Looking for helplines and contacts? Our flood help center collects the official numbers (Tourist Police 1144, NTB toll-free 1234), embassy links, missing-person channels, and the do/don't list in one place. The government's official rescued-persons list (NDRRMA, in Nepali) is updated as rescue operations proceed.
Update, September 6: the tourist rescue effort has largely succeeded. Of roughly 384 travelers initially reported out of contact, authorities had rescued around 330 foreign nationals by September 1, most from the Gosaikunda and Kailash pilgrimage groups. The wider disaster is graver than first reports suggested: official counts passed 1,290 deaths in Nepal by early September. The Betrawati-Rasuwagadhi road remains damaged along its full 42 km with no confirmed reopening date (limited daytime movement has resumed on some sections for locals and relief), and the Kerung border with the overland Kailash route stays closed indefinitely. One clarification worth knowing: the bungee and rafting river east of Kathmandu shares the Bhote Koshi name but is a different river entirely, and was not affected.
Update, October 13: the Betrawati Bailey bridge over the Phalaku (73 m, per the Kathmandu Post) opened on October 11, restoring the Nuwakot-Rasuwa road link; vehicles can now reach the Betrawati side of the road toward Syabrubesi. Syabrubesi itself still waits on the planned 76 m Bailey bridge over the Bhote Koshi, with no timeline, and there is still no official statement on the Langtang or Gosaikunda trails. Separately, a new flash flood hit the Manaslu side early on October 11: the Budhi Gandaki swept away houses at Jagat Bagar, Salleri, and Ghattikhola and destroyed several suspension bridges plus the Soti and Arughat road bridges. About 97 stranded foreign trekkers were flown out of Jagat, and the Manaslu Conservation Area Project has told trekkers to suspend Tsum Valley trips, describing the lower routes from Machha Khola to Jagat as severely damaged. Treat the Manaslu Circuit as unavailable for new starts until the project confirms a reopening.
Update, October 12: the 74 m Bailey bridge over the Phalaku (Falakhu) river at Betrawati, the Nuwakot-Rasuwa link on the road to Dhunche, was in its final stage on October 9 with only the deck left, and the army was aiming to finish it before Ghatasthapana on October 11; we have not yet seen confirmation that it is open. On October 7 the Department of Roads said transport was expected to reach Dhunche within four to five days, a sign that the road from Kathmandu is still not running normally. Syabrubesi regains road access only once a planned 76 m Bailey bridge over the Bhote Koshi is in place, and the road on to Rasuwagadhi will take longer. There is still no official statement on the Langtang and Gosaikunda trails themselves, and trekking companies' own updates disagree, so get the access route in writing from a registered agency before you travel. On Manaslu, no permanent bridge near Namrung has been confirmed; on the exit side, the Besisahar-Chame road reopened on October 3 after repairs at 35 places, with landslide risk remaining.
Update, October 10: as of early October the road to Syabrubesi itself was still closed. A temporary track reopened the Galchhi to Betrawati section with a Bailey bridge due to follow (over the Phalaku at Betrawati), and a second Bailey bridge over the Bhote Koshi was planned for Syabrubesi, after which the bazaar regains road access; no date had been given. The Dhunche to Thulo Syabru jeep route remains the working way into Langtang, with the caveat that some reports describe the Dhunche road as prioritised for relief traffic, so confirm with your agency the week you travel. Syabrubesi's residents had not yet been able to return.
Update, September 28: operators are now running Langtang Valley treks by private jeep on the Dhunche to Thulo Syabru road, joining the trail near Lama Hotel; the Syabrubesi approach itself remains closed, and the road is weather-sensitive. TAAN has also circulated a walk-in alternative from Sundarijal via Chisapani, Thadepati, and Gosaikunda for trekkers combining the two routes.
Update, September 23: limited road access into Rasuwa has been restored. The Kathmandu-Dhunche road is passable but degraded, and agencies are routing Langtang groups via Dhunche and Thulo Syabru to Lama Hotel rather than through Syabrubesi, whose lower town and the Timure-Rasuwagadhi stretch remain badly damaged; the Langtang trail itself above Lama Hotel was not flooded. Expect 4WD-only sections, slower journeys, and detours, and expect operators to lean toward late-October or later departures, reassessed close to travel. Separately, a September 6 flash flood on the Manaslu Circuit (Therang Khola near Namrung, Gorkha) swept away two bridges, including the Budhi Gandaki suspension bridge; the district administration briefly suspended trekking there, and a temporary wooden bridge plus a detour trail restored movement within days. Confirm both routes with a registered agency before booking.
This is a developing situation. The narrative below reflects reporting as of August 28, 2026, with the updates above as of September 6, 23, and 28 and October 10, 12, and 13. Rely on your embassy, your trekking agency, and official Nepali sources for decisions, and expect numbers and road status to change.
On the morning of August 26, a wall of water came down the Bhote Koshi river through Rasuwa district, the border region north of Kathmandu that is the gateway to the Langtang Valley and the Gosaikunda lakes. The villages of Timure and Syabrubesi - the customs post and trailhead town every Langtang trekker knows - were among the worst hit. Reporting in the days since describes hundreds of people dead or missing across Rasuwa and the downstream districts of Nuwakot, Dhading, and Gorkha, dozens of houses and at least two bridges swept away, and more than ten hydropower projects damaged.
The timing made it a travel story as well as a national tragedy. The Nepal Tourism Board reported around 400 tourists out of contact in the first days - most of them pilgrims headed for Gosaikunda ahead of Janai Purnima (the festival fell on August 28 this year, and the holy lakes draw thousands for it) or crossing toward Kailash Mansarovar through the Rasuwagadhi border point. Indian nationals made up the largest group, alongside travelers from dozens of other countries. "Out of contact" is not a casualty count - communications and roads in the corridor were cut, and many of those listed were expected to be located as networks recovered - but the scale is severe by any measure.
What appears to have happened
Nepal's hydrologists suspect a glacial lake outburst flood (GLOF) on the Tibetan side of the border rather than rain: weather stations near the border recorded little to no rainfall when the surge arrived. A GLOF happens when a lake dammed by glacial ice or moraine fails suddenly, sending its entire volume downstream at once - a mechanism that gives valleys below almost no warning. It is a hazard scientists have warned about across the Himalaya for years as glaciers retreat, and the Bhote Koshi corridor has a history of it. Investigation was ongoing at the time of writing.
What it means for your trip
The essential geography: this is one corridor, not the country. The flood ran down one river system north of Kathmandu. The capital, Pokhara, Chitwan, Lumbini, and the Everest, Annapurna, and Mustang regions are physically untouched, and the autumn season there is proceeding.
- Langtang, Gosaikunda, Helambu (northern approaches): assume disrupted until cleared. Syabrubesi is the road-head for both Langtang and the standard Gosaikunda route, and the access road (the Pasang Lhamu highway) suffered serious damage. Check with a registered agency or TAAN for current status before committing; reopening timelines were unknown at the time of writing.
- The Kailash Mansarovar overland route via Rasuwagadhi: closed by the destruction at Timure. Pilgrims should expect rerouting or postponement and work with their operators.
- Manaslu Circuit: separately, TAAN had already advised trekkers to avoid the Dharapani-Larke Pass trail section after flood damage from heavy rain in early August, including a destroyed suspension bridge near Tilche. A second flood on September 6 near Namrung took out two more bridges; a temporary crossing and detour were in place within days (see the September 23 update above). A third, on the Budhi Gandaki on October 11, wrecked the lower trail between Machha Khola and Jagat (see the October 13 update above). Confirm the route is open before planning an autumn crossing.
- Everything else: unaffected. If your autumn plan was Everest, Gokyo, Annapurna, Mustang, or the cities and safari circuit, there is no flood-related reason to change it.
If Langtang was your plan, the practical move is substitution rather than cancellation - the Annapurna region and the Everest-side valleys absorb the same trip shape, and agencies were already rebooking groups. Nepal's trekking economy runs on autumn; the worst outcome for unaffected regions would be a wave of unnecessary cancellations.
Practical steps for travelers right now
- Worried about someone in the area? The Nepal Tourism Board and the tourist police in Kathmandu run information lines for missing-traveler inquiries, and embassies coordinate lists for their nationals - go through those channels rather than social media rumour.
- Booked through an agency? Contact them before doing anything else - they know current road and trail status faster than news cycles.
- Traveling soon? Register with your embassy in Kathmandu (most offer online registration), keep your itinerary shared with someone at home, and build flexibility into the first days.
- Insurance: check that your policy covers itinerary changes from natural disasters, alongside the standard trekking and evacuation cover.
- In-country now? Stay clear of the affected corridor. Rescue and relief operations need the roads; sightseeing a disaster zone helps no one.
- Monsoon awareness generally: this event was likely glacial rather than monsoonal, but late-August travel in Nepal always means monsoon-season judgment - flexible schedules, morning flights, and respect for river corridors.
How to help
Give money, not goods, and give it through the official channel: the Government of Nepal's Prime Minister's Disaster Relief Fund, the dedicated fund for this disaster, whose donation portal accepts international cards, banking apps, and QR payments, so giving from abroad takes minutes. Skip spontaneous volunteering at the site - untrained arrivals consume the logistics that rescue teams need. And in the months ahead, the most durable help a traveler can offer is the ordinary kind: come, trek the regions that are open, and when Langtang reopens - as it did after 2015, rebuilt largely by its own villagers - be among the first back. That valley has recovered from worse, and its lodges will need the visitors.
