Three High Passes trek in Nepal

Planet

The Khumbu belongs equally to the mountains, the Sherpa communities who live among them, and the wildlife that calls this landscape home. Our job is to connect trekkers with all three while leaving no trace behind. That balance only works if everyone on the trail takes responsibility for it.
Litter is non-negotiable. We educate our guides and porters on environmental practice from day one, and we extend the same expectation to every trekker. Having a support team does not mean your waste becomes their problem. Designated waste collection points exist along the trail — use them. For water, Sagarmatha National Park has clean spring water sources throughout the route; your guide will point out where to refill your bottle. Buying single-use plastic water bottles when clean alternatives are available is unnecessary and avoidable.
Power in this region runs entirely on solar energy. Every tea house, lodge, and guesthouse on the route uses solar panels — there is no grid connection above Lukla. If you want reliable charging for personal devices, bring a small personal solar panel. Clear skies are common during both the spring and autumn trekking windows, so it works.
This is a walking tour from start to finish. We fly Kathmandu–Lukla–Kathmandu (35 minutes each way) rather than the two-day bus option specifically because the environmental cost of that road journey is significant. No vehicles are involved once your boots hit the Lukla trail.
Parts of the route pass through protected habitat where yak, Himalayan tahr, snow leopard, and high-altitude bird species are present. If you encounter wildlife, maintain distance, stay quiet, and do not offer food. These animals are not accustomed to human interaction and should not become so. You are a guest in their habitat.
The Three High Passes circuit is a serious loop, not a tourist corridor. Much of it — particularly the Renjo La approach and the Bhote Koshi descent — sees far fewer trekkers than the main Everest Base Camp trail. Stay on marked paths and follow your guide's lead at all times. The Cho La crossing includes a glaciated section at the col that can be icy and unstable; treat it with the same respect you give any mountain terrain.

People

The Khumbu is Sherpa territory. The Sherpa people are an ethnic group indigenous to this high-altitude region, and their physiological adaptation to altitude, combined with generations of route knowledge, makes them the most qualified guides anywhere in the Himalaya. Every guide on this trek is a Sherpa. That is not a marketing choice — it is the only choice that makes sense here.
Porter's employment matters too. A porter's income is seasonal and directly tied to trekking traffic. Hiring one is not a convenience; it is a concrete economic contribution to a local family. We ask that you do not decline the porter service. Beyond wages, tipping is entirely at your discretion, but if your team has looked after you well, it is the most direct way to show it.
On your acclimatization day in Namche Bazaar, the route passes through Khumjung village, where the Hillary School stands as one of the more enduring legacies of the 1953 Everest expedition. Sir Edmund Hillary, who with Tenzing Norgay Sherpa completed the first confirmed ascent of Everest on 29 May 1953, later established the Himalayan Trust, which went on to fund over 60 schools across remote Nepal. The Khumjung school is among the best-resourced in the country as a result.
The visit is observational, not a volunteering session. We schedule it for the afternoon, after classes finish, so there is no disruption to the school day. Entry into the building is not permitted, but teachers are sometimes available for a conversation in the yard. The point is simple: to see what access to education looks like in a mountain community that has had significant outside support, and to understand what it still looks like in communities that have not.
Swotah runs scholarship support for students in more remote, less-visited areas of Nepal where that support has not reached. If this is something you want to learn more about or contribute to after the trek, ask your guide — or look at our Millennium Homestay Trek, where we work directly with the Newari community in eastern Nepal.
