Huai Nam Dang National Park essentials

Address: Huai Nam Dang National Park, northern Thailand (Chiang Mai/Chiang Dao area)

Huai Nam Dang National Park is a protected mountainous area in northern Thailand located near the town of Pai, known for panoramic highland scenery. The park conserves montane forest and supports recreational activities.

Created to protect the region’s forested highlands, the park preserves typical northern Thai montane ecosystems and serves both conservation and visitor-recreation roles. It functions as a regional destination for local tourism and nature study.

Straddling parts of northern Thailand’s highlands near Pai, the park lies within the broader border area of Chiang Mai and Mae Hong Son provinces and is accessed from roads serving those towns.

  • Best time to visit: Clear, cool weather between November and February provides the best visibility for the park’s mountain viewpoints and sea-of-mist scenes.

Exploring Huai Nam Dang National Park#

The park covers a mountainous area of 1,247 square kilometres in the west of Chiang Mai Province, roughly between Chiang Dao and Pai. The main entrance is on Highway 1095, about 110 kilometres from Chiang Mai on the way to Pai.

Sea of mist. The park is well known among Thais, who flock here between November and February to watch the sunrise from a viewpoint near the entrance. The view stretches across the Mae Taeng valley to the jagged peaks of Chiang Dao, an impressive sight when the valley fills with mist. A couple of nature trails begin at the viewpoint, and several hill-tribe villages are scattered through the park.

Hot springs. The Tha Pai Hot Springs are easily reached from the town of Pai, but the finest springs in the park are at Pong Duat, where you can soak in pools of varying temperature on a hillside. Pong Duat is signposted off Highway 1095 east of the entrance, from where it is a roller-coaster 10-kilometre drive to the springs.
