Why go
Melamchi is a municipality in Sindhupalchok District whose main town, Melamchi Bazaar, sits where the Melamchi river joins the Indrawati, roughly 50-60 km north-east of Kathmandu as the crow flies and about 3-4 hours by road. It is a working market town rather than a sight in itself: buses, jeeps, shops, banks and simple hotels serve the villages of the valley and the Helambu trekking area to the north.
Within the Langtang hub, Melamchi is the practical start or finish point for Helambu treks. Jeeps run from here up dirt roads to Timbu, Tarkeghyang and Sermathang, and trekkers finishing the Helambu circuit usually catch transport back to Kathmandu from the bazaar. The lower valley is warm and subtropical, with rice fields and fruit trees, while the upper valley rises into cool forest and Buddhist Hyolmo villages.
Travellers may also notice the headworks of the Melamchi Water Supply Project upstream, which diverts water from the river through a long tunnel to supply the Kathmandu Valley.
History and culture
The valley is a meeting ground of cultures: Hindu Brahmin, Chhetri and Newar communities dominate the lower settlements, while Tamang and Hyolmo Buddhist villages lie higher up, and the municipality has more than ten Hindu temples and over a dozen monasteries in its watershed. The 2015 earthquake caused heavy damage across Sindhupalchok, including Melamchi.
In June 2021, a landslide dam upstream burst during heavy monsoon rain and sent a debris flood down the Melamchi river that devastated parts of Melamchi Bazaar, killing more than 20 people and destroying homes, roads and bridges; another flood hit upstream villages in July. Much of the bazaar has since been rebuilt and river protection works added, but the valley remains prone to monsoon floods and landslides.

Risks and conditions
Seasonal risks around Melamchi
What this place is typically exposed to, and when. These are seasonal patterns, not a report on conditions now.
Floodinghigh in a typical yearJun-Sep
The Melamchi river carries a documented monsoon flash-flood and debris-flow risk: in June and July 2021 long monsoon rain loosened material upstream, the river was dammed and the breach swept away homes, roads and bridges in the valley.
Landslideshigh in a typical yearJun-Sep
The Araniko Highway corridor runs under extremely steep hillsides that are very prone to landslides, and large slides after heavy rain are a recurring monsoon pattern on this route.
Road blockageshigh in a typical yearJun-Sep
Monsoon slides and washouts on the valley roads into Melamchi can hold up or divert vehicles, and road and bridge damage in the 2021 flood showed how exposed the valley route is.
Coldlow in a typical yearDec-Feb
Winter is mild on the valley floor at about 850 m, though mornings are foggy and the hills above are much colder.

- Mobile data is generally good in town.
- Jeep services to upper villages are shared and leave when full; ask locally for the day's departures.
