Cross River National Park is the great natural treasure of south-eastern Nigeria: one of the last great tropical rainforests in West Africa, an ocean of primary forest stretching across the mountains along the border with Cameroon. Created in 1991 from older forest reserves, it protects about 4.000 square kilometres in two sectors, Oban in the south and Okwangwo in the north, with biodiversity that makes it one of the most important ecological hotspots on the continent.
This is where one of the most endangered primates on the planet survives: the Cross River gorilla, the rarest gorilla subspecies in the world, with just a few hundred individuals spread between Nigeria and Cameroon. The forest is also home to chimpanzees, drills (a critically endangered relative of the mandrill), many species of monkey, forest elephants, hundreds of birds and lush plant life. Seeing a gorilla is almost impossible, but exploring its home is an unforgettable experience for the adventurous traveller.
This guide explains what visiting Cross River is like: Kanyang Tourist Village as a base near Calabar, trekking through the Oban forest, the link with conservation projects such as the Drill Ranch on Afi Mountain, and what you need to know before heading into a wild park with no frills, where the star is not comfort but untouched nature and the fight to save unique species.
Cross River National Park was created in 1991 by joining former forest reserves to protect Nigeria's largest tropical rainforest, home to the Cross River gorilla, which was rediscovered by science in this area in the late 20th century after fears it had gone extinct. The region, inhabited by peoples such as the Ejagham and Boki, was historically a frontier between British and German colonial spheres. Today the park is a symbol of conservation in West Africa, managed by the Nigeria National Park Service together with international NGOs working to save its gorillas, drills and chimpanzees. The full story is on our history page.

Origins, formation and what the sources say.
Cross River National Park protects a fragment of a very old ecosystem: the humid tropical rainforest of West Africa, which once formed a continuous belt from Sierra Leone to Cameroon and the Congo. These Guinean forests are among the oldest on the planet. They hold exceptional biodiversity, the result of millions of years of evolution in a warm, rainy climate that escaped the ice ages that swept other latitudes.
The Cross River area lies in south-eastern Nigeria, in the mountains and hills along the border with Cameroon. It is especially valuable because it forms part of the biodiversity 'hotspot' of the Guinean Forests of West Africa and of the transition zone with the Cameroon highlands. Lowland rainforest (in Oban) and montane forest (in Okwangwo and Afi) meet here, with some of the highest rainfall in Africa. That mix has allowed countless species of plants, insects, birds and mammals to survive, many of them rare or endemic.
For thousands of years, this forest was home to peoples such as the Ejagham (Ekoi), the Boki and others. They were hunters, gatherers and farmers who built a deep knowledge of the forest and a strong cultural bond with it, which shows in their traditions, their art and ideographic writing systems such as nsibidi. The forest was not 'virgin' in the sense of uninhabited. It was a territory that human communities lived in and managed for generations.
During the colonial carve-up of Africa in the late 19th century, the Cross River region ended up on the border between British rule (Nigeria) and German rule (Cameroon). The borders drawn by the European powers split lands and peoples, and placed these forests on the edge of two empires. After the First World War, German Cameroon was divided between France and Britain. Part of what was called 'British Cameroons' was run together with Nigeria, which shaped the history of the border area.
Under British colonial rule, much of this forest was declared forest reserve, mainly to regulate logging and protect water catchments. Reserves such as Oban were set up in the first decades of the 20th century. Reserve status was meant more for using the forest than for strict conservation. Even so, it helped large areas of forest survive fairly intact until the late 20th century, when deforestation sped up across the rest of West Africa.
Meanwhile, the area's flagship wildlife remained little known to Western science. The Cross River gorilla in particular had been described in the early 20th century, but was then almost forgotten. For decades, people feared it had died out in this remote corner between Nigeria and Cameroon.
The big turning point came in the late 20th century. In the 1980s and 1990s, researchers and conservationists confirmed that a small population of Cross River gorillas still survived in the mountains on the Nigeria–Cameroon border. This is the most northerly and westerly gorilla subspecies, and it had been all but given up for lost. The find put the region on the world conservation map: this was one of the most threatened great apes on the planet, with only a few hundred individuals left.
Pushed by international concern and with support from organisations such as the Wildlife Conservation Society (WCS) and the World Wide Fund for Nature, the Nigerian government created Cross River National Park in 1991. It joined the former Oban forest reserve in the south and the Okwangwo reserve in the north into a single large protected area of about 4,000 square kilometres. The goal was clear: save Nigeria's largest remaining rainforest, and with it the gorillas, chimpanzees, drills and other wildlife.
At almost the same time, on nearby Afi Mountain, the organisation Pandrillus set up the Drill Ranch. It rescues and breeds the drill, another critically threatened primate, and takes in chimpanzees orphaned by the illegal trade. These projects made the Cross River region one of the most important frontlines of primate conservation in all of West Africa.
Protecting Cross River has been a hard fight from the start. The threats are many: poaching, including the hunting of gorillas, chimpanzees and drills for the 'bushmeat' trade, plus illegal logging, farmland expansion, road building and pressure from a rural population that depends on forest resources. The Cross River gorilla's population is tiny and fragmented. It is still critically endangered, and every individual counts.
Conserving the park has relied heavily on cooperation between the Nigeria National Park Service, international NGOs and, above all, local communities. People have come to understand that you cannot protect the forest against the people who live in it, only with them. That is why the projects work on environmental education, alternative livelihoods, ecotourism and community involvement, and train local people as guides and rangers. Cross-border projects with Cameroon aim to protect the gorillas that move across the border.
The balance is fragile and resources are scarce. Over the years, proposals for roads cutting through the forest (the controversial Cross River 'superhighway') and for logging concessions have alarmed conservationists. To them, every step forward for the human frontier is a risk to one of the last great forests of West Africa. The park's history is largely one of a constant struggle to reconcile development with the survival of nature.
Today, Cross River National Park is much more than a nature destination. It is a symbol of what remains of Nigeria's great rainforest, in a country of more than two hundred million people that has lost most of its original forests. Gorillas, chimpanzees, drills and forest elephants still survive here, along with a fabulous range of birds, butterflies and plants. That is close to a miracle, and it makes this border corner a treasure of global importance.
For travellers, Cross River offers a completely different experience from the savannah safaris of eastern and southern Africa. There are no big herds to spot easily from a vehicle. Instead, there is dense, humid, noisy forest that you explore on foot with guides, following tracks and sounds rather than chasing guaranteed sightings. It is a destination for people who love wild nature, adventure and conservation, and who are happy to swap comfort for authenticity.
The park's future depends on Nigeria and the world continuing to back it: for its irreplaceable wildlife, for the communities who live there, and for the idea that the country's last great forest is worth saving. The story of Cross River runs from the rediscovery of a gorilla thought to be extinct to community ecotourism projects. It is a second chance for one of Africa's most valuable rainforests, and the rest of it is still to be written.
