Bhutan, also known as the last Shangri La and the Land of Thunder Dragon is perhaps the most unknown but fascinating travel destination left. The climate of Bhutan is variable from region to region. While it is tropical in the southern plains, in the central valleys one experiences cool winters and hot summers. On the other hand, in the Himalayas severe winters and cool summers are prevalent. This makes a Bhutan tour much more pleasant. There are also many trekking zones in Bhutan , some of then perhaps the best in the world. There are many trails in Bhutan yet to be discovered. And all this is possible now as the government has become much more focused on the tourism promotion of Bhutan .
