Umphang Wildlife Sanctuary

Umphang Wildlife Sanctuary is a protected area consisting of mountainous and forested terrain with considerable variation in elevation. The region features multiple river systems, dense woodlands, and steep valley sides that define its landscape.

The area gained official protected status in 1989 as part of Thailand's Western Forest Complex. This designation came from recognition that the region played an important role in the borderland ecosystem.

Local Karen communities have given names to natural features in this region that reflect their connection to the land. These names, like Thi Lo Su for the major waterfall, show how communities have shaped their relationship with the area through language and tradition.

The area is accessible via Highway 1090 from Mae Sot and offers varying conditions depending on the season. The drier months from November to February provide better access to trails and water features.

The sanctuary contains Thi Lo Su, a major waterfall with multiple cascades occurring on different levels. This multi-tiered waterfall formation results from the region's topography and natural water flow patterns.
