Trekking in The Three Passes
Nepal
Eighteen days in the Khumbu taking the high circuit rather than the base camp highway.

Sarek is Europe's last true wilderness, and it makes no concessions: no marked trails, no huts, no bridges over its powerful glacial rivers, and no phone signal to call for help. Two hundred peaks and a hundred glaciers sit inside a park with essentially no infrastructure, and to cross it you carry everything, ford your own rivers and navigate by map and compass.
The rivers are the crux. Fed by melting glaciers, they run cold and strong, and a single crossing can mean scouting, waiting for the lower flows of morning, or losing a day to conditions. The reward is Rapadalen — a vast braided valley that, in early September, turns red and gold for a brief window before the snow, with the mosquitoes finally gone.
The feasible season is short, roughly late July to early September. This is the one on the list that will genuinely test you: come with real wilderness experience, full self-sufficiency, and respect for country that offers no safety net at all.
In season: Jul–Sep
No permit, but also no rescue infrastructure. Autumn colour peaks for a narrow window in early September.

The high route in summer — Orla Perć's chains and ladders, then Rysy and the top of Poland at 2,499 m.

Ten days around a compact range of 6,000 m peaks, crossing eight passes above 4,600 m.
