Sikkim is sheer magic. With its unique culture and natural landscape, Sikkim is a picture of perfection and pristine purity. Perhaps, there is no part of the world, which offers a spectacular scene with every turn of the road as Sikkim. Bounded by foreign nations on three sides, it shares its boundary with the sister state of West Bengal. Surrounded on three sides by precipitous mountain walls, Sikkim appears as a small rectangular Gem. Sikkim is like a stupendous stairway leading from the western border of the Tibetan plateau down to the plains of West Bengal, with a fall of about 5,215 metres in 240 kms.
Sikkim, in the west is bound by the north-south spur of the Great Himalayan Range which includes the world's third highest peak, Khangchendzonga and down to its south is Singalila ridge. In the north it is bound by Dongkia range and also partly includes the Tibetan Plateau. In the east it is bound by the Chola range. The average steepness is about 45 degree. Sikkim is the main catchment area for the beautiful river Teesta, which has its main source from Chho Lhamo lake in the north and is further strengthened by many streams and rivers of which Tholung, Lachung, Great Rangeet and Rangpo are important drainers. It also has about 180 perennial lakes, among which Khachoedpalri, Gurudongmar, Chho Lhamo and Men Moi Tso are some of the most scenic.
Gangtok is a municipality, the capital and the largest town of the Indian state of Sikkim. It also is the headquarter of the East Sikkim district. Gangtok is located in the eastern Himalayan range, at an elevation of 1,650 m (5,410 ft). The town's population of 100,286 (2011 Census) belongs to different ethnicities such as Nepalis, Lepchas and Bhutia. Nestled within higher peaks of the Himalaya and enjoying a year-round mild temperate climate, Gangtok is at the centre of Sikkim's tourism industry.
The precise meaning of the name "Gangtok" is unclear, though the most popular meaning is "hill top". Today, Gangtok is a centre of Tibetan Buddhist culture and learning, with the presence of several monasteries, religious educational institutions, and centre for Tibetology.
