KATHMANDU: Nepal's monsoon season has intensified sharply, forcing authorities to suspend night-time travel on several major highways and issue emergency advisories across tourist-heavy corridors — developments that directly affect travellers, trekkers and tour operators planning movement across the country this weekend.

Gandaki Province: Eight districts under night travel ban

The most sweeping restrictions cover Gandaki Province, where night-time vehicular movement has been suspended across eight districts — Kaski, Gorkha, Lamjung, Syangja, Tanahun, Baglung, Parbat and Myagdi — following forecasts of heavy rainfall on July 19 and 20 from the Department of Hydrology and Meteorology.

The National Disaster Risk Reduction and Management Authority warned of possible landslides, flash floods and inundation in vulnerable areas and placed all disaster-response mechanisms on standby. Transport services connecting Kaski — home to Pokhara, Nepal's second-largest tourism hub — with neighbouring districts will remain halted at night for two days. Trekkers and travellers headed to the Annapurna, Manaslu and Dhaulagiri regions, all accessed via these districts, are advised to confirm route status before departing.

Kathmandu–Hetauda corridor under advisory

The District Administration Office in Makwanpur has issued a travel advisory covering road links connecting Hetauda with Kathmandu, Chitwan, Lalitpur and Sindhuli, warning of heavy to very heavy rainfall in Bagmati Province with heightened risk of floods, landslides, road erosion and debris flows.

Vehicles travelling from Hetauda to Kathmandu via Deurali will be stopped at Chaukitol from Saturday evening until 5 am Sunday. Vehicles heading to Lalitpur via the Kanti Highway will be halted at Chaughada from 6 pm Saturday. Travellers have been advised to avoid non-essential journeys, particularly at night and during continuous rainfall, and to stay away from flooded roads, bridges and riverbanks.

Multiple highways blocked or restricted

Several key routes are either fully blocked or under time-based restrictions. The Khurkot–Nepalthok–Katunjebesi section of the BP Highway linking Kavrepalanchok and Sindhuli is closed to all vehicles daily from 6 pm to 4 am until further notice, though daytime traffic remains open. The Kanti Lokpath is similarly barred to all vehicles between 5 pm and 5 am.

The Araniko Highway in Sindhupalchok — the primary road link to the Tibet border — has been shut following landslides and debris flows at Jirokilo and Kodari in Bhotekoshi Rural Municipality, a critical route for cross-border trade and adventure travel. The Kaligandaki Corridor in Baglung has been blocked by a landslide at Belbagar in Jaimini Municipality-8, disrupting access to the Mustang and Dolpo regions.

The Saljhandi–Dhorpatan road in Arghakhanchi is blocked after rocks fell at Dhungekhola, and the Mechi Highway in Ilam has been disrupted after the road surface turned muddy at Rajduwali in Ilam Municipality-9.

In Kavrepalanchok, multiple landslides at Ghumaune, Gimdi, Biruwadanda and Pinthali in Roshi Rural Municipality have severely disrupted traffic on sections of the BP Highway.

Advisory for travellers and operators

Authorities have urged the public to monitor official updates and refrain from non-essential travel, particularly after dark and during periods of continuous rainfall. Tour operators and trekking agencies are advised to check route conditions with district administration offices before dispatching clients and to build contingency days into itineraries given the likelihood of further disruption as monsoon activity intensifies through the coming week.
