Taï National Park: One of West Africa's Last Great Primary Rainforests (UNESCO World Heritage)

The West African coast was once covered by a vast primary rainforest stretching from Sierra Leone and Liberia to Côte d'Ivoire and Ghana; most of it has now disappeared. Taï National Park (Parc national de Taï), in the south-west of Côte d'Ivoire (in West Africa, French-speaking, the world's largest cocoa producer), is one of the largest surviving blocks of that forest. It holds special significance for researchers, birdwatchers and wildlife photographers.

A forest protected since 1926

Taï lies near the Liberian border, between the Cavally and Sassandra rivers, about 100 kilometres from the coast. The forest has been a forest reserve since 1926; it became a national park in 1972, a UNESCO Biosphere Reserve in 1978, and was inscribed on the World Heritage List in 1982, under criteria including natural landscape and biodiversity.

As for its size, World Heritage sources give about 3,300 square kilometres, while some other sources and recent reports cite more than 5,000 square kilometres; the difference may come down to whether adjoining protected areas are included. The terrain is gently undulating, with the highest point, Mont Niénokoué, at 396 metres. Annual rainfall is about 1,700 mm in the north and about 2,200 mm in the south-west.

Pygmy hippos and tool-using chimpanzees

Some 1,300 species of higher plants have been recorded at Taï, more than half of them found only in the Upper Guinean forest belt. Its fauna includes about 140 mammal species, 11 of them primates, and more than 250 bird species.

Flagship species	Why it matters
Western chimpanzee	Uses stones as tools to crack wild nuts and hunts colobus monkeys collectively; long studied by primatologists
Pygmy hippopotamus	A small hippo endemic to West African forests, and rare
Diana monkey, colobus monkeys	Representative of the park's many monkey species
Bongo, pangolins, leopard	Several threatened forest mammals
Shelley's eagle-owl	One of Africa's largest owls, very rarely photographed

Taï's chimpanzees have been observed by a Swiss research team since 1979 and have been studied by primatologists for decades. In the 1980s the park was estimated to hold more than 2,000 of them, but numbers may have fallen since.

The main conservation pressures are poaching, illegal gold mining, and the growing isolation of the forest as surrounding land is developed. Conservation sources note that primate numbers have at times fallen sharply between surveys.

Ecotourism: niche, and requires planning

Taï currently receives few visitors. The drive from Abidjan takes about 10 hours, and road conditions are not always good. The village of Djouroutou in the south has an eco-lodge that serves as a base for entering the forest; chimpanzee-tracking outings usually set off before dawn and involve walking through the forest.

Reports in 2026 indicate that Côte d'Ivoire's Office of National Parks and Reserves (OIPR) and its conservation partners are planning small-scale, low-impact ecotourism — boardwalks and clearly marked trails, for example — rather than large resorts. For itineraries and permits, contact the OIPR or one of its partner local guiding organisations directly.

One line for Asian readers

Taï is not an ordinary tourist attraction but a research rainforest that demands patience and advance planning. If you care about biodiversity or corporate nature-conservation partnerships, it is the best gateway to understanding the value of West Africa's forests.
