Sikkim is a landlocked Indian state nestled in the Himalayas. It is the least populated state in India, and the second smallest in area after Goa. Sikkim was an independent state ruled by the Chogyal monarchy until 1975, when a referendum to make it India's twenty-second state succeeded. The thumb-shaped state borders Nepal in the west, The People's Republic of China to the north and east, and Bhutan in the south-east. The Indian state of West Bengal borders Sikkim to its south. The official language is Nepali, and the predominant religions are Hinduism and Vajrayana Buddhism. Gangtok is the capital and largest town.

Despite its small size, Sikkim is geographically diverse, owing to its location at the Himalayan foothills. Terrain ranges from tropical in the south to tundra in the north. Kanchenjunga, the world's third highest peak, is located in Sikkim, straddling its northern border with Nepal. Sikkim has become one of India's most visited states owing to its reputation for untouched scenic beauty and political stability.
