Information checked: 31 August 2026
This guide reflects information available on 31 August 2026. If your journey passes through an affected
area, confirm your route and access before travelling.
A trekking route is never just a trail. In Nepal, it passes through people's homes, villages, livelihoods and
everyday lives—which is why a disaster in the mountains is never only a travel disruption.
On 26 August 2026, a catastrophic flood swept through the Bhote Koshi–Trishuli river corridor, destroying
settlements, roads, bridges and infrastructure along its path.
As of the morning of August 31, government figures reported 903 deaths and 4,247 people still
unaccounted for. Behind those numbers are families and communities dealing with enormous loss.
Our thoughts at Global Eco Trails are first with them.
The short answer is that the disaster is severe, but its direct impact is concentrated along a particular river
corridor. Nepal's trekking regions have not all been affected in the same way.
| Area | What travelers should know |
| Langtang & Gosaikunda | The destinations were not reported as directly devastated, but normal access through Rasuwa, Syabrubesi and Dhunche has been seriously disrupted. |
| Everest / Khumbu | Not directly affected by this flood. Normal mountain weather and Lukla flight conditions still apply. |
| Annapurna / Manang / Mustang | Not directly affected. Road travel between Kathmandu and Pokhara is a separate issue because of major highway damage. |
| Manaslu / Tsum Valley | Not directly affected, but some road approaches may need to change. |
| Rasuwagadhi / Kerung / Kailash | Severely affected. The normal border route is disrupted/closed. |
Other trekking areas not reported as directly affected include Kanchenjunga, Makalu, Rolwaling, Helambu,
Dhaulagiri, Dolpa, Rara/Jumla, Humla and several Far-West routes.
“Not directly affected” does not mean risk-free. Nepal is still in the monsoon, so rainfall, landslides, road closures and changing mountain weather can cause problems elsewhere too.
On August 26, a destructive surge of water, rock, ice and debris travelled through the Lhende Khola–Bhote
Koshi–Trishuli river system.
The event was initially widely described as a Glacial Lake Outburst Flood (GLOF). Later assessments by
Nepali scientists pointed towards a more complex sequence involving an ice-and-rock collapse high in the
mountains, temporary river blockage and the sudden release of accumulated water.
The full mechanism is still being studied, so here we simply refer to it as the Bhote Koshi–Trishuli flood
disaster.
Lhende Khola → Bhote Koshi → Trishuli
The badly affected corridor includes areas around Rasuwagadhi, Timure, Syabrubesi, Betrawati and
communities farther downstream along the Trishuli system.
Everest is not Rasuwa. Annapurna is not Rasuwagadhi. Mustang is in another part of Nepal altogether.
Images from one devastated part of the country do not describe conditions everywhere else.
What Does This Mean for Popular Trekking Routes?
Langtang & Gosaikunda: The Main Problem Is Access
This is where much of the confusion lies.
TAAN reported Langtang/Kyanjin Valley and Gosaikunda as outside the direct flood damage, but normal
access through the Rasuwa side has been badly affected.
For Langtang, the usual journey towards the trailhead depends on roads around Syabrubesi and Rasuwa.
For Gosaikunda, the usual Dhunche-side access has also been disrupted.
If either trek is in your plans, don't rely on the transport arrangement in an itinerary
prepared before August 26. Check how you will actually reach—or leave—the trail before
travelling.
Everest, Annapurna & Manaslu
For these major trekking regions, the picture is much simpler.
Everest/Khumbu, Annapurna, Manang and Mustang were not reported as directly affected by this flood.
Manaslu, Tsum Valley and the Nubri–Larke area were also listed outside the direct flood impact, although
road approaches towards Manaslu may need adjustment.
So if your trip is to Everest Base Camp, Gokyo, Annapurna Base Camp, Annapurna Circuit, Mardi Himal,
Upper Mustang or another geographically separate trek, the destruction seen around Rasuwa should not
be assumed to represent conditions on your trail.
Normal seasonal risks still apply.
Going to Pokhara? The Road Is the Issue
Pokhara and the Annapurna trekking region were not directly struck by this flood. The usual road journey
from Kathmandu, however, has a serious problem.
At Krishnabhir in Dhading, part of the Muglin–Kathmandu road collapsed after erosion from the Trishuli
River, stopping normal traffic through that section.
This is not expected to be a short closure. After inspecting the site, Dhading District Police estimated that it
could take at least a month to restore traffic. This is an estimate rather than a confirmed reopening date, as
the Department of Roads is still carrying out its technical assessment.
Alternative connections through Gorkha are being used or considered for travel between Kathmandu,
Pokhara and western Nepal.
Global Eco Trails | Nepal Flood August 2026 Travel Guide
If Pokhara or Annapurna is part of your trip, allow extra time and confirm how your transport is being
arranged.
Your destination may be unaffected, while the normal road journey to reach it is not.
Rasuwagadhi, Kerung & Kailash
The Rasuwagadhi–Kerung corridor is among the areas seriously affected.
TAAN reported the usual Kailash Mansarovar route through Rasuwagadhi/Kerung as closed and advised
operators to consider alternative arrangements.
If your trip includes Tibet or Kailash Mansarovar, speak directly with your operator before travelling. Another
border crossing cannot simply be swapped in at the last minute. Permits, transport arrangements and
border operations all need to line up.
Should You Cancel Your Nepal Trek?
Not automatically.
If your journey passes through Rasuwa, Syabrubesi, Langtang or Gosaikunda access routes, the flood-
affected Trishuli corridor or Rasuwagadhi–Kerung, expect changes.
If you're travelling to Everest, Annapurna, Mustang, Kanchenjunga, Makalu, Dolpa or another region
outside the direct flood corridor, this particular disaster alone does not mean your trek has been cancelled.
Before deciding, ask yourself two things:
Where am I going? How am I getting there?
The second question matters just as much as the first.
Before You Travel
Confirm your exact access route rather than only checking whether the trekking destination is open. Allow
extra time for detours, follow local guides and authorities if conditions change, and never pressure a driver
or guide to use a route they consider unsafe.
Please also avoid entering badly affected communities simply to see or photograph the destruction.
Nepal remains in the monsoon, so places untouched by this particular flood can still experience rain,
landslides and transport delays.

The Himalaya Is Not Empty
Global Eco Trails | Nepal Flood August 2026 Travel Guide
A teahouse supports a family. A bridge connects a village. The road taking us to a trailhead is somebody
else's everyday road.
That is worth remembering now.
Do not make one devastated part of Nepal sound like the whole country has been
destroyed. But don't minimise what happened simply because your own trail remains
open.
Understand where the disaster happened. Know where it did not. Listen to local guidance and leave room
for plans to change.
Because every route on our trekking maps is somebody else's home.
Global Eco Trails is a Nepal-based trekking and travel company. If you already have a Nepal journey planned and are unsure
how the flood has affected your route, contact us to check your itinerary and current access.
