Doon Valley, Dehradun, Uttarakhand

The Doon Valley is an unusually wide, long valley within the Sivalik Hills in the Lower Himalayas, in the state of Uttarakhand, India. Within the valley lies the city of Dehradun, the capital of Uttarakhand state.

The Doon valley lies between two intermittent ranges of the Himalayas. It is bounded on all sides by mountains, with one range running from the west to the east (with Mussorie at the centre) in a semi-circular arc; and one running at the south from Poanta Sahib to Haridwar. The valley also forms a watershed between the Yamuna and Ganges river systems. In fact the Yamuna and Ganges are closest to each other as they pass the Doon valley, with the Yamuna forming the western boundary and the Ganges the east.
