What Happened During the Rasuwa Flood?

On the day of Wednesday, August 26, 2026, around 8:40 AM, Nepal’s Rasuwa region witnessed a devastating flood that can barely be imagined. The Bhote Khoshi and Trishuli river systems were affected by an unanticipated flash flood believed to have happened due to glacial collapse in the bordering area of Tibet and Nepal.

This flood severely affected daily lives and route connectivity in the Bhote-Koshi and Trishuli river corridors. The Rasuwa-Keyrung border, Rasuwa, Nuwakot, Dhading, Gorkha, and Tanahun districts were too impacted due to the rise in water level.

The scale of damage has created challenges in rescue operation, transportation, and infrastructure access in several regions. The Rasuwa flood has also impacted the trekking and tourism activities in the Langtang region of Nepal.

Which Trekking Routes Of Nepal Were Affected?

The most significant impact has been on Rasuwa and the Langtang region. The information about affected trekking routes of Nepal due to the Rasuwa flood is provided below:

Trekking Region	Safety Status	Overview
Everest Region	Generally Safe	The Everest region lies in a different geographic location and is open for trekking. But trekkers are advised to check for flights and weather conditions before trekking.
Annapurna Region	Generally Safe	Annapurna region treks like the Annapurna Base Camp, Annapurna Circuit Trek, Ghorepani Poon Hill Trek, and Mardi Himal Trek are fully operational and not affected by the Rasuwa flood.

Alternative Route To The Langtang Region Trek

It is important to note that trekking to the Langtang region is affected by the Rasuwa flood if you choose the Nuwakot-Rasuwa route. But the region can still be accessed from alternative routes, which may take additional days in trekking. You can access the Langtang region via trekking from Kathmandu and Sundarijal and head towards Chisapani, Kutumsang, Tharepati, Ghopte, and Gosaikunda. From Gosaikunda you can head to Thulo Syabru and then reach Pairo/Lama Hotel.

However, it is important to confirm the route condition from authorities and experienced trekking operators before preparing for trekking via an alternative route. Also, although alternative routes to the Langtang region are available, choosing an unaffected region like the Annapurna or Everest region can be safer.

Safety Tips for Trekking in Nepal After the Flood

Yet again, precautions are always the best option to maximize your safety during a visit. Some of the important safety tips you should follow when trekking in Nepal after a flood are provided below:

If you are planning to trek in regions that are unaffected by Rasuwa floods, such as the Everest region, the Annapurna region, the Mustang region, and the Dolpo region, you don't necessarily need to cancel your tour to Nepal. But if you have plans to trek in the Langtang region, such as the Gosaikunda trek, the Langtang Valley trek, and the Tamang Heritage Trek, you can choose safe and alternative destinations in Nepal.

As Nepal is severely affected by the Rasuwa flood, Nepal requires help and support. And giving continuity to tourism activities can help the country to continue at its pace.

Conclusion

The Rasuwa flood in northern Nepal has caused severe damage and loss of human lives, infrastructures, and disconnected access to the Rasuwa-Langtang region from the main road routes. But Nepal is not entirely closed, as flood-affected regions are completely safe, as they are geographically separated from the Rasuwa flood-affected area.

If you are planning to visit Nepal for adventure activities like trekking, we suggest taking informed decisions by being careful when choosing destinations. Checking the latest route conditions, verification of destination details from authorities, and travel with expert guides and tour operators are suggested.
