At a glance
Trip overview
Our 18-day Three High Passes Trek is a complete circuit of the upper Khumbu region, designed for experienced mountaineers and strong trekkers. We cross three distinct high-altitude mountain passes—Kongma La (5,535 m), Cho La (5,420 m), and Renjo La (5,360 m)—while also visiting Everest Base Camp (5,364 m) and climbing Kala Patthar (5,545 m) and Gokyo Ri (5,357 m).
This route is suited only for participants with robust cardiovascular fitness, previous high-altitude experience, and comfort on steep, rocky moraines and occasional ice. We traverse ancient Sherpa trade routes, past the Ngozumpa and Khumbu glaciers, staying in local teahouses managed by Sherpa families in villages such as Thame and Dingboche.
By undertaking the circuit in this sequence, our team ensures proper acclimatisation before each high pass crossing. The walking days are long, frequently ranging from six to eight hours in thin air above 4,000 m, demanding patience, resilience, and steady pacing.

Before you go
Good to know
Altitude & acclimatisation
Our itinerary includes strategic rest and acclimatisation days in Namche Bazaar and Dingboche, plus gradual ascents to high camps. Altitude sickness (AMS) is a genuine risk on this route as three consecutive passes exceed 5,300 m. Our guides carry pulse oximeters and first-aid kits on every departure.
Physical fitness requirements
This is a strenuous, technical trek requiring excellent cardiovascular endurance and prior high-altitude hiking experience. You must be comfortable walking 6 to 9 hours daily over rough moraine, steep stone staircases, and occasional snow or ice.
Teahouse accommodation
Lodges along the Three Passes route are basic and unheated in dining halls. Rooms are twin-share with wooden beds, foam mattresses, and shared facilities. Hot showers and device charging incur small extra fees set by local lodge owners.
Flight delays in Lukla
Mountain weather is notoriously unpredictable. Flights between Kathmandu and Lukla can be delayed or cancelled by low cloud or high winds. We advise adding two buffer days to your international travel schedule to account for potential delays.

Frequently asked questions
What is the maximum altitude reached on this trek?
The highest point on our route is Kala Patthar at 5,545 m, closely followed by the three passes: Kongma La (5,535 m), Cho La (5,420 m), and Renjo La (5,360 m).
Do I need mountaineering experience for the Three Passes?
Technical mountaineering equipment like ice axes and crampons are generally not required, but you must be comfortable walking on steep, rocky moraines, icy sections of Cho La, and exposed ridges.
What happens if my Lukla flight is cancelled?
Mountain flights are weather-dependent. If flights are grounded, we will wait for the next available slot or arrange a chartered helicopter if conditions permit and you opt to cover the charter cost.
How heavy should my daypack be?
Carry only your essentials—water bottles, rain shell, warm layers, camera, and valuables—weighing around 5 kg to 7 kg. Our porters carry the main duffel bags.
Is drinking water safe along the trail?
Teahouses sell boiled water or bottled mineral water. Alternatively, we recommend carrying purification tablets or a UV purifier to treat local tap water.
What is the group size for your departures?
We operate both solo custom trips and small group departures, typically capped at 10 participants to ensure safety and personalised attention from our guides.
