Semuliki National Park, situated in the remote Bundibugyo District of western Uganda, is a hidden gem on the eastern edge of the vast Ituri rainforest—one of Africa’s oldest and most biodiverse ecosystems. The park borders the Democratic Republic of Congo (DRC) and gets its name from the winding Semuliki River, which elegantly marks the boundary between the two countries.

As East Africa’s only true lowland tropical rainforest, Semuliki stands apart from other Ugandan parks, offering a unique blend of Central African flora and fauna, geothermal wonders, and deep ecological richness.

Biodiversity Hotspot

Semuliki’s rainforest is a continuation of the Congo Basin’s Ituri Forest, and is one of the richest and most diverse tropical rainforests in Africa. The park is home to:

• 336 tree species, with 24 found nowhere else in East Africa

• A number of these species are classified as rare or endangered, underscoring Semuliki’s ecological importance

This thick jungle is also known for its lush swamps, meandering oxbow streams, and incredible natural beauty that seems to go on endlessly to the horizon.
