Tai National Park is the largest remaining tract of primary tropical rainforest in West Africa and a UNESCO World Heritage Site. Covering over 3,300 square kilometres in the southwest corner of Ivory Coast, the park protects an ecosystem that has largely disappeared elsewhere in the region. If you want to see what the Upper Guinea forest looked like before logging and farming took most of it, this is the place.
The park is best known for its chimpanzee population, which has been studied by researchers since the 1970s. The Tai Chimpanzee Project has documented tool use and complex social behaviour here that has contributed significantly to primatology. Visitors can arrange guided treks to observe habituated chimpanzee groups, though sightings are never guaranteed in dense forest. Other wildlife includes pygmy hippos, forest elephants, Diana monkeys, and a remarkable diversity of birds and butterflies.
Getting to Tai requires some effort. The nearest town is Tai, reachable by road from San Pedro or Man, though road conditions vary with the season. The rainy season from May to October makes some access routes impassable, so the dry months from November to March are the best time to visit. Facilities are basic — expect simple guesthouses in Tai town and ranger-run campsites near the park. You will need to arrange a guide through the park office, as independent entry is not permitted.
