Great Himalayan National Park was constituted in 1984 and was formally notified as a national park in 1999. It is located in Banjaar Sub-Division of Kullu District of Himachal Pradesh, India, in the far Western Himalayas. GHNP is one of the most recent additions to a huge network of wildlife reserves found in Himalayan region in India and adjoining countries.
Perched at an altitude of over 1600 meters above sea level, the riverside retreat of Tirthan is an adventure-centric getaway blessed with a wealth of nature's treasures. Located in the Kullu district of Himachal Pradesh, Tirthan Valley derives its name from the Tirthan river, which winds its way through it. Tirthan is an offbeat destination that has something for everyone. This quiet valley is ideal for trekking, fishing, wildlife watching, and discovering under-explored hill villages.
