What Trekkers Need to Know Before Visiting Nepal
Updated: August 28, 2026
The devastating flash floods that struck northern Nepal on August 26, 2026, have understandably raised questions among international travellers:
Is Nepal still safe for trekking? Which trekking regions were affected? Where can travellers go, and which areas should currently be avoided?
The answer requires some important context.
Nepal is a large Himalayan country, and the recent disaster has not affected all trekking regions equally. The catastrophic flooding was concentrated around the Bhotekoshi and Trishuli river systems and the Nepal–Tibet border area, while many of Nepal's most popular trekking destinations remain unaffected.
According to the latest information from the Trekking Agencies' Association of Nepal (TAAN), several major trekking regions—including Everest, Annapurna, Manaslu, Kanchenjunga, Makalu, Dolpo, Mustang and Dhaulagiri—remain safe from the direct impact of the recent floods.
However, access conditions can change quickly during the monsoon season, so travellers should always check the latest road and trail conditions before departure.
What Happened in Nepal?
On August 26, a catastrophic Himalayan event triggered a massive flash flood affecting the Bhotekoshi and Trishuli river systems.
The disaster caused extensive damage to roads, bridges, settlements and infrastructure, particularly in northern areas close to the Nepal–China border.
The affected region includes parts of Rasuwa and Nuwakot, with major disruption around the Bhotekoshi and Trishuli corridors. Rescue and recovery operations are continuing, and authorities are still monitoring additional flood risks.
This is a serious disaster, and travellers should not attempt to enter affected areas simply because a trekking route appears open on a map.
Areas Currently Affected or Requiring Extra Caution
🔴 Rasuwa – Bhotekoshi – Trishuli Corridor
This is the primary area affected by the recent disaster.
The Rasuwa/Bhotekoshi and Trishuli corridors have experienced major damage, and some roads and access routes remain closed or restricted because of the disaster and ongoing rescue operations.
🔴 Rasuwagadhi / Kerung – Kailash Route
The Kailash Mansarovar route through Rasuwagadhi/Kerung is currently closed and severely affected.
Travellers planning a Kailash pilgrimage should not attempt to use this route until authorities confirm reopening. Alternative arrangements may be required.
🟠 Dhunche / Syabrubesi Access
The traditional access routes toward parts of the Langtang and Gosaikunda region have been affected.
The important distinction is:
The trekking destinations themselves may remain safe, while the road access to them may not be.
TAAN currently reports Langtang/Kyanjin Valley and Gosaikunda as safe, but access through the Trishuli–Betambeti corridor has been affected.
For this reason, travellers should not assume that the normal Kathmandu–Dhunche–Syabrubesi road is available.
🟢 Trekking Regions Reported Safe From the Direct Flood Impact
According to the latest TAAN route safety update, many major trekking regions remain unaffected by the August 26 disaster.
🏔️ Everest Region
Everest Base Camp, Gokyo and other Khumbu trekking routes remain among the major trekking options that were not directly affected by the flood.
The Everest region is geographically separated from the Bhotekoshi–Trishuli disaster corridor.
Possible treks include:
- Everest Base Camp
- Gokyo Valley
- Everest View Trek
- Three Passes Trek
- Mera Peak
- Khumbu Valley trekking
🏔️ Annapurna Region
The Annapurna region, including Manang and Mustang, remains reported as unaffected by the direct impact of the recent floods.
Popular options include:
- Annapurna Base Camp
- Annapurna Circuit
- Mardi Himal
- Poon Hill
- Khopra Ridge
- Manang
- Mustang
Recent reports also confirmed that trekkers around Annapurna Base Camp were safe following the disaster.
However, because August is still monsoon season, individual roads and trails should be checked immediately before departure.
🏔️ Manaslu Region
Manaslu remains one of the important trekking alternatives.
TAAN reports that the Manaslu region, including Tsum Valley and the Nubri–Larke Pass area, remains safe from the direct flood impact.
There is, however, an important access consideration.
Travellers heading toward Machha Khola and Jagat should avoid the Malekhu–Dhadingbesi route because of bridge damage and instead use the Benighat–Arughat route, subject to current road conditions.
For autumn 2026, Manaslu remains an important trekking option, but access should be confirmed before every departure.
🏔️ Mustang
Upper Mustang and Lower Mustang remain outside the direct impact area identified by TAAN.
Mustang is particularly attractive as a trekking destination because of its rain-shadow landscape.
Popular journeys include:
- Upper Mustang Trek
- Jomsom
- Lo Manthang
- Muktinath
- Lower Mustang
🏔️ Kanchenjunga
The far eastern Kanchenjunga region remains unaffected by the recent flood disaster according to TAAN.
This remote region offers spectacular high-Himalayan trekking away from the affected northern-central corridors.
🏔️ Makalu
The Makalu region has also remained outside the direct impact of the recent floods.
Makalu Base Camp is therefore another option for experienced trekkers, subject to normal monsoon and trail-condition checks.
🏔️ Dhaulagiri
The Dhaulagiri region has not been directly affected by the August 26 flood disaster according to the latest TAAN assessment.
Because this is a remote and demanding trekking area, experienced guides and careful weather monitoring remain essential.
🏔️ Dolpo
Dolpo remains unaffected by the direct flood impact.
Upper Dolpo and Lower Dolpo offer remote Himalayan landscapes and are geographically far from the main disaster corridor.
🏔️ Rara, Jumla, Humla and Far-West Nepal
TAAN also reports the following regions as unaffected by the recent floods:
- Rara
- Jumla
- Humla
- Saipal
- Khaptad
- Badimalika
- Api Himal
These areas are geographically distant from the primary Bhotekoshi–Trishuli disaster zone.
What About Langtang?
This is one of the most important questions for travellers.
Langtang Valley itself is reported as safe, but the traditional access route has been affected.
TAAN currently reports that the Langtang/Kyanjin Valley remains safe, while access through the Trishuli–Betambeti corridor is closed/affected.
Alternative trekking access has been suggested through:
Kathmandu → Sundarijal → Chisapani → Thadepati → Ghopte → Gosaikunda → Thulosyabru → Pairo → Lama Hotel → Langtang → Kyanjin
Travellers should only use alternative routes after confirming current conditions with a registered trekking agency and local authorities.
What Should Trekkers Avoid Right Now?
Until authorities confirm that conditions have stabilized, travellers should avoid:
❌ The Bhotekoshi flood-affected corridor
❌ Rasuwagadhi/Kerung border route
❌ Damaged sections of the Trishuli corridor
❌ Entering Rasuwa disaster zones without official clearance
❌ Roads and bridges currently closed by authorities
❌ Unverified alternative roads
❌ Trekking alone in affected regions
❌ Crossing swollen rivers or damaged bridges
The situation remains dynamic, and some roads may be closed temporarily for rescue and recovery operations.
So, Is Nepal Safe for Trekking?
Yes—but travellers must choose their destination carefully.
It would be misleading to say that the whole of Nepal is unsafe because of one regional disaster.
At the same time, it would also be irresponsible to say that everywhere in Nepal is completely safe while rescue operations and monsoon hazards continue.
The correct message is:
Nepal remains open for trekking, but travellers should avoid affected areas, choose routes based on the latest local information, and travel with professional support.
Nepal's trekking regions are spread across a huge Himalayan landscape. A flood affecting one river system does not automatically mean that trekking routes hundreds of kilometres away are affected.
