Bhutan lies in the eastern Himalayas, between Tibet to the north, the Indian territories of Assam and West Bengal, to the south and east, and Sikkim to the west . Bhutan is a tiny country has a total area of about 47,00 square KM. Bhutan is loacted in the heart of the high Himalayan mountain range, Bhutan is a land-locked country like Nepal surrounded by mountains.The sparsely populated Greater Himalayas, bounded to the north by the Tibetan plateau, reach heights of over 7,300 meters (23,950ft.), and extend southward losing height, to form the fertile valleys of the Lesser Himalayas divided by the Wang, Sunkosh, Trongsa and Manas Rivers. Monsoon influences promote dense forestation in this region and alpine growth at higher altitudes. The cultivated central uplands and Himalayan foothills support the majority of the population. In the south, the Duars (the gates or doors; the traditional 18 points of access into Bhutan from the Indian plain.) drop sharply away from the Himalayas into the large tracts of semi-tropical forest, savannah grassland and bamboo jungles. Bhutan has remained a hidden Kingdom by choice for many years. Today, it has opened its door to visitors, and a small number of people are welcome to explore the Kingdom.
