Gokyo Lakes Trek
A less-crowded alternative to EBC in the same region. Trek to the stunning turquoise Gokyo Lakes and climb Gokyo Ri for views of four 8,000m peaks including Everest, Lhotse, Makalu, and Cho Oyu.

A compact but rewarding trek through the Langtang Valley - the "Valley of Glaciers." Close to Kathmandu with rich Tamang culture, yak cheese, and stunning mountain views.
Tilicho Lake Trek
Trek to Tilicho Lake (4,919m) - one of the highest lakes in the world, nestled in a dramatic amphitheatre of towering cliffs and glaciers in the Annapurna region. The trail follows the classic Annapurna Circuit route through diverse landscapes from subtropical forests to arid high-altitude terrain.
