Everest Base Camp via Gokyo Lakes & Cho La Pass — 18-Day High-Altitude Trek Guide
Trek from the shimmering Gokyo Lakes, cross the steep Cho La Pass and arrive at Everest Base Camp on an 18-day high-altitude route. This guide breaks down what to expect—terrain, culture, logistics and safety essentials—so you can plan with confidence.
The Experience
Before You Go
Prioritize acclimatization
Build in at least two full rest/acclimatization days (Namche and Gokyo) to reduce altitude sickness risk.
Pack for temperature swings
Layering is crucial—mornings can be -15°C on Kala Patthar while daytime hikes warm to single digits; bring a warm down jacket.
Hire experienced guides and porters
The Cho La involves glacier travel and route-finding; a licensed guide plus porter reduces load and increases safety.
Allow buffer days for Lukla flights
Flights to/from Lukla are often delayed; add 2–3 extra days at trip ends to avoid missed international connections.
