Deadly Flooding in Nepal and Tibet Prompts Tour Operators to Shift Plans

Devastating flooding in Nepal this week has left at least 168 people dead and more than 1,300 missing across the Himalayan region following a catastrophic glacier collapse.

The floods started on Wednesday morning when a high-altitude Himalayan glacier collapsed, sending rocks and debris crashing down into the Lhende Khola and Bhotekoshi river valleys. This created a sudden rush of water, mud, and ice that rushed through communities near the Nepal-Tibet border.

According to the Associated Press, the disaster has left at least 165 dead and 826 people missing in Nepal, and 3 dead and 558 missing in Tibet, totaling more than 1,300 unaccounted for—including many foreign tourists, both Americans and Canadians, and pilgrims. Videos from the scene showed entire villages, multi-story buildings, and infrastructure swept away or severely damaged.

The region is known as the “Valley of Glaciers” and is surrounded by towering Himalayan peaks, including Langtang Lirung and Yala Peak. It has become a popular trekking hub that is less commercialized than the Everest or Annapurna regions, featuring routes like the Langtang Valley Trek, the Tamang Heritage Trail, and the path up to Gosainkunda Lake.

For North Americans, some of the more popular operators, like Insight Vacations, aren’t currently operating in Nepal. And others, like Intrepid, Explore Worldwide, and Abercrombie and Kent, did not have any travelers in the area at the time of the flooding.

Yalamber Raj, GM of Nepal for Intrepid Travel, told TMR that of the itineraries that Nepal operates in the region, just two—the Tamang Heritage and Langtang Valley Trek and Tibet: Beijing to Kathmandu Overland—pass through the affected region. Neither was operating at the time, but the damage from the flooding will force Intrepid to change plans in the future.

“The Tamang Heritage and Langtang Valley Trek itinerary includes an overnight stay in Syabrubesi village, which has suffered significant damage and is likely to affect future departures,” he said.

“The safety of our customers, staff, and host communities remains our highest priority… We will adapt our operations as needed to ensure the safety of our customers and team members. We are also focused on supporting the wellbeing of our local partners and host communities and are exploring ways we can assist those affected as they navigate the challenges ahead,” he added.

G Adventures did have one group in Tibet, and the tour operator told TMR that all travelers in that group, along with its staff, are safe and accounted for. G Adventures is adjusting the itinerary of that group because of changes to the border crossing, but all other itineraries in the region remain unchanged.

“Our local operations teams are monitoring the situation closely and are in regular contact with our travelers and local partners, with further adjustments to itineraries to be made if required,” it said to TMR.
