About this site
Small Ridge lies off Maratua, one of the islands in the Derawan archipelago off the northeast coast of Kalimantan, Indonesia. This part of the Celebes Sea is dotted with reef and ridge formations reached by boat from the villages around Maratua. The site reaches a maximum depth of around 25 metres and is rated an advanced dive. Divers have also reported venomous sea snakes here, so care around the reef structure is worthwhile.
