Quick answer: As of September 9, 2026, the Manaslu Circuit Trek, Manaslu Tsum Valley Trek, and Larkya La Pass remain officially suspended by Nepal’s District Administration Office (DAO) in Gorkha, following a September 6 flash flood that destroyed two bridges near Namrung. This blog will cover: Is the Manaslu Circuit Trek Open? and Alternative trekking destination which are open. However, field reports indicate residents have already built a temporary wooden bridge and bypass trail, restoring basic pedestrian and mule access even though the formal government suspension has not yet been lifted. In practical terms: the trail is passable on the ground, but it is not yet officially reopened, and trekking companies cannot lawfully or safely send clients through until DAO Gorkha inspects the crossing and issues a new notice.
Here is a case where the situation on the ground and the official status are different:
| Status Type | Current Situation |
|---|---|
| Official DAO Gorkha suspension | Still in effect; no formal notice has been issued lifting it. |
| Physical trail access | A temporary wooden bridge and new bypass trail reportedly built by residents are functional. |
| Guided commercial trekking | Not authorized to resume until DAO Gorkha formally inspects and reopens the route. |
| Local and resident movement | Reportedly using the new pedestrian/mule crossing already. |
According to the field update on 9th September 2026 from a local resident, a team of roughly 30 residents organized under the ward chairperson has constructed a temporary wooden bridge along with a new section of trail bypassing the destroyed crossing. But the District Administration Office hasn’t published a notice regarding this.
The closure was caused due to a flash flood struck at the Therang Khola in Namrung, Chumnubri Rural Municipality Ward 4, at around 3:30 AM on September 6, 2026. According to the source, The debris had temporarily dammed rhe Therang Stream near its source and blocked the river and collected water surged downstream all once into Namrung.
| Detail | Information |
|---|---|
| Date of flood | September 6, 2026, approx. 3:30 a.m. |
| Location | Therang Khola, Namrung, Chumnubri Rural Municipality-4, Gorkha |
| Cause | Debris dam burst on the Therang Stream, releasing a sudden surge. |
| Bridges destroyed | Iron bridge (Wards 2–4) + main suspension bridge over the Budhi Gandaki |
| Other damage | 4 homes destroyed, 2 micro-hydropower plants knocked out |
| Casualties | None reported; residents reached higher ground in time. |
| Authorities involved | District Administration Office (Gorkha), Manaslu Conservation Area Project (MCAP) |
The most significant development since the initial closure is the community led temporary bridge effort. Rather than waiting for a full engineered rebuild, local resident mobilized directly:
No official reopening date has been announced. Reopening for commercial trekking purposes depends on:
| Trek | Status | Why It’s a Good Manaslu Alternative |
|---|---|---|
| Annapurna Circuit Trek | Open | Closest match in style — a full circuit trek with a high pass crossing (Thorong La, 5,416 m), on a separate river system. |
| Annapurna Base Camp Trek | Open | Shorter alternative with dramatic high-altitude scenery, unaffected by either 2026 flood. |
| Everest Base Camp Trek | Open | Sits in a different watershed entirely (Khumbu), untouched by both the Rasuwa and Manaslu floods. |
| Upper Mustang Trek | Open | Rain-shadow region, largely unaffected by monsoon-related flooding. |
| Langtang Valley Trek | Affected (separate closure) | Impacted by the earlier August 26 Rasuwa flood; confirm status separately before booking. |
Officially, no — the District Administration Office’s suspension remains in effect. On the ground, a community-built temporary wooden bridge and bypass trail reportedly restored basic pedestrian and mule access, but this hasn’t been formally inspected or approved for commercial trekking.
Field reports indicate a group of roughly 30 local residents, organized by the local ward president, built the temporary wooden bridge and cut a new bypass trail around the damaged section.
Not through a licensed agency at this time. The crossing has not been officially inspected or approved by DAO Gorkha, so commercial trekking remains suspended regardless of the community bridge’s existence.
No. These are two separate events on two different river systems — the Rasuwa flood struck the Bhote Koshi and Trishuli corridor on August 26, while the Manaslu flood struck the Budhi Gandaki and Therang rivers on September 6.
