Bhutan is a landlocked country. It is about 47,000 kilometres - roughly the size of Switzerland. It is located between Tibet in the north, Indian states of West Bengal and Assam in the south, and Arunachal Pradesh in the east.
Bhutan has three major land regions. The Great Himalayan region in the north rises more than 4300 m (14,000 ft) along the Tibetan border. This area is uninhabited except for a few scattered settlements in the high valleys. The Great Himalayas radiate southward into central Bhutan, creating the Middle Himalayan zone.
