Pai is a small town in northern Thailand's Mae Hong Son Province, near the Myanmar border, about 146 km northwest of Chiang Mai on the northern route to Mae Hong Son. It lies on the Pai River.
It's known for its nearby gorges, hot springs like the Tha Pai Hot Spring and waterfalls like Mo Paeng Waterfall. Downtown, food stalls and handicraft shops line Pai Walking Street.
Arguably one of the best places in Northern Thailand, the hippy enclave of Pai has been drawing backpackers and alternative types for years.
