The Doon Valley is an unusually wide, long valley within the Sivalik Hills and the Lesser Himalayas, in the Indian states of Uttarakhand, Himachal Pradesh and Haryana. Within the valley lies the city of Dehradun, the winter capital of Uttarakhand state.
The Doon Valley lies between two intermittent ranges of the Himalayas, the Outer Himalayas (a.k.a. the Siwalik Hills) and the Lesser Himalayas, known locally as the Mussoorie Range. It is bounded on all sides by mountains, with northern range running from Kalsi in the west to Muni Ki Reti in the east with Mussoorie at the centre in a semi-circular arc; and southern range running at south from Paonta Sahib in the west to Haridwar in the east. 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. It runs 75 km long from west to east.
The Doon Valley is ecologically rich, particularly with regard to birdlife, with over 500 bird species having been recorded within the valley and in the surrounding areas, including the Mussoorie Hills and Rajaji National Park. The Reserved Forests and community forests in the region, in and around the valley are also botanically rich in terms of hardwood deciduous forests (esp. Sal or Shorea robusta, and Teak), flowering and fruiting trees, natural wetlands, and Terai and Bhabar ecosystems. Several rivers (e.g. Song, Tons, Suswa, Jakhan, Rispana and Asan) and a number of lesser streams flow through the valley, having their sources in either the Mussoorie Hills or the Sivalik Hills; all local rivers ultimately flow into either the Ganges or the Yamuna. Other than Rajaji National Park, the local protected areas include Asan Barrage Conservation Reserve and Jhilmil Jheel Conservation Reserve, with the 1000-acre campus of the Forest Research Institute in Dehradun representing another Important Bird Area (IBA).
Rajaji National Park, Kalesar National Park and Jaunsar-Bawar region adjoin the valley as well.

The Yamuna is the second-largest tributary river of the Ganges by discharge and the longest tributary in India. Originating from the Yamunotri Glacier at a height of about 4,500 m (14,800 ft) on the southwestern slopes of Bandarpunch peaks of the Lower Himalaya in Uttarakhand, it travels 1,376 kilometres (855 mi) and has a drainage system of 366,223 square kilometres (141,399 sq mi), 40.2% of the entire Ganges Basin. It merges with the Ganges at Triveni Sangam, Prayagraj, which is a site of the Kumbh Mela, a Hindu festival held every 12 years.

The Indian Himalayan Region is the section of the Himalayas within the Republic of India, spanning thirteen Indian states and union territories, namely Ladakh, Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, West Bengal, Manipur, Meghalaya, Mizoram, Nagaland, Tripura, Assam, and Arunachal Pradesh. The region is responsible for providing water to a large part of the Indian subcontinent and contains various flora and fauna.
Uttarakhand has a total geographic area of 53,483 km2, of which 86% is mountainous and 65% is covered by forest. Most of the northern parts of the state are part of Greater Himalaya ranges, covered by the high Himalayan peaks and glaciers, while the lower foothills were densely forested till denuded by the British log merchants and later, after independence, by forest contractors. Recent efforts in reforestation, however, have been successful in restoring the situation to some extent. The unique Himalayan ecosystem plays host to many animals, plants and rare herbs. Two of India's great rivers, the Ganges and the Yamuna take birth in the glaciers of Uttarakhand, and are fed by myriad lakes, glacial melts and streams.
The Garhwal Himalayas are mountain ranges located in the Indian state of Uttarakhand.
The ecology of the Himalayas varies with climate, rainfall, altitude, and soils. The climate ranges from tropical at the base of the mountains to permanent ice and snow at the highest elevations. The amount of yearly rainfall increases from west to east along the southern front of the range. This diversity of climate, altitude, rainfall and soil conditions supports a variety of distinct plant and animal species, such as the Nepal gray langur
