Bui National Park, National park in the Bono and Savannah regions, Ghana

Bui National Park is a protected area in the Bono region of northern Ghana, covering woodland savanna and forested stretches along the Black Volta River. A large reservoir formed by the Bui Dam sits within the park, adding open water to a landscape that otherwise alternates between dry grassland and riverine forest.

Bui National Park was established in 1971. The Bui Dam was constructed from 2007 to 2013, and its reservoir inundated part of the park. The hippos moved to the shallower northern stretch of the Black Volta, and the park lost some of its value for tourism.

The Bui Dam was built between 2007 and 2013, and its reservoir flooded a large part of the park. Hippos moved to the shallower northern stretch of the Black Volta after the flooding. The dam reduced the park's value for tourism, and plans to develop it for visitors were not realised.

The park is in a remote part of northern Ghana and is most easily reached by private vehicle or hired car from the nearest larger town. Visiting during the dry season, roughly December through February, gives the best chance of seeing animals, as they tend to gather near the water at that time.

Bui National Park is one of the few places in Ghana where wild hippos can still be seen, often resting in the shallows of the reservoir during the cooler parts of the day. Black and white colobus monkeys also live here, and their loud calls frequently signal their presence in the trees before you spot them.
