Great Himalayan National Park

Top choice Hiking

in Tirthan Valley

This 754-sq-km park stretches up to the 6000m-plus peaks of the Great Himalaya Range. It is Unesco listed for its remarkable biodiversity but considered a mixed blessing by some locals, notably those whose access to previous subsistence gathering has been curtailed.

Mature forests lower down give way to alpine meadows and high-altitude glaciers. There are plenty of hiking and trekking opportunities here, from easy day walks in a buffer zone (called the Ecozone) to demanding treks into the spectacular upper reaches. Permit rules vary by area.
