Nepal Trekking After the Rasuwa Floods: Current Trail Status (Updated September 2026)
If you're planning an autumn trek in Nepal, you've probably seen the headlines about flooding in Rasuwa district and wondered what it means for your trip. The short answer: most of Nepal's trekking routes are completely unaffected, and autumn 2026 is still shaping up to be a great season to visit. Here's the full, current picture.
Two Flood Events, One River Corridor
On the morning of August 26, 2026, a large ice and rock avalanche broke away from the Langtang Himal at high altitude and collapsed into the Lhende Khola, mobilizing into a fast-moving debris flow. It swept down through the Bhote Koshi and into the Trishuli River system, devastating Syabrubesi, Timure, and other communities along the Rasuwa corridor, and severely damaging roads and bridges as far downstream as Betrawati and Malekhu. It was one of the most severe flood events the region has seen in decades, and our hearts remain with the communities and families affected.
Roughly three weeks later, in mid-to-late September, a second flash flood struck the same Rasuwa corridor, again sending a surge of water, sediment, and boulders through the Bhote Koshi and Trishuli systems. Scientists are still assessing whether this second event, like the first, originated from an ice-rock avalanche at high altitude. It has reinforced the caution already in place around the Rasuwa–Bhote Koshi–Trishuli corridor and pushed back the realistic timeline for road repairs in the area.
The key thing to understand: both events are confined to one specific river corridor in northern Nepal. They have not affected the country's other major trekking regions, which continue to operate normally.
Current Trail Status by Region
Region | Status | Notes |
Everest Base Camp / Khumbu | ✅ Open, unaffected | Drains into the Dudh Koshi, an entirely separate river system. Flights, trails, and teahouses operating normally. |
Annapurna (Base Camp, Circuit, Mardi Himal) | ✅ Open, unaffected | Drains into the Marsyangdi and Kali Gandaki. Some minor, unrelated monsoon road detours near ABC, cleared quickly. |
Manaslu Circuit | ✅ Open, unaffected | Drains into the Budhi Gandaki. Road access via the usual Kathmandu–Arughat route is functioning. |
Upper Mustang | ✅ Open, unaffected | Well outside the affected watershed; flights and jeep routes operating as normal. |
Langtang Valley & Gosaikunda | ⚠️ Access disrupted | Trekking trails themselves are largely intact, but the usual road approach through Syabrubesi is badly damaged. An alternative route via Dhunche is being used, adding roughly one to two extra days. |
Tamang Heritage Trail / Ganesh Himal / Ruby Valley | ⚠️ Access disrupted | Same Rasuwa corridor issue — approach roads affected, route-specific planning needed. |
Our honest assessment: given the second flood event, we expect the Langtang and Gosaikunda corridor to need into October, and possibly later, before road access normalizes. We're not going to give you a firm reopening date because, frankly, nobody can guarantee one right now — but we're watching it closely and will update this page as things change.
What Our Guides and Office Are Seeing
We've kept in close contact with our guide network and local contacts throughout the Kathmandu Valley and along the affected corridor since the first flood struck. A few things worth passing on:
Our guides confirm that the disruption is genuinely localized to the Rasuwa–Bhote Koshi–Trishuli corridor. Teams currently on the trail in Everest, Annapurna, and Manaslu have reported no impact whatsoever on trail conditions, teahouse availability, or logistics.
"People hear 'Nepal floods' and assume the whole country is affected — it isn't. I was on the Annapurna Circuit the week after the first flood and everything was completely normal," says Saroj Ghimire, Director of Global Nepal Treks.
Road crews and the Nepal Army have made steady progress on emergency repairs in Rasuwa, but the second flood set that timeline back. We're treating any specific reopening estimate with caution until we see it confirmed on the ground.
As always, our team follows Global Nepal Treks' standard safety protocol: no group is routed through an active-risk corridor, regardless of how eager anyone is to keep an itinerary on schedule.
What This Means If You Have a Booking With Us
If you're booked on Everest Base Camp, Annapurna, Manaslu, Upper Mustang, or a helicopter tour: your trip is unaffected. Proceed as planned.
If you're booked on Langtang, Gosaikunda, or the Tamang Heritage Trail: please get in touch with us directly. We're handling these on a case-by-case basis with two options:
Flexible rescheduling — we'll move your trek to later in the season, or to spring 2027, at no rebooking penalty.
Switching to an alternative route — many travelers with Langtang bookings have opted to switch to Manaslu or Annapurna instead, and we can usually accommodate this with minimal itinerary changes.
If you hold travel insurance, we'd recommend checking whether your policy covers itinerary changes due to natural disaster or government-advised route closures — most standard adventure-travel policies do, but it's worth confirming with your provider directly rather than assuming.
The Bottom Line
Nepal is open for trekking this autumn. A serious, localized disaster struck one river corridor in Rasuwa, and it deserves to be reported accurately rather than exaggerated into a nationwide closure. Everest Base Camp, the Annapurna region, Manaslu, and Upper Mustang are all running normally, with October and November shaping up to be an excellent window as usual.
If you'd like to talk through your options — whether that's booking an EBC or Annapurna trek for this season, or adjusting an existing Langtang booking — get in touch with our team and we'll walk you through it honestly, based on what we're actually seeing on the ground.
