The most prominent landmark of Dehradun is the Victorian clocktower in the main commercial district, which incidentally you can't tell from just another dusty marketplace. From here, the trunk line of Rajpur Road goes northwards right up to Rajpur, forking off towards Mussoorie after a point. About 4 kms up the Rajpur Road is the sprawling campus of the Survey of India, set up by the British in 1767. The centre of all major mapping and survey activities in India, its historical high point was measuring the height of Everest, which was then named after the Surveyor-General, Sir George Everest.
Across the dry river bed of the Bindal Rao on Kaulagarh road are the Doon School ( the Eton of India) and the huge red brick campus of the Forest Research Institute. Forest Research Institute, Dehradun
Built in 1914, the FRI campus is a verdant expanse of Botanical Gardens and forests. Within, is a library stocked with a huge collection of books on forestry, a bookshop and a museum divided into six parts. The museum is worth visiting, with its array of wood samples, insects and wildlife. The Wadia Institute of Himalayan Geology also has an interesting museum displaying rock samples, semi-precious stones and Himalayan fossils.
6 kms from the centre of town is the cave shrine of Tapkeshwar, dedicated to Lord Shiva. Lying next to a swift flowing forest stream, the cave has a stone lingam with milky water dripping onto it from the ceiling. Every year, during Shivratri the entire area is taken up with festivities because of a fair where devotees jostle with holy men to gain access to the cave. Outside, stalls selling knick-knacks, food items and toys drum up a festive atmosphere. You can also get a shot at having a special bhang (cannabis) drink.
About 8 kms from Dehradun is Robber’s Cave, also known as Guchhu Pani. A popular picnic spot, the cave is reached after a kilometre trek up the hills. Here, waters of a spring vanish underground and reappear some distance away.
At Rajpur, 12 kms from the centre of town is a Tibetan settlement with a new gompa called the Shakya Centre. Decorated with ornate frescoes, the settlement has a centre for Tibetan medicine.
