Landlocked between China in the north and India in the south, east and west, Bhutan is a small country with an area of 46,500 square kilometers.

Bhutan is divided into three zones. The southern zone is characteristic of low foothills and dense tropical forests. With an average temperature of 20 degrees centigrade, this region is hot and humid. The central zone is situated between 2000 and 3500 meters.

The central zone is divided into three regions: Western Bhutan, Central Bhutan, and Eastern Bhutan. The northern zone stretches from west to east between 6800 meters to 7400 meters, forming part of the Great Himalayas.
