Tiwai Island

Tiwai Island, a small forested island in the Moa River in Sierra Leone's interior, is one of the most important and rewarding wildlife destinations in West Africa, a community-run sanctuary protecting a precious remnant of rainforest. Despite its modest size, it boasts an extraordinary density and diversity of primates, with up to eleven species, including chimpanzees, the rare Diana monkey and colobus monkeys, alongside the elusive and endangered pygmy hippopotamus, over 130 bird species, and rich forest life. Explored on guided walks through the jungle and by canoe around the island, staying at a simple eco-camp, it offers a genuine and intimate rainforest wildlife experience.

What you actually see

• The primates - the eleven species of monkeys and chimpanzees.
• The pygmy hippo - the rare, elusive forest hippo.
• The forest walks and canoe trips - the guided exploration.
• The birdlife - the rich variety of forest birds.

When to go

November to April, the dry season, for the best access and conditions, as the rainy season can make travel and river crossings difficult; wildlife, especially the primates, is most active in the early morning and late afternoon. The island is reached by road and a canoe crossing, and visited on guided walks staying at the eco-camp.

Honest expectations

Tiwai is remote, reached by a long journey and a canoe crossing, with only a simple community-run eco-camp and basic facilities, so it is a rustic adventure rather than a comfortable trip, and wildlife, especially the shy pygmy hippo and chimps, is heard and glimpsed more than seen. As one of West Africa's most biodiverse and rewarding rainforest sanctuaries, though, with its remarkable primates and community-led conservation, Tiwai Island is a genuine highlight for nature lovers.
