The isolated hills and valleys of the western Arunachal Pradesh climb to some of the remotest glaciers and Himalayan peaks blessed with scenic beauty. The multihued culture of the western Arunachal is the result of influence of Bhutan and Tibet which borders this land. Most of the mountains remain completely unknown except the Gori Chen (6858m) and Nyegi Kangsang (7047m). Almost all the mountains here rise up to a height of around 6000 metres high.

The solitary road serving the region runs from Tezpur in Assam through Bhalukpong on the Assamese border to Tawang, ending bone-shakingly high in the mountains at one of Asia`s largest monasteries. On the way you pass through the market town of Bomdila, home up the valley. To the west of the Tawang road lie picturesque Rupa, with its colourful Tibetan monastery; Chillipam, whose monastery and temple offer astounding views and the fascinating Buddhist settlements of Tenzingang and Kalaktang. Beyond tawang and very close to the border of Tibet stretches the lake district of Bangachangsa.
