Located in the northeast of Sumbawa, this small island is the home of Sangeang Api, one of the most active volcanoes in Lesser Sunda. The presence of this volcano creates volcanic gas bubbles underwater and promises an unforgettable diving experience.

The black sand is the perfect backdrop for the colorful, soft, hard corals and anthias in purple, orange, yellow, pink, and green to dart through the reefs. For macro photography enthusiasts, Sangeang Island offers spectacular sights of pygmy seahorses, frogfish, cuttlefish, nudibranchs, ribbon eels, and various shrimps and crabs.

If you explore the caves and dive deeper off Sangeang Island, do not miss the chance to encounter whitetip and reef sharks.
