Gola Rainforest National Park is a world heritage listed national park in Sierra Leone.

The park is in three parts; North Gola, Central Gola and South Gola. Across the border in Liberia there is also a Gola National Park. The park, 71,070 ha in size protects the largest areas of rainforest in Sierra Leone, which are part of the Upper Guinean forests. Together with nearby Tiwai Island it was listed as a natural world heritage site in 2025.

The Gola Conservation Centre at Lalehun is the quickest entry point into the park from Freetown or Bo. It is 40 km (approx. 1.5 hours) from Kenema in Gola Central.

Visitors are required to make a booking prior to their trip to arrange for permits, food, accommodation, camping equipment and guides. All visitors entering the park and on all camping trips must be accompanied by a member of staff and community guide.

From the Gola Conservation Centre there is a network of trails that lead into the forest offering opportunities for trekking and camping in the heart of the National Park. Visitors are also able to visit an ancient grave site of the original Gola people.

From Diana Monkey Lodge there are two half-day nature trails that provide an opportunity to spot resident groups of Diana Monkeys and possibly other primates such as the Red Colobus and Black and White Colobus. A 2-day/1-night camping trip along the Mahoi River involves easy to moderate walking only. A more rugged 3-day trek through Gola South to the Tiwai Island Wildlife Sanctuary is also possible. The nearby Nemahungoima Village offers visitors an opportunity to experience Mende village life.

Belebu Community is 40 km from Kenema (1.5-2 hours), just south of Lalehun in Gola Central. The landscape is known for its mountain climbs and panoramic views, which offer great opportunities for trekking. Belebu village guides will help you to spot wildlife, including a Picathartes nesting site and various monkey species.
