Ureca is the end of the road on Bioko. The island's southernmost and most isolated village looks out from a soaking hillside over a coast of black volcanic sand where waterfalls drop straight into the sea and where, between November and February, leatherback turtles, the largest marine reptile on the planet, come ashore to nest. There are no hotels or restaurants: there is rainforest, beach, falling water and very few people.
It is also, quite literally, the rainiest place in Africa: around 10.450 millimetres a year, a figure that puts it among the wettest spots in the world. That extraordinary rainfall is what sustains the Gran Caldera de Luba rainforest, which begins right behind the village, and what for centuries kept this corner of Bioko safe from roads, plantations and visitors. Until recently it could only be reached on foot or by boat.
Today a modern road runs down from Luba and ends at a car park beside the forest, which has made Ureca the most accessible nature destination in the south of the island. This guide explains how the visit is organised, when to go to see turtles, what to expect from the weather and the checkpoints along the way, and why it pays to arrive with everything you need and no rush.
Ureca is a Bubi village at the southern tip of Bioko that for centuries lived cut off from the rest of the island by its geography: rugged terrain, torrential rivers and the heaviest rainfall in Africa. While the north of Fernando Poo filled up with cocoa estates under Spanish administration, the south stayed on the margins of the colony, with the Christian name San Antonio de Ureca added to the local place name and little else. That isolation preserved its surroundings: the Gran Caldera de Luba rainforest, declared a Scientific Reserve, and black sand beaches that turned out to be among the most important sea turtle nesting sites in the Gulf of Guinea. Only in recent decades did a road connect it with Luba, opening the village to fledgling tourism and, at the same time, to new pressures on its wildlife.

Origins, formation and what the sources say.
Ureca's story starts with its climate, because the climate explains almost everything else. The village receives around 10,450 millimetres of rain a year, the highest figure recorded on the African continent and one of the highest on the planet. To put it on an Argentine scale: that is more than ten times what falls on Buenos Aires in a year, and quite a bit more than in the wettest parts of Misiones.
The cause is a very specific geographical combination. Bioko is the emerged summit of a volcanic chain, the Cameroon line, that runs out into the Gulf of Guinea. The humid winds of the Atlantic monsoon arrive loaded with moisture from the ocean and hit the southern wall of the island's southern massif head-on, a massif that rises to 2,261 metres at the peak of the Gran Caldera. The air is forced to rise, cools and lets it all go. Ureca sits right on that wall, at about 186 metres above sea level, in the front row.
The result is a climate with no real dry season: between November and March it rains less, but it still rains, almost every day. That constant water feeds a rainforest of extraordinary density, short torrential streams that tumble in waterfalls straight onto the beach, and an isolation that for centuries made this corner of the island almost impossible to reach.
Bioko was settled by the Bubi, a Bantu people who came by sea from the mainland centuries ago and developed a culture of their own on the island, with kings, mountain villages, a distinctive social organisation and an economy based on farming, hunting and gathering. The Bubi spread across the whole island and adapted to very different environments. The south, this soaked slope cut by ravines, was always the hardest and the most remote.
When the Europeans arrived, the south was left out. The Portuguese navigator Fernão do Pó sighted the island in 1472. Portugal ceded it to Spain in 1778 under the Treaty of El Pardo. The British founded Port Clarence on the north coast in 1827 to fight the slave trade. Spain took effective possession in 1843 and renamed the town Santa Isabel. All of that happened more than a hundred kilometres from Ureca, at the other end of the island, and it changed very little down here.
The current place name, San Antonio de Ureca, reflects that double history: the Bubi name of the place plus the patron saint added by Spanish Catholic evangelisation, which was very active on the island from the mid-19th century through the Claretian missionaries. But the village went on living from fishing, subsistence farming and the forest, with minimal contact with the colonial administration.
While the north of Fernando Poo filled up with cocoa plantations, the crop that made the colony prosperous from the late 19th to the mid-20th century with thousands of labourers brought from Nigeria, the south was left as it was. There were no roads to get the harvest out, no ports, and the rain made drying the beans impossible. That economic marginality is, paradoxically, the reason Ureca still has natural surroundings that barely exist anywhere else in West Africa.
Below Ureca stretches a coast of black volcanic sand that turned out to be far more important than anyone suspected. Four species of sea turtle come ashore to nest on these beaches between November and March: the leatherback, the green, the hawksbill and the olive ridley. The star is the leatherback, Dermochelys coriacea, the largest marine reptile in the world. Females weighing hundreds of kilos emerge at night, drag their shells across the sand, dig the nest with their back flippers, lay more than a hundred eggs and return to the sea before dawn.
The beaches of Moaba, Moraka and their neighbours towards Punta de Santiago hold a large share of that nesting, which puts southern Bioko among the most important nesting sites in the Gulf of Guinea. For centuries this cycle repeated itself with no scientific witnesses. For the local communities, the turtles and their eggs were above all food.
The change came in the 1990s. Between 1995 and 1998 the Spanish NGO Amigos de Doñana ran a conservation programme in southern Bioko focused on sea turtles, species protection, environmental education and the promotion of ecotourism. Soon after, in 1998, the Bioko Biodiversity Protection Program was launched, an academic partnership between the Universidad Nacional de Guinea Ecuatorial, Drexel University in Philadelphia and INDEFOR-AP. It set up permanent camps at Playa Moraka and Playa Moaba and has kept up nest monitoring season after season ever since, along with primate censuses in the forest above.
That work changed the status of Ureca's beaches. They went from being a local food source to an internationally recognised conservation asset and, more and more, the main reason anyone from outside makes the long trip to the south of the island.
For almost all of its history, Ureca could only be reached on foot or by boat. Accounts from people who travelled down to southern Bioko in the 20th century describe days of walking along muddy trails, crossing swollen rivers and making difficult landings on an exposed coast. That isolation shaped village life: nothing came in or went out easily, and the state administration showed up only now and then.
That has changed in recent decades. A modern road was built from the Luba area on the west coast down to the south of the island. It ends at a large car park next to the forest, a short distance from the village and the beach. The trip from Malabo, once an expedition, became a half-day journey. A police checkpoint was set up at the Luba turn-off, where the documents of people heading south are checked. Checkpoints are common all over the country.
The effect has cut both ways, and that is the open debate in southern Bioko. For the families of Ureca, the road meant the end of isolation: access to markets and health services, and the chance to receive visitors and work as guides and porters. For the wildlife, it meant risk. The same road that brings tourists and researchers also shortens the trip for hunters into an area that used to be protected simply by being so hard to reach. Censuses by the Bioko Biodiversity Protection Program show primate populations that have fallen since the first counts in 1991 and have not recovered their original levels. Hunting for bushmeat is the main threat, and better access makes it worse.
Until 2018, travel within the country could also require prior authorisation from the ministry in charge of tourism. That requirement has since been relaxed, but it is worth keeping in mind because the rules change without warning.
Equatorial Guinea is one of the least visited countries in the world. Several things keep visitor numbers tiny: a visa requirement for almost all travellers, high prices inherited from the oil economy, scarce tourist infrastructure and strong state control, with restrictions on photography and frequent roadside checks. In that context, Ureca is one of the very few places in the country with a recognisable tourism product: the turtle night.
Today there are commercial tours that leave from Malabo, cross the island, drive down to the south and offer a night-time watch on the beach. The best-known one includes an overnight stay and sells for around 440 dollars per person. These are small operations with small groups, local guides and no fixed infrastructure at the destination. There are no hotels, restaurants or shops in the village, and everything (water, food, tents, torches) is brought from Malabo or Luba.
Then there are the serious expeditions into the Reserva Científica de la Gran Caldera de Luba, which starts just behind the village. These are treks of a week or more, with porters hired in Ureca, to the Moaba and Moraka camps. Groups are limited to four people, and they only run between November and March. In practice, that local hiring is the strongest economic argument for conservation: it makes the forest and the turtles worth more alive.
The legal framework has shifted too. Law 4/2000 created the country's National System of Protected Areas. It was repealed in 2003, which left more than two decades without proper regulation. In 2025, Law 6/2025 was enacted, a new Protected Areas Law that reorganises the system, aims for the international target of protecting at least 30 % of the territory by 2030 and explicitly includes ecotourism among its tools. If that bet pays off, Ureca, the rainiest, southernmost and most isolated village on Bioko, has everything it takes to become its best example.
