Roads and trails leading to the Langtang region will have been affected by the August flood. However, there are alternatives available, including accessing Dhunche and via the Sundarijal-Gosaikunda trekking route.
However please note below that the lower road/trail has been badly damaged and will not be open for use for a long time. However, there is road accessible between Kathmandu, Kalikasthan and Dhunche meaning trekkers are able to access this route. This doesn’t confirm that all trails, bridges and river crossings will be accessible though.
Route Conditions
Route Section | Route Condition | Notes for Trekking
Traditional route (Sybrubesi)| Severe Damage | Not guaranteed safe access
Kathmandu-Kalikasthan-Dhunche| Accessible |Available but confirm road conditions beforehand
Dhunche-Thulo Syabru| Alternative route| Available but confirm conditions on trail and bridges
Sundarijal-Gosaikunda-Thulo Syabru| Alternative route |Available but confirm weather, trails and permits
Here, trekkers may notice that these routes are open however you should always plan your travel carefully. Try to get up-to-date conditions on roads, bridges and trails by contacting local authorities, trekking agencies and guides.
The Langtang Valley was hit hard by this recent flooding event. The Bhotekoshi-Trishuli River flooded on the 26th August causing damage to roads, bridges, trails and buildings around Syabrubesi.
Here, this caused issues with access to the valley from Dhunche-Syabrubesi (road closure). However the Trekking Agencies’ Association of Nepal (TAAN) have confirmed the trekking routes (Langtang, Kyanjin and Gosaikunda) are open.
However, by the 23rd October the Trekking Agencies’ Association of Nepal (TAAN) have stated a new Bailey Bridge was installed at Betrawati restoring partial access back towards Dhunche and Thulo Syabru. Though not all of the trail around Syabrubesi are fully back to normal.
Summary of Effects from the 2026 Langtang Flood.
Road damage – classical route to region impacted via Syabrubesi
Transport and supply issues – difficult to transport goods/resources
Tourism businesses interrupted – lodges, guides, porters and other local tourism business.
Trekking routes - Trekkers can still access but must confirm certain trail sections.
Region opened again – As stated by TAAN in October, 2026, the region are now open. But they do state to continue to take precautions.
Effects of Flood and Current Conditions
Route Section | Current Conditions
Sybrubesi route | Severe damage, Not guaranteed safe access.
Betrawati Bridge | Installed by October 2026.
Access to Dhunche/Thulo Syabru | Opened.
Langtang Village/Kyanjin | Open for trekking.
Gosaikunda | Open (Conditions depend on route and weather).
Importantly, try to always confirm the latest local conditions before travelling to your destination. Heavy rain may impact how safe certain roads, bridges and trails are. Even if your destination is open to trekkers you should still consider whether certain sections will be safe.
Langtang Valley, Kyanjin Gompa and Gosaikunda are currently open (October 2026) according to the Trekking Agency’s Association of Nepal (TAAN).
However, damage caused by the floods in August 2026 have impacted the traditional approach from Syabra besi, trekkers should be aware of the conditions of the trails, bridges and road when trying to reach their destination.
Meanwhile, it has been reported that Trekkers can now go to Dhunche & Thulo Syabru from Kathmandu and onwards to Lama Hotel and the Upper Langtang Valley. Or the alternative route is to go via Sundarijal to Chisapani, Gosaikunda and onto Thulo Syabru. Confirm what routes and places are open.
Langtang Valley Trek Conditions:
Route/Place | Status to Know
Syabru besi approach| Very damaged (Confirm they are closed.)
Dhunche to Thulo Syabru.| This is an alternative route. Cross- check Road, bridge & trail conditions.
Lama Hotel and Upper Langtang Valley| Open to trek, cross-check trail conditions & accommodation.
Sundarijal to Gosaikunda to Thulo Syabru| Alternative trail, have extra time to trek at high altitudes.
Important Considerations:
Check road, bridge conditions with locals & trekking agency.
Hire a professional trekking guide though a local trekking company
Talk to a guide on the land slips, crossings and any alternative routes.
Extra days can be added. Be flexible with your days in case of bad weather, changes in transportation.
Allow yourself to acclimatize slowly. You will need to make sure you have enough time to reach higher points.
Check locally. Conditions can change quickly after heavy rain and during restoration periods.
Although it is reported there is an alternative route to trek the Langtang Valley, you will need to check the conditions of a route section by section. Just because it is announced as being open doesn’t mean all trails to the place are fully restored.
One alternative route for the Langtang Valley Trek is through Dhunche & Thulo Syabru (due to flood damage August 2026). According to the TAAN you can reach Trishuli, Betrawati and onwards to Dhunche or Thulo Syabru via the road. Trek on to Bamboo, Lama Hotel, Langtang Village and Kyanjin Gompa.
In fact, this new Itinerary will not use the traditional route up from Syabra besi. However, you should confirm if the vehicles can be used, trail conditions and accommodations available.

Destination/Section | Approximate Altitude | Average Walking Time
Sundarijal | 1460m | Start of trek
Chisapani | 2165m | 4-6 hours from Sundarijal.
Kutumsang | 2470m | 5-7 hours from Chisapani (depending on route taken)
Thadepati | 3690m | 5-7 hours from Kutumsang
Ghopte | 3430m | 5-7 hours from Thadepati
Gosaikunda Lake | 4380m | 6-8 hours from Ghopte (depending on conditions)

Fitness: You will need to prepare for long walks uphill and downhill and trekking at high altitudes.
Weather: You will likely experience cold nights and snow. The trails can be icy especially around Gosaikunda and Lauribina Pass.
Accommodation: Ensure there is accommodation available and food provided.
Route: Ensure there are bridges, no landslides, the trails will connect and locals can access the trails.
Overall, this trek route is suitable for those with flexible time and who have prepared for high altitudes. The TAAN have noted this is an alternative route but it is important to check the current conditions with locals.
Generally, the Dhunche route to Thulo Syabru is a more direct alternative to getting to the Langtang Valley after the floods in 2026. The Sundarijal-Gosaikunda route will take longer to complete and will require more physical preparation as you will pass through villages in Helambu, alpine lakes and a high mountain pass.
Here, both routes will involve changes in altitude, varying weather conditions and potential issues with the trails. It is important to consider your available days, fitness, budget and current conditions when choosing between the two.

Worst Part | Potential issues with access due to flooding| High altitude, weather and long walking days.
Choosing the Best Option
If you have limited time and have confirmed road and trail access then the Dhunche route could be the best option.
If you want to explore more then the Sundarijal-Gosaikunda route would be best if you have enough days and are fit enough.
Ensure there is accommodation available along the route.
Budget for transport, accommodation, food, guides, permits and any extra nights. Generally the longer route will cost more.
Ensure you have a licensed guide and check recent trail reports.
Overall, the Dhunche route may be the most practical option to get to the Langtang Valley. The Sundarijal-Gosaikunda route will be a longer trek. Both routes will need to be checked for current access and you should be flexible with your days due to the weather, landslides and ongoing repairs.
The August 2026 floods caused a lot of damage to the road going through Trishuli, Betrawati and Syabrubesi. However, the Kathmandu to Kalikasthan to Dhunche road is reported to have been repaired and is accessible.
Here, a Bailey bridge has been built at Betrawati, however this does not mean all roads, bridges and tracks are fully repaired, it is advised you check the full route.
