Bhutan is a sovereign country at the crossroads of East Asia and South Asia, located towards the eastern extreme of the Himalayas mountain range. It is fairly evenly sandwiched between the sovereign territory of two nations: first, the People's Republic of China (PRC) on the north and northwest. There are approximately 477 kilometres (296 mi) of border with the country's Tibet Autonomous Region (TAR), or simply Tibet. The second nation is the Republic of India on the south, southwest, and east; there are approximately 659 kilometres (409 mi) with the states of Arunachal Pradesh, Assam, West Bengal, and Sikkim, in clockwise order from the kingdom. Bhutan's total borders amount to approximately 1,139 kilometres (708 mi). The Indian state of Sikkim to the west, the India to the south, and the Assam state of India to the southeast are other close neighbours; the former two are separated by only very small stretches of Indian territory.

The mountains of Bhutan are some of the most prominent natural geographic features of the kingdom. Located on the southern end of the Eastern Himalaya, Bhutan has one of the most rugged mountain terrains in the world, whose elevations range from 160 metres (520 ft) to more than 7,000 metres (23,000 ft) above sea level, in some cases within distances of less than 100 kilometres (62 mi) of each other. Bhutan's highest peak, at 7,570 metres (24,840 ft) above sea level, is north-central Gangkhar Puensum, close to the border with Tibet; the third highest peak, Jomolhari, overlooking the Chumbi Valley in the west, is 7,314 metres (23,996 ft) above sea level; nineteen other peaks exceed 7,000 metres (23,000 ft). Weather is extreme in the mountains: the high peaks have perpetual snow, and the lesser mountains and hewn gorges have high winds all year round, making them barren brown wind tunnels in summer, and frozen wastelands in winter. The blizzards generated in the north each winter often drift southward into the central highlands.
Mountains and valleys dominate the topography of Bhutan.
