Thimphu is the capital of Bhutan and is therefore the most populated district in the country, with about 60,000 people. You can easily spend several days in Thimphu visiting all the sights. There are many attractions in and around Thimphu Valley, including museums, monasteries, temples, dzongs, a zoo, archery fields, restaurants, handicraft shops, the weekend market, the National Library, the School of Arts and Crafts, a traditional paper factory, a radio tower (which affords a gorgeous view of the valley), and the National Institute of Traditional Medicine.
