About Bom Bom Island
Bom Bom is a small islet off Príncipe, the smaller of the two main islands of São Tomé and Príncipe, about 140 km northeast of São Tomé in the Gulf of Guinea.
Príncipe is volcanic and among the oldest of the gulf's oceanic islands, formed about 31 million years ago, with gentler land in the north and peaks of up to 948 m in the south, where primary rainforest survives. The whole island and its islets, Bom Bom included, form a UNESCO Biosphere Reserve, important for sea turtles, seabirds, whales and dolphins, and coral reefs.
The islets are uninhabited, though a resort stands in the Bom Bom area, set between two sandy beaches. The island's small capital, Santo António, is about 9 km away by road, and a total solar eclipse seen on Príncipe once helped confirm Einstein's theory of relativity.
