Route: Three Passes Trek

The Three Passes Trek in Nepal is in the Everest Region (Sagarmatha National Park) and takes trekkers across three high passes: Kongma La (18,209 ft / 5,550 m), Cho La (17,782 ft / 5,420 m), and Renjo La (17,560 ft / 5,360 m). There's a difference of almost 9400 vertical feet between the high and low points of the hike. Beginning and ending at the Pasang Lhamu memorial gate in Lukla, this route is a loop and regarded as one of the best hikes in the world.
