Ilhéu das Cabras
A twin-humped islet off São Tomé town, a seabird nesting site.
Updated 16 October 2026
Ilhéu das Cabras sits a few kilometres off São Tomé town, a rocky islet with two humps that is the first thing seen from the waterfront, and it is a protected seabird site: brown boobies and terns nest on it in numbers. Boats run out for diving and snorkelling on the reef around it. Landing is restricted to protect the nesting birds, so most visits stay on the water.
Background
The uninhabited islet sits roughly 2 kilometres from the northeast coast of São Tomé and 8 kilometres north of the centre of São Tomé city. Two hills about 90 metres high make up the islet. A lighthouse built in 1890 stands on the northeastern summit, with a focal height of 97 metres and a range of 12 nautical miles. The islet already appears, as Mooro Caebres, on a 1665 map by Johannes Vingboons.

When to go

Practical notes
Landing is restricted and most trips stay on the water. Boat operations out of São Tomé are limited and must be arranged. Swell cancels crossings.
