If you specifically want the direct Kathmandu departure, book at least a month in advance and confirm the operating airport at the time of booking — 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. 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 planning this trip.

The highest points
Kala Patthar at 5,644m is the highest point of the combined circuit — 287m higher than Gokyo Ri and 280m higher than Everest Base Camp itself. The circuit also spends one night at Gorak Shep (5,164m), the highest overnight stop on any standard Nepal trekking route. Between that and the Cho La crossing, this combined circuit demands the most careful acclimatisation schedule of any Everest region itinerary — nothing above Namche should be rushed.
Gokyo Lakes EBC Cho La Pass — Difficulty
This combined circuit is rated challenging — one grade above the individual Gokyo or EBC routes taken alone. Three things drive that added difficulty, none of which the standalone routes deliver on their own.
The Cho La crossing itself
The Cho La Pass 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 approach to Dragnag from Gokyo also needs 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
The combined circuit spends more consecutive days above 4,500m than either individual route — five consecutive nights above 4,800m. That cumulative exposure is a genuine AMS risk factor, not just a longer trek. Any AMS symptoms in the Gokyo Valley need to resolve before the crossing; your guide assesses this on the morning of Day 8.
Total distance and physical load
The total distance runs roughly 130–140km over 15 trekking days at high altitude. Daily distances aren’t extreme, typically 12–18km, but the cumulative load adds up. The Kala Patthar-to-Pheriche descent on Day 12 also covers significant altitude loss on steep terrain in one push. Eight to ten weeks of uphill walking preparation is the realistic minimum for this circuit, more than the 6–8 weeks that’s enough for EBC or Gokyo alone.
Best Time for the Combined Circuit
October is the best month for this circuit. Post-monsoon clarity is at its peak, the Cho La is crossable without mountaineering equipment, and Kala Patthar sunrise views are at their most reliable.
November is nearly as good — slightly fewer trekkers, colder nights, and the same pass conditions. April is the strongest spring option, with the pass opening from mid-April and rhododendron colouring the lower trail. Avoid December through March: the Cho La carries serious snow and avalanche risk in that window, and a winter crossing suits experienced mountaineers only, not a standard guided trek.
Cost of the Combined Circuit
The combined circuit costs more than either individual route, since it adds four extra days and the technical logistics of the Cho La crossing. Contact us directly for the exact package price for your group size and departure date — the figures below are for comparison against the two standalone routes.
| Route | Duration | Package (2–4 pax) | Total budget estimate |
|---|---|---|---|
| Gokyo Lakes only | 11 days | from $1,149 | $1,650–$2,700 |
| EBC only | 12 days | from $1,259 | $2,000–$2,450 |
| Gokyo + EBC via Cho La | 16 days | Contact us for exact pricing | $2,600–$3,200 |

Frequently Asked Questions
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. The crossing day runs 7–9 hours and should only be attempted with a licensed guide who has specific Cho La experience, in clear weather.
Gokyo first, then the Cho La, then EBC. This places Gokyo’s lower overnights (4,750m max) before EBC’s higher overnight at Gorak Shep (5,164m), 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. We run every combined-circuit departure Gokyo-first, for both acclimatisation and technical safety.
Microspikes are required from October through March — the summit section carries permanent ice that makes trekking boots alone unsafe. Your 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.
