Taman Nasional Bukit Tiga Puluh

Taman Nasional Bukit Tiga Puluh is a lowland tropical rainforest national park straddling Riau and Jambi provinces in central Sumatra, Indonesia, with its Riau section in Batang Gangsal, Indragiri Hulu. Established in 1995 and expanded in 2002, it covers about 144,223 hectares. It is notable as one of the last large lowland forests in Sumatra and a critical habitat for endangered Sumatran tiger, Sumatran orangutan, Asian elephant, and indigenous Talang Mamak and Orang Rimba communities.

Visitors can expect dense lowland tropical rainforest with hilly terrain, rivers and diverse flora and fauna. Exploration is primarily through guided jungle trekking on forest trails and river routes. Wildlife sightings may include primates, birds and, rarely, larger mammals. Visitors can also encounter traditional settlements of the Talang Mamak and Orang Rimba communities and learn about forest conservation. Facilities are basic and access requires a permit and local guide.
