Uttaradit

Covering 7,906 km² and home to 436,283 residents in 2024, Uttaradit lies 488 km north of Bangkok and borders Phrae, Nan, and Laos' Xaignabouli Province to the east. The Nan River defines much of the province's geography, and forests cover 55.9% of its area across three national parks and multiple wildlife sanctuaries. The Queen Sirikit Dam, approximately 45 km north of the provincial capital, impounds a reservoir of roughly 250 km² shared with neighbouring Nan Province and is a popular destination for boat trips and bungalow stays. Ton Sak Yai Park preserves the giant teak tree, measuring 9.87 metres in circumference and 37 metres in height. Uttaradit is also celebrated for its langsat and odourless durian varieties, which draw Thai visitors during the annual fruit festival each September.
