Langtang is a narrow valley that lies just south of the Tibetan border, and is just north of the Kathmandu valley. It is sandwiched between the main Himalayan range to the north and a slightly lower range of snowy peaks to the south. The area was designated as Nepal's first Himalayan national park in 1971.

This high and isolated region is inhabited by Tamangs whose religious practices, language and dress are much more similar to those of Tibet than to the traditions of their cousins in the Middle Hills. A visit to the Langtang valley offers an opportunity to explore villages, climb small peaks and visit glaciers at a comfortably low elevation.

Though it's close to Kathmandu, the region sees far fewer trekkers than Everest and Annapurna. The trails are challenging with long climbs and descents, often through deep virgin forests or across glacial moraines. Langtang treks offer an experience not found elsewhere.
