Ilhéu Bom Bom
Príncipe Island · São Tomé and Príncipe
The small islet adjacent to Bom Bom resort creates a sheltered channel dive accessible to all levels. Soft corals, wire coral, and juvenile reef fish crowd the rocky walls that slope from 3 m down to 25 m. Moray eels, porcupinefish, and hawksbill turtles are resident year-round. Because the site is close to the main jetty it works perfectly as a night dive, when octopus, cuttlefish, and bioluminescent plankton are consistently encountered.
