尋找 Langtang 健行夥伴

On 26 August 2026 a large rock-and-ice collapse from the north face of Langtang Lirung sent a debris flow down the Lhende Khola into the Bhote Koshi and Trishuli rivers, hitting Rasuwagadhi, Timure, Syabrubesi and Betrawati (ICIMOD). Many bridges and long stretches of the Pasang Lhamu Highway were damaged, and a large number of people died or are missing; reported figures differ by source.

What operators and local reports say (checked 19 October 2026):

• Syabrubesi, the usual Langtang road-head, is reported destroyed or closed as a trekking gateway, with the bridge to it swept away; restoration depends on the Betrawati highway reopening.
• The Trishuli Bazaar-Betrawati-Dhunche road was reported still closed for repair as of 21 September. A light-vehicle track has reopened, and agencies projected the remaining gaps passable no earlier than mid-October; that is a projection, not an official date.
• A reported alternative is to drive to Dhunche and walk via Thulo Syabru to Lama Hotel and Langtang. On 16 October local residents reported repairing the landslide-damaged trail sections above Paljor and below Rimiche.
• ICIMOD warns that loose debris in the valley can be remobilised by monsoon rain.
• A 23 September Met Office request that trekkers suspend Himalayan treks was reported; check whether it still applies.
• Helambu (walked from Sundarijal) is not on the Trishuli corridor, and no source we found reports damage there.

Do not plan an itinerary that starts or ends at Syabrubesi until it is confirmed open. We found no official reopening notice. Check current road and trail conditions with Langtang National Park and your trekking agency before booking, and do not rely on this summary alone.
