Mahakam Ulu

Mahakam Ulu is an administrative regency located in the upper valley of the Mahakam River in East Kalimantan, featuring diverse geographical landscapes and distinct ecological zones. The territory comprises five districts spread across this expansive area.

The Indonesian government established this regency as an independent administrative unit in 2012, separating it from its previous jurisdiction. This division created a distinct territorial entity with its own governance structure.

Several local communities maintain distinct ways of living and practicing traditions throughout the territory. Visitors can observe how these groups carry forward their customs in everyday life and local gatherings.

Ujoh Bilang serves as the administrative center where basic services are coordinated for the territory. Access to services and facilities may vary depending on which district or area you are visiting within the region.

This territory shares a direct border with the Malaysian state of Sarawak and is the only regency in East Kalimantan with this cross-border connection. This geographical location shapes daily life and local economic ties for communities in the area.
