At the border of Great Himalayan National Park at 4500 fts. Above sea level. The Tirthan Valley in Kullu District is one of the most beautiful places in Himachal Pradesh. Located within the Great Himalayan National Park, the 'pucca' road winds its way lazily along the river through forests and past fields and tiny hamlets with quaint names like Chalogi, Mungla, Nagini, Ghushaini ..... Numerous paths lead off the road to the snow fed river itself as it gushes its way over the rocks to drop into pools and spread itself out over flats where every stone is visible through its crystal clear waters, home to the wilder brown trout and its more coveted cousin, the rainbow trout.
Tirthan Valley is home to the Great Himalayan National Park (GHNP).
