São Tomé and Príncipe Ecotourism: The Atlantic Island Nation That Has Quietly Become Africa’s Benchmark

25

São Tomé and Príncipe covers 142 square kilometres, and the whole nation counted 40,822 visitors in 2024. Yet on 27 September 2025, UNESCO made São Tomé and Príncipe the first country on earth to have its entire territory, land and sea, recognised as a World Biosphere Reserve.

The claim is easy to make and hard to prove. What follows tests it against four pieces of evidence: the legal architecture of the reserves, the arrival and spending data, the people and species doing the conservation work, and the October 2025 crisis that exposed who holds power on Príncipe. Each one points to the same conclusion about where the model is strong and where it is exposed.

The order of events explains the model. Príncipe joined UNESCO’s biosphere network on 11 July 2012, when the Man and the Biosphere Programme council met in Paris. The reserve covers 71,592.5 hectares and includes the whole island, its islets, and the surrounding sea. Príncipe is the oldest of three oceanic volcanic islands in the Gulf of Guinea, formed about 31 million years ago.

Law followed designation. Lei 07/2006, passed on 13 June 2006, created the Obô Natural Park of Príncipe and set aside 85 square kilometres of southern forest. A 2022 study of the island’s birds shows what that protection has achieved: the discovery of the Príncipe scops-owl lifted the island’s single-island endemic bird species to eight, remarkable for a landmass of just 139 square kilometres.

The rest of the archipelago follows the same logic. The Obô Natural Park of São Tomé covers 195 square kilometres across three separate zones, and scientists ranked the islands’ forests second in biological interest among 75 African forests in 1988. Back on Príncipe, researchers publishing with Cambridge University Press recommended the newly recognised Príncipe thrush, a Critically Endangered species found nowhere else, as the flagship for the whole southern forest. Conservation here has a face that visitors can look for, not only a boundary on a map.

Money came second. When South African entrepreneur Mark Shuttleworth reached Príncipe, the 1,108 hectares of Roça Sundy were slated for clearance to make way for palm oil. His company, Here Be Dragons (HBD), bought the Bom Bom resort in 2011, secured six land concessions covering almost 1,700 hectares, and helped the regional government win biosphere status.

In September 2025, UNESCO extended the designation to São Tomé island, crediting community participation, sustainable land use and conservation.

São Tomé and Príncipe Ecotourism by the Numbers: Small by Design

Volume stays low, and officials say so openly. The islands received 35,817 visitors in 2023 and 40,822 in 2024. Of the 2024 total, 31,422 (77%) were tourists, nearly all arriving by air, and 9,400 were day visitors arriving by sea. The United States rose to second place among source markets with 2,429 tourists (8%), ahead of France with 1,609 and Angola with 1,457.

Arrivals reached about 42,000 in 2025, up 1.2%. The government wants 50,000 by 2030. “We are not a mass tourism destination,” Shellita Viegas, Director-General for Tourism and Hotels, told Lusa in April 2026, adding that the country’s infrastructure could not cope with crowds. Since then, a single airport-collected fee of €25 has replaced the old €2.10 daily charge, with an extra €10 for Príncipe. Lusa reports that the money feeds a national tourism fund, so the fee ties each visitor directly to the sector’s financing.

The economic weight is large for a visitor count this modest. The UN Economic Commission for Africa (ECA) validated the country’s first Tourism Satellite Accounts on 29 October 2025. They show tourism producing 11% of GDP, with international visitors supplying 96% of tourist consumption and staying an average of 18 days. An 18-day stay signals travellers who spend where they sleep. It also explains why the government can afford to cap growth: a visitor who stays almost three weeks leaves more money in a guesthouse, a taxi and a restaurant than three who stay a weekend.

Portugal remains the lead market, which Viegas called “consolidated”. That dependence carries risk. A destination whose largest source market sits one airline route away, and whose African visitors barely register, has a narrow base, however well it protects its forests.

The same accounts expose the weakness. Tourists consumed 3.09 billion dobras of goods and services in 2024, yet national producers supplied only 2.09 billion. About one billion dobras leaked out through imports. The ECA urged the country to diversify its offer around heritage, nature and artisanal products.

Who Carried It: The Ranger, the Turtles and the Estates

Conservation on these islands has names. Ceciliano do Bom Jesus, known as Bikegila, once harvested parrots on Príncipe. Today he is a park ranger, and his local knowledge led scientists to the owl that now bears his nickname. That is who carried it.

The importance is clear on the beaches. The archipelago hosts the last significant hawksbill nesting aggregation in the Eastern Atlantic, according to a 2024 study in Ecology and Evolution. Nine years of nesting surveys and satellite tracking estimated that 482 to 736 green turtles and 135 to 217 hawksbills nest on São Tomé’s beaches. The authors found both species are likely recovering, which they linked to sustained conservation.

Today, that recovery underpins a tourism product. Programa Tatô, founded in 1998, works with Príncipe’s regional government and communities. In 2024, with support from the French Development Agency, it built a Turtle Trail of sculptures from beach waste, made with local artists and youth groups, to tie conservation to visits.

The estates carry a harder story, and the same three questions apply. Roça Sundy began as a cocoa plantation owned by a Portuguese landowner, Jerónimo Carneiro, who showed Eddington’s team the island’s possible observing sites. Eddington’s expedition chose his estate in 1919. The eclipse mattered because it measured a deflection of starlight that matched Einstein’s prediction of 1.75 arcseconds and made Einstein a global figure overnight. Today a stone laid in 1989 and a plaque on the grounds mark the spot, and a 2019 centenary conference brought physicists and residents together on the estate.

Sundy now takes guests as a hotel. Lodges that restore colonial-era buildings owe those guests the history of who built and worked them, not only the cocktail on the veranda. The eclipse site tells a story few destinations anywhere can match, and the islands have barely sold it.

By 2030 the government wants 50,000 visitors. The harder target is ownership. Will the next lodge on Príncipe belong to the island that protects it or to whoever arrives with the next cheque? Until São Tomé and Príncipe answers that, the rest of Africa is copying half a model.
