Chiang Mai is the cultural capital of northern Thailand, a city of over 300 Buddhist temples enclosed within a square moat and ancient city walls. The old city's Wat Phra Singh and Wat Chedi Luang are outstanding examples of Lanna architecture, while the Sunday Walking Street and Night Bazaar are Thailand's finest markets for handicrafts and street food. The surrounding mountains offer elephant sanctuaries, jungle trekking, hill tribe villages, and the Doi Inthanon National Park — home to Thailand's highest peak.
