Nepal Flood Crisis Disrupts Tourism Routes as Pasang Lhamu Highway Closes and Key Roads Face Travel Restrictions

Flooding and landslides have blocked major routes to Nepal’s tourism destinations, especially the Pasang Lhamu Highway, with other routes restricting their use and causing damage to other major roads in September 2026. The Nepal Police have alerted the public after the monsoon season caused the rivers to overflow, land to slip, and eat away at the banks of other rivers. This impacted major road routes connecting Kathmandu to the rest of the country and caused problems for people wanting to transport goods to various regions and people wishing to travel to mountain resort areas.

The roads affected by the monsoon season carry most of the tourism infrastructure to and from the Himalayan regions. These roads also offer vital access to the neighboring countries for local residents, and support trekking and other activities. Until the roads are fully repaired and monitored by the authorities, they will restrict usage.

Flood Damage Blocks Pasang Lhamu Highway, Affecting Access to Rasuwa and Langtang Region

The Pasang Lhamu Highway, one of Nepal’s most important northern road connections, has been completely blocked due to flood damage and river erosion. The highway connects Kathmandu with Rasuwa district and Syabrubesi, serving as a major gateway for travellers heading towards the Langtang region, Himalayan trekking areas and the Rasuwagadhi border point with China.

Severe erosion caused by swollen rivers damaged sections of the highway, cutting off normal vehicle movement. The route has been particularly affected around areas near the Trishuli River corridor, where floodwaters damaged road sections and forced authorities to consider alternative access arrangements.

The closure has significant implications for tourism because many international and domestic visitors rely on road transfers from Kathmandu before beginning trekking journeys in northern Nepal. Destinations around Syabrubesi, Dhunche and Langtang National Park depend heavily on road accessibility, making highway conditions a key factor for travel planning.

Key Impact of Pasang Lhamu Highway Closure

The closure also affects local businesses, supply transportation and communities that depend on regular highway access for essential goods and services.

BP Highway Operates Under Strict Time-Based Traffic Controls

The BP Highway, an important transport route connecting Kathmandu Valley with eastern Nepal, continues to operate under controlled conditions following flood and landslide risks. According to the latest Nepal Police advisory, the Khurkot–Nepalthok–Katunjebesi section of the highway is operating under specific time schedules to reduce safety risks. Freight and cargo vehicles weighing up to 10 tonnes are permitted to operate during night hours from 7:00 PM to 5:00 AM, while private and public passenger vehicles are allowed during daytime hours between 4:00 AM and 6:00 PM, depending on road conditions.

The restrictions have been introduced because several sections remain vulnerable to flooding, erosion and landslides. Nepal’s mountainous geography makes highways particularly exposed during periods of intense rainfall, with sudden slope failures and debris flows capable of blocking roads without warning. For tourism operators, the controlled movement means journey schedules between Kathmandu and eastern destinations may require additional planning. Travellers using road transport should confirm operating hours before beginning long-distance journeys.

Tokha–Chhahare Road Becomes Critical Alternative Route Under Restrictions

The Tokha–Chhahare road, which links Kathmandu with northern areas, is also facing operational restrictions due to landslide risks. Traffic movement has been limited at vulnerable sections, with authorities restricting travel during high-risk periods. The route has gained importance as an alternative connection after damage to sections of the Pasang Lhamu Highway affected direct access towards Rasuwa.

Authorities have imposed restrictions at certain locations, including sections where landslide risks remain high. Vehicles are being managed carefully to prevent accidents caused by unstable slopes, falling debris and damaged road surfaces. The route plays an important role in maintaining connectivity between Kathmandu and northern districts when primary highways experience disruption.

Multiple Nepal Transport Corridors Continue Facing Flood and Landslide Risks

The latest highway disruptions are part of a wider transport challenge caused by extreme weather conditions across Nepal. Heavy rainfall, river erosion and landslides have affected multiple highways and local roads, particularly in mountainous districts.

Recent disruptions have affected areas including:

• Rasuwa – major highways affected by flood damage and erosion.
• Nuwakot – road sections impacted by landslides and flooding.
• Dhading – highway movement affected by landslide incidents.
• Kavre and Sindhuli – controlled operations introduced on vulnerable sections.

Nepal’s road network remains highly dependent on mountain corridors that pass through steep landscapes. During periods of heavy rainfall, even operational routes can experience sudden restrictions due to changing ground conditions.

Travel Impact on Nepal Tourism and Visitor Movement

Nepal remains a major destination for adventure tourism, trekking, cultural experiences and mountain exploration. However, road disruptions can influence travel plans, particularly for visitors heading towards remote destinations.

Travellers planning journeys through affected areas should consider:

Before travelling

• Check updated road conditions with local authorities and transport providers.
• Confirm whether highways are operating during planned travel hours.
• Allow extra time for road journeys.
• Prepare alternative travel arrangements where possible.

For trekking visitors

• Confirm road access before travelling towards trekking gateways.
• Coordinate transfers with local operators.
• Expect possible delays due to weather-related disruptions.

For transport operators

• Follow traffic schedules issued by authorities.
• Avoid restricted travel periods.
• Monitor weather developments before dispatching vehicles.

Current Road Status Overview

Authorities Continue Restoration and Safety Monitoring

The Police and other concerned agencies are conducting road and traffic management and assessing damages along the affected routes. Roads are being cleared and repaired. Re-opening of roads, however, will depend on the condition of the damaged sections as well as the weather.

Reliable roads from Kathmandu to other places in the hills and mountains is important for the tourism industry, as most places of interest to visitors are located off the capital. The difficulties being faced by travelers on different routes because of the recent weather conditions demonstrate how unpredictable routes to the mountains of Nepal can be and the importance of planning trips considering the various risks. Since there is heavy flood water and other obstructions on roads in Northern and Western Nepal, travelers are encouraged to be flexible with their plans and to be aware of the latest traffic situation.
