Nepal's Monsoon Is Still Cutting Roads to Annapurna, Manaslu and Langtang — Here's When Each Trail Clears for Autumn 2026
This week floods severed the access roads to Manang and Rasuwa, and landslides remain a fixture on the Manaslu trailhead road. We checked conditions region by region and worked out when trekkers can actually expect firm, dry trails this autumn.
As of this week, Nepal's monsoon is still actively cutting the roads trekkers use to reach some of its most popular trailheads. On 29 July 2026, the Besisahar-Chyame-Manang road in Lamjung, the access route for the Annapurna Circuit, was reported completely blocked by landslides, and the Pasang Lhamu Highway into Rasuwa, the road every Langtang trekker drives to reach Syabrubesi, was completely blocked at Khalte in Rasuwa (Kathmandu Post; Khabarhub, 29 July 2026). Neither closure is unusual for late July. Both are a reminder that “post-monsoon” is still a few weeks away, even as autumn bookings fill up.
Key facts, this week
- Besisahar-Chyame-Manang road (Annapurna Circuit access): blocked by landslide
- Pasang Lhamu Highway, Rasuwa (Langtang access): blocked, Trishuli River damage
- Nine highways nationwide reported disrupted by floods and landslides in the past fortnight
- Nepal's average monsoon withdrawal date: 2 October (Department of Hydrology and Meteorology)
The good news is that road damage and trail conditions are two different clocks, and the trail clock moves faster. Once the rain itself eases, typically two to three weeks ahead of the roads being fully repaired, trails firm up, leeches disappear and river crossings drop to safe levels well before every access road is back to its dry-season state. Here is where each of the four regions actually stands.
Region by region
| Region | Current issue | Typically clear by |
|---|---|---|
| Annapurna (Circuit / ABC) | Besisahar-Manang road landslide; Beni-Jomsom road also hit near Rupse, Myagdi | mid-late Sept |
| Manaslu | Arughat-Soti Khola-Jagat corridor, a recurring monsoon landslide zone; sections rerouted since 2025 | mid-late Sept |
| Langtang | Pasang Lhamu Highway to Rasuwa cut by Trishuli River damage | early-mid Sept |
| Everest (Khumbu) | Reached by air, not road, so largely unaffected; lower Solu trail still muddy | late Sept |
Annapurna sees the widest exposure simply because it has the most road-accessed trailheads: this week's damage sits on the Manang side (Besisahar-Chyame) and the Mustang side (Beni-Jomsom, hit near Rupse in Myagdi district), while the Ghandruk and Poon Hill trailheads out of Pokhara are largely unaffected. Manaslu's access road between Arughat and Jagat is a known yearly landslide zone. Operators rerouted sections of the trail between Yaru Bagar and Deng after the 2025 monsoon, and a road-building project along the Budhi Gandaki has shifted the lower valley route again this year, so early-autumn parties should expect a still-evolving road rather than the finished version. Langtang's single access road, the Pasang Lhamu Highway through Trishuli and Dhunche, is the most exposed to river damage of the four because it runs directly alongside the Trishuli River for long stretches, but it is also usually the fastest to reopen once flows drop, since it typically suffers washouts rather than permanent bridge failures. Everest is the outlier in the best way: because trekkers fly to Lukla rather than drive in, road damage elsewhere in the country barely touches the Khumbu itinerary at all.
What this means for trekkers
What this means for your trip
If you are booking an early-September start on the Annapurna Circuit, Manaslu or Langtang, build one extra buffer day into the road transfer specifically, not just the flight, and ask your operator for a same-week road-status check rather than relying on an itinerary written months ago. Anything booked from mid-to-late September onward is booking into Nepal's most reliable trekking weather of the year: warm days, cold clear nights and the year's best mountain visibility, and by then this week's damage is very likely to be routine seasonal repair rather than an active closure.
None of this is unusual, and none of it should put off an autumn booking. Nepal repairs the same handful of vulnerable road sections every single monsoon, on a schedule the Department of Roads knows well: 155 excavators are already deployed nationwide with 122 more on standby. What it does mean is that a trek booked for the first half of September carries a real, if manageable, chance of a road delay that a trek booked from late September onward does not.
We track all four of these regions directly through our own guide network on the ground, and can flag current trail status for the Manaslu Circuit, Langtang Valley or Annapurna Circuit before you book. See also our running road-conditions tracker for the latest closures nationwide.
