Which Nepal trekking regions are actually open for autumn 2026, and the three that are not

Most of Nepal is open for autumn 2026. On 28 August the Trekking Agencies’ Association of Nepal published a region-by-region access update after the 26 August flash floods on the Trishuli and Bhote Koshi, and it names Kanchenjunga, Makalu, Everest, Rolwaling, Helambu, Annapurna including Manang and Mustang, Dhaulagiri, Dolpa, Rara and Jumla, Humla and the Far West as unaffected. Three areas are not: Langtang and Gosaikunda, Ganesh Himal and Ruby Valley, and the road approach to Manaslu, Tsum Valley and the Larke Pass.

The distinction that matters for your money is this: almost none of the damage is on a trail. It is on the roads that get you to the trail. That is why the Everest region is untouched — you fly in — and why Annapurna, which has more road-accessed trailheads than anywhere else, still comes through clean while Langtang, which has exactly one access road, does not. Our monsoon-withdrawal piece explains why the trail clock runs two to three weeks ahead of the road clock every year.

This was written before the 26 August flood. For the current position, and for the permit, fare and road changes alongside it, see the autumn 2026 Nepal trekking briefing.

Region by region, as of 31 August 2026

The three you cannot walk right now

Langtang and Gosaikunda are the clearest no. The single road into Rasuwa is closed, and we have paused our own Langtang departures rather than sell a trek whose access we cannot verify. If Langtang was your plan, the honest substitute is Helambu, which is the next valley east, is listed as unaffected, and costs less. We set out the full picture in our Langtang access update.

Ganesh Himal and Ruby Valley go with Langtang, because they share the Dhunche and Syabrubesi approach. There is no clever back way in worth paying for.

Manaslu is the one to watch rather than write off. The trail is not the problem — a collapsed bridge on the Malekhu–Dhading Besi road is. Bridges on that corridor get replaced or bypassed with a temporary crossing faster than a washed-out riverside road does, so a mid-October Manaslu start is a different proposition from a mid-September one. Do not book a September Manaslu departure this year without asking, in writing, how your operator plans to get you to the road-head. Our Manaslu flood status page tracks it.

The newest problem is the road to Pokhara

On 30 August, two days after the advisory, the Prithvi Highway subsided at Krishnabhir in Dhading and traffic stopped in both directions. That is the only sealed road between Kathmandu and Pokhara, and it is the road to the Annapurna trailheads and to Chitwan. The trails are fine; the drive is not. The full detail is here, and the practical answer for an Annapurna departure in the next few weeks is to fly Kathmandu–Pokhara instead of driving it.

What this means for your trek

Is it safe to trek in Nepal in autumn 2026 at all?

Yes, in the regions listed as unaffected, which is most of the country. The 26 August floods hit a specific corridor — Rasuwa, the Trishuli valley and the roads that run through it. Everest, the Annapurnas, the far east and the far west were not in it.

Should I wait until later in the season?

If you are flexible, yes. A departure from the second week of October onward avoids both the tail of the monsoon and the repair backlog, and it is Nepal’s most reliable trekking weather anyway — warm days, cold clear nights, the best visibility of the year. If you cannot move your dates, pick a fly-in region.

Will my operator tell me if the route changes?

Ask them to commit to it before you pay. The specific question that works is: “What is the road status on my access route in the week I arrive, and who checks it?” A real answer names a road and a person. A vague one is a warning.
