Gokyo, Cho La and Everest Base Camp in one traverse
The Everest Base Camp via Gokyo Lakes and Cho La Pass trek links two of the Khumbu’s best-known high-altitude routes in one demanding traverse. It approaches the turquoise Gokyo lakes through Dole and Machhermo, crosses the Ngozumpa Glacier to Thagnak and then turns east over Cho La to join the main Everest Base Camp trail near Lobuche.
This is a more varied and demanding alternative to the standard Everest Base Camp Trek. Instead of following the same valley on the outward and return journeys, the route explores the quieter western side of the Khumbu before crossing into the upper Everest valley.
Why choose the Gokyo and Cho La route?
The first part of the trek follows the Dudh Koshi towards Namche Bazaar before branching into the Gokyo valley. The trail continues through Dole and Machhermo to the lakeside settlement of Gokyo, with an optional ascent of Gokyo Ri when weather, trail conditions and acclimatisation permit.
From Gokyo, the route crosses rough moraine on the Ngozumpa Glacier to Thagnak. The following stage crosses Cho La, approximately 5,420 m / 17,782 ft, before descending to Dzongla. This high-pass day can involve frozen snow, hard ice, loose rock, steep ground and rapidly changing weather.
After reaching Lobuche, the itinerary continues to Gorak Shep and Everest Base Camp. An optional early ascent of Kala Patthar may be considered in suitable conditions before the descent through Pheriche, Namche Bazaar and Lukla.
Difficulty, acclimatisation and flexibility
This is a strenuous high-altitude trek intended for fit travellers who are comfortable with consecutive walking days, cold conditions, uneven terrain and basic mountain accommodation. Previous multi-day trekking experience is strongly recommended.
The itinerary includes acclimatisation time in Namche and Gokyo, but acclimatisation cannot remove all altitude risk. The ascent profile, individual wellbeing and conditions must be reviewed throughout the journey. Anyone who develops worsening symptoms must not continue to a higher sleeping altitude.
Cho La is never guaranteed. Snow, ice, rockfall, poor visibility, strong wind, illness or insufficient daylight may require the guide to delay the crossing, turn back or use a lower alternative. These decisions are made for safety and must be accepted without pressure to continue.
Mountain-flight and departure planning
Flights to and from Lukla depend on mountain weather, airport conditions and operational restrictions. Flights may operate from Kathmandu or require a road transfer to another operating airport such as Manthali.
The published 17-day itinerary does not provide a fully protected spare day for a prolonged flight disruption. Travellers should keep at least one or two flexible days between the planned return from Lukla and any fixed international flight whenever possible.

Safety and fitness notes
This is a strenuous, remote and high-altitude journey. Travellers sleep above 4,700 m and cross Cho La at approximately 5,420 m. Altitude illness can affect healthy and physically fit people, and fitness does not provide protection against it.
Ascend gradually, report symptoms promptly and never continue to a higher sleeping altitude with symptoms of altitude illness. If symptoms worsen despite rest or treatment, descend when advised by the guide or a medical professional.
The published itinerary is a planning framework. Weather, snow, ice, trail conditions, flight disruption, health and local circumstances may require delay, rerouting, an additional night or early descent.
Every traveller needs insurance that explicitly covers trekking to at least the journey’s maximum altitude, emergency medical treatment, helicopter evacuation where operationally possible, trip interruption and repatriation. Anyone with a relevant medical condition should obtain personalised pre-travel advice from a qualified clinician.
Packing notes
Broken-in waterproof trekking boots; moisture-wicking base layers; insulating mid-layers; warm down or synthetic jacket; waterproof shell jacket and trousers; trekking trousers; warm hat, sun hat and insulated gloves; UV-protective sunglasses suitable for bright snow conditions; high-SPF sunscreen and lip protection; trekking poles; refillable bottles and a personal water-treatment backup; head torch with spare batteries; personal medicines and compact first-aid items; sleeping bag with a suitable comfort rating; duffel and daypack with rain covers; power bank; passport copies; and a small supply of cash.

Your questions, answered
What is the Everest Base Camp via Gokyo Lakes and Cho La Pass trek?
It is a demanding Khumbu traverse that approaches through the Gokyo valley, crosses Cho La to Dzongla and then joins the main trail to Everest Base Camp and optional Kala Patthar.
Does the trek include both Gokyo and Everest Base Camp?
Yes. The itinerary stays at Gokyo, crosses Cho La to the Lobuche side and then visits Everest Base Camp before descending through Pheriche and Namche Bazaar.
Is Cho La a technical climbing pass?
The normal trekking route does not usually require pitched climbing, but it can involve hard snow, ice, steep ground, loose rock and rough moraine. Conditions may require traction equipment or make the crossing unsafe.
Is the Cho La crossing guaranteed?
No. The guide may delay, reverse or reroute the group because of snow, ice, rockfall, poor visibility, strong wind, health concerns or insufficient daylight.
How difficult is this trek?
It is strenuous. Travellers should have good general fitness, be prepared for consecutive long walking days and ideally have previous multi-day trekking experience.
Why is this itinerary longer than the standard Everest Base Camp trek?
Additional days are required for the Gokyo valley, acclimatisation, the Ngozumpa Glacier crossing and Cho La before joining the Everest Base Camp route.
Is Gokyo Ri compulsory?
No. Gokyo Ri is optional and depends on weather, trail conditions, health, acclimatisation and the guide’s assessment.
Is Kala Patthar compulsory?
No. It is an optional early outing based on weather, health, energy and recovery from the previous day’s Everest Base Camp walk.
Can an extra acclimatisation or flight-buffer day be added?
Yes. Additional acclimatisation and flight-contingency days are recommended when the traveller’s schedule and budget permit.
What insurance is required?
The policy must explicitly cover trekking to at least 5,545 m, emergency medical treatment, helicopter evacuation where available, trip interruption and repatriation.
When is the best season for this route?
April–May and October–early November are generally preferred, but Cho La must still be assessed for snow, ice, weather and trail safety before every attempted crossing.
