Great Himalayan Trail

The Great Himalayan Trail is a multi-day long-distance route across Nepal’s Himalaya. This route is 1,245.81 km long, gains 61,286 m of elevation, and is classed Extra Difficult, so it is aimed at experienced trekkers rather than casual walkers.

A full walk of the Great Himalayan Trail takes months, not days. Nepal Tourism Board describes the trail as a route that takes months to complete, and a 150-day crossing is often used as a benchmark for the Nepal traverse; on a route of 1,245.81 km with 61,286 m of climbing, exact timing depends heavily on pace, weather, acclimatization, and logistics.

Yes. The Great Himalayan Trail is widely regarded as one of Nepal’s toughest long-distance treks because of its extreme length, sustained altitude, and major cumulative ascent. This route is rated Extra Difficult and packs 61,286 m of elevation gain over 1,245.81 km, which puts it well beyond the level of standard lodge-to-lodge treks.

The Great Himalayan Trail sits at the very top end of trekking difficulty in Nepal. Unlike shorter classic routes, it combines a 1,245.81 km distance with 61,286 m of ascent and prolonged exposure to remote mountain terrain, making it a serious expedition-style undertaking rather than a single-region trek.

Yes. A through-hike on the Great Himalayan Trail typically crosses multiple trekking regions, and Nepal requires permits for trekking, with additional permits for restricted areas issued through the Department of Immigration. Because the route spans a huge section of the country, permit needs vary by segment rather than being covered by one single trail pass.

No. The Great Himalayan Trail is not a beginner hike. With a distance of 1,245.81 km, 61,286 m of climbing, and an Extra Difficult rating, it is better suited to trekkers who already have strong mountain fitness, multi-week trekking experience, and the ability to manage altitude, remoteness, and complex logistics.
