Mae Ngao National Park

Mae Ngao National Park is a protected forest area in Sop Moei and Mae Sariang districts of Mae Hong Son Province, northwestern Thailand, along the Mae Ngao River near the Myanmar border. Established in 1995, it covers approximately 257 square kilometers of mountainous mixed deciduous and evergreen forest. The park is notable for its river scenery, waterfalls, viewpoints, diverse wildlife and remote, undeveloped natural landscape popular for nature-based tourism.

Visitors can expect a remote mountainous park centered on the Mae Ngao River valley with dense mixed deciduous and evergreen forest, limestone hills and river scenery. Facilities are basic and focused on nature tourism, with a visitor centre, campsite and park bungalows near the headquarters. Areas to explore include forest trails, riverside viewpoints, Mae Ngao Waterfall and camping areas. Activities are low-impact such as trekking, birdwatching, photography and camping in a quiet, undeveloped natural environment.

Declared as Thailand's 56th national park on 27 June 1995 (B.E. 2538), established to protect the Mae Ngao River watershed and mountain forests covering about 257 sq km in Sop Moei and Mae Sariang districts along the Thai-Myanmar border.

The park lies in an area inhabited by Karen (Pakakayor) communities; surrounding riverside villages and traditional land-use patterns reflect the cultural landscape of the upper Salween basin encountered by visitors traveling to the park.
