Mussoorie is a popular hill station, situated in the foothills of the Himalaya ranges, is also known as the Queen of the Hills. The adjoining town of Landour, which includes a military cantonment, is considered part of 'greater Mussoorie', as are the townships of Barlowganj and Jharipani. Being at an average altitude of 2,000 meters (6,600 ft.), Mussoorie, with its green hills and varied flora and fauna, is a fascinating hill resort. Commanding snow ranges to the north-east, and glittering views of the Doon Valley and Shiwalik ranges in the south, the town is said to present a 'fairyland' atmosphere to tourists.

The history of Mussoorie dates back to 1825 when Captain Young, an adventurous British military officer, together with a Mr. Shore, the resident Superintendent of Revenues at Dehradun explored the present site and jointly constructed a shooting lodge. This laid the foundation of this holiday resort which now has few rivals.Its name is derived from a shrub locally called mansoor behind the house of the Captain. Some believe that perhaps that is reason behind the name of the town, which is also known as mansoori among the natives of the surrounding area. The main promenade in Mussoorie is called, as in other hill stations, the Mall. In Mussoorie, the Mall stretches from Picture Palace at its eastern end to the Public Library (shortened to 'Library') at its western end. During the British Raj, signs on the Mall expressly stated: "Indians and Dogs Not Allowed"; racist signs of this type were commonplace in hill stations, which were founded 'by and for' the British. Motilal Nehru, the father of Jawahar Lal Nehru, deliberately broke this rule every day whenever he was in Mussoorie, and would pay the fine. The Nehru family, including Nehrus's daughter Indira were frequent visitors to Mussoorie in the 1920s, 1930s and 1940s. They also spent much time in nearby Dehradun, where Nehru's sister Vijayalakshmi Pandit ultimately settled full-time.

In April 1959, after fleeing Chinese occupation of Tibet, the Dalai Lama established the Tibetan Government of Exile in Mussoorie. The Government of Tibet in exile eventually moved to Dharamsala in Himachal Pradesh. The first Tibetan school was established in Mussoorie in 1960. Tibetans settled mainly in Happy Valley in Mussoorie. Today, some 5,000 Tibetans live in Mussoorie.
