About Doon Valley
The Doon Valley is a bizarrely wide, long valley inside the Shivalik Hills in the Lesser Himalayas, in the conditions of Uttarakhand, Himachal Pradesh and Haryana India. Inside the valley lies the city of Dehradun, the capital of Uttarakhand state. Doon or Dun is a nearby word for valley, especially an open valley in the Shivaliks or between the Shivaliks and higher Himalayan lower regions. Different valleys in this locale have names like Patli Dun, Kothri Dun, Pinjore Dun in Himachal. Such valleys are named Inner Terai in Nepal.
The Doon valley lies between two discontinuous scopes of the Himalayas. It is limited on all sides by mountains, with northern range running from Kalsi in the west to Muni Ki Reti in the east with Mussorie at the middle in a semi-round circular segment; and southern range running at south from Paonta Sahib in the west to Haridwar in the east.
