If there is any country on Earth that qualifies as Eden - not just in part, but in it's entirety - I believe it is Bhutan.
Bhutan, the last Buddhist kingdom on the Himalayas’ eastern edge is known for its monasteries, treks and dramatic landscapes that range from subtropical plains to steep mountains and valleys. In the High Himalayas, peaks such as 7,326 m Jomolhari are popular trekking destinations. Paro Taktsang monastery (also known as Tiger’s Nest) clings to cliffs above the forested Paro Valley. Bhutan is maintaining their environment and cultural identity even after all the globalization.
