Nepal Flood Update and Travel Advisory: Roads, Highways and Trekking Routes: https://mysticadventureholidays.com/contact-us
Updated: 29 August 2026
Nepal is responding to one of its most devastating natural disasters in recent years after a massive flash flood struck the Bhote Koshi River in Rasuwa on the morning of 26 August 2026.
The flood originated near the Nepal–Tibet border and swept through Rasuwagadhi, Timure and Syabrubesi before continuing downstream through the Trishuli and Narayani river systems. Settlements, roads, bridges, hydropower projects and communication networks across Rasuwa, Nuwakot, Dhading and downstream districts suffered extensive damage.
Latest situation
According to reports available as of 29 August 2026:
579 deaths have been confirmed in Nepal
2,381 people remain missing or out of contact
More than 3,700 people have been rescued
Nearly 15,000 security personnel have been mobilised
Thousands of residents, workers, pilgrims and tourists have been affected
Search, rescue, identification and relief operations are continuing. These figures remain provisional and may change as rescue teams reach remote areas and authorities verify missing-person records.
For continuing coverage, see the latest Kantipur updates and the Associated Press situation report.
What caused the flood?
Preliminary scientific assessments indicate that a massive collapse of glacial ice and rock temporarily blocked an upstream river. When this natural barrier failed, it released an enormous surge of water, mud, rocks and debris into the Bhote Koshi River.
Authorities are continuing to monitor newly formed barrier lakes because another sudden release could threaten communities along the Bhote Koshi, Trishuli and Narayani rivers.
Residents, travellers and rescue workers must remain away from riverbanks and low-lying areas and strictly follow official safety warnings.
Roads and highways update
Rasuwagadhi–Kerung border route: The route is severely damaged and remains closed. Travellers must not attempt the Kailash Mansarovar journey through Rasuwagadhi.
Syabrubesi–Rasuwagadhi road: Several sections have been washed away. The road remains closed to regular tourist movement.
Trishuli–Betrawati corridor: This corridor is heavily damaged and unsuitable for normal travel. Several bridges and road sections have been destroyed.
Kathmandu–Dhunche route: Limited access has been restored through an alternative route for light four-wheel-drive vehicles. This is not normal tourist access. Travellers must verify the latest conditions and obtain local approval before departure.
Prithvi Highway: The highway has reopened after mud and debris were cleared around Galchhi, Baireni and Gajuri. However, some sections may operate with single-lane traffic, delays and temporary restrictions.
Kathmandu–Muglin road: The road is operating with restrictions and single-lane traffic in affected sections. Travellers should allow additional journey time.
Malekhu–Dhadingbesi road: Travellers should avoid this route because the Malekhu bridge has collapsed.
Benighat–Arughat route: This is currently the recommended alternative for travellers heading towards Machhakhola or Jagat for the Manaslu Circuit.
The alternative approach to Dhunche currently follows:
Kathmandu–Tokha–Chhahare–Gadbkhar–Aapra–Narja–Lachyang–Saramthali–Patikharka–Bogatitar–Kalikasthan–Dhunche
This route is suitable only for light four-wheel-drive vehicles and should be used only after confirming local conditions.
Although the Prithvi Highway has reopened, travellers should expect slower traffic and possible sudden restrictions while clearing and repair work continues.
Trekking and destination safety status
According to the latest advisory from the Trekking Agencies’ Association of Nepal, most major trekking destinations were not directly affected by the Bhote Koshi–Trishuli flood.
Closed or significantly affected
Kailash Mansarovar via Rasuwagadhi–Kerung: Closed.
Regular road access to Langtang, Kyanjin Valley and Gosaikunda via Trishuli–Betrawati: Affected and closed.
Access to Ganesh Himal and Ruby Valley via Dhunche or Syabrubesi: Affected.
Malekhu–Dhadingbesi approach to Manaslu: Avoid this route because of the collapsed bridge.
Safe destinations with access changes
Langtang, Kyanjin Valley and Gosaikunda: The trekking destinations are considered safe, but their regular road access has been disrupted. TAAN recommends waiting for the usual route to reopen or using the longer Sundarijal–Chisapani–Thadepati–Gosaikunda–Thulosyabru–Langtang approach with professional support.
Ganesh Himal and Ruby Valley: The trekking areas are considered safe. Travellers should approach through Dhadingbesi or Arughat instead of Dhunche or Syabrubesi.
Manaslu Circuit, Tsum Valley, Nubri and Larke Pass: These trekking areas are considered safe. Travellers should use the Benighat–Arughat route to reach Machhakhola or Jagat.
Destinations not directly affected
TAAN reports that the following trekking regions were not directly affected by this particular flood:
Everest region
Annapurna region, including Manang and Mustang
Kanchenjunga
Makalu
Rolwaling
Helambu
Dhaulagiri

Important advice for travellers
Travellers planning to visit Nepal should:
Avoid Rasuwa, Rasuwagadhi, Timure, Syabrubesi and the affected river corridors until authorities confirm that access is safe.
Do not attempt to cross the Nepal–Tibet border through Rasuwagadhi–Kerung.
Check road, weather and trail conditions again on the day of travel.
Include additional road-transfer and itinerary buffer days.
Avoid travelling by road at night during the remaining monsoon period.
Stay away from the Bhote Koshi, Trishuli and Narayani riverbanks.
Travel with a licensed trekking agency and an experienced local guide.
Carry comprehensive travel insurance covering trekking, emergency evacuation and itinerary disruption.
Follow instructions issued by local authorities, Nepal Police, TAAN and the Department of Roads.
Is Nepal safe to visit?
The disaster is catastrophic, but its most severe impact is geographically concentrated around Rasuwa and the Bhote Koshi–Trishuli river corridor.
Most of Nepal’s major tourism regions—including Everest, Annapurna, Mustang, Kanchenjunga and western Nepal—were not directly affected by this flood and remain open to visitors.
However, Nepal’s monsoon season has not yet ended, and weather, road and trail conditions can change quickly. Please plan your journeys using the latest local information, keep your transportation arrangements flexible, and travel with professional support.
Mystic Adventure Holidays continues to monitor official updates and will adjust itineraries whenever necessary to prioritise traveller safety.
