Though the formation of the Indian sub-continent is among the oldest in the world, the Himalaya mountains are among the youngest. A geologist can present conclusive proof that the Himalaya were once at the bottom of the ocean.

The Himalaya have attracted geologists, geographers, Trekkers and lovers of nature. They have a strange fascination for artists, poets, photographers and mystics. They are a paradise for Trekkers and mountaineers and are the cradle of thousands of rivers, streams and glaciers.

The Himalaya extend over 2500 km in east-west and between 250 to 425 km in north- south direction. The most extraordinary thing about Himalaya is the way they have been formed in three parallel ranges known as Great Himalaya, the Lesser or the Central Himalaya and the Outer or the Siwalik Himalayas. Commencing at Nanga Parbat in the north-west, these reanges pass through Pakistan, Jammu and Kashmir, Himachal Pradesh, Garhwal, Kumaon, Nepal, Sikkim, Bhutan and Arunachal Pradesh.
