The Three Passes trek in Nepal's Everest region crosses Kongma La, Cho La and Renjo La in a single loop. People often describe it as a step up from the Everest Base Camp trek, with longer days, more time at altitude and fewer places to turn back. Some trekkers do it as a first Himalayan trek. Others wait until they have a few shorter treks behind them.
