Main image

Namtok Mae Surin National Park is a protected area in northwestern Thailand’s highlands, named for the prominent Mae Surin waterfall within its boundaries. The park preserves montane forest, streams, and waterfall landscapes and is used for day hikes and nature recreation.

Trails in the park lead to the waterfall and through forested slopes characteristic of the region, and the area supports a mix of evergreen and deciduous forest communities. The park is also linked with local ethnic communities and hill-country agriculture outside the protected area.

The site was designated for conservation to protect its watershed, waterfall features, and upland forest habitats while providing access for visitors on marked routes.

The park sits in the highland districts of northwestern Thailand and is reached by road from nearby towns in the province; its terrain is hilly and forested with permanent streams feeding the waterfall.

  • Mae Surin Waterfall: The park is named for the Mae Surin waterfall, a primary attraction that draws day visitors and local picnickers.

  • Bring insect repellent and a light rain jacket: the park sits on a watershed and clouds can roll in fast.
