The realm of Bhutan is a Southeast Asian nation nestled at the east of the Himalayas and surrounded by India, Tibet, Nepal and Bangladesh. Thimphu, the capital, lies in a gorgeous, wooded valley, rambling up a hillside on the bank of the Thimphu Chhu (river). It is the lone world capital without traffic lights. Some of the highlights of the country include Bumthang Dzongkhag, an antique showcase of traditional Tibetan-style life and culture, and the treasure that makes Bhutan the last fortress of the grand kingdom of the Himalayas. There is also the Phobjika Valley, a treasure trove of thrilling nature treks and textile makers.
