Clasificación de seguridad
Best: October–November and March–May, 'cold at higher elevation' (NTB, Langtang page). December–February: heavy snow above Langtang village and around Kyanjin Gompa; Tserko Ri (~4,984 m) may be unsafe. June–September monsoon: the steep Langtang Khola gorge trail is landslide-prone — not a safe window.
- ▲Altitude illness — fast profile: Syabrubesi (~1,500 m) to Kyanjin Gompa (3,870 m) in 2–3 days, Tserko Ri ~4,984 m; NTB: life-threatening above 2,500 m, 300–500 m/day sleeping-altitude limit
- ▲Landslide and rockfall zones on the steep gorge trail, worst in and after the monsoon
- ▲Avalanche paths cross the upper valley — the trail passes the 2015 earthquake avalanche site at Langtang village
- ▲Winter snow and cold above Kyanjin Gompa
Guide is a legal requirement: NTB's Revised TIMS Provision (31 Mar 2023) names the 'Langtang Trek' among routes where trekkers must be accompanied by a licensed guide and carry an agency-issued TIMS card (NPR 2,000); no exception found, and Langtang National Park entry (NPR 3,000 foreigners) is also required. Historical context not on the agency pages fetched: the April 2015 earthquake triggered an avalanche that destroyed Langtang village and killed roughly 300 people; the rebuilt trail crosses that debris zone, and the gorge terrain that produced it is unchanged. Do not day-hike Tserko Ri without an acclimatization day at Kyanjin.
