The Langtang Valley Trek is a 7 to 10 day teahouse trek in the region closest to Kathmandu that follows the Langtang Khola to Kyanjin Gompa at 3,870 m below the 7,227 m Langtang Lirung. A 2026 group departure costs USD 650 to 950 per person including the Langtang National Park permit (NPR 3,000) and a TIMS card (NPR 2,000). It starts with a 7 to 8 hour drive to Syabrubesi rather than a flight, which makes it the lowest-cost classic trek in Nepal, and its optional Tserko Ri climb reaches 4,984 m.
Mingma Tendi Sherpa led the company's first departure back into Langtang after the 2015 earthquake buried the main village, and has tracked the rebuild season by season since, village by village, lodge by lodge. The sections below cover the two permits, a full cost breakdown against the USD 650 to 950 range, the sleeping-altitude schedule and acclimatization plan, what to pack beyond the site's standard list, and the village-by-village rebuild status the guidebooks have not caught up with.
