East Kalimantan

East Kalimantan is a coastal and offshore region in Indonesia along the Celebes Sea, offering a mix of mangrove-lined coasts, coral flats, and offshore reefs. Diving here tends to be relatively pristine and less crowded, with sites around the coastal city hubs and near the Berau Regency area featuring soft corals, small pelagics, and macro life. Accessibility is largely by boat from regional ports; conditions are typically warm with moderate visibility and seasonally variable currents. Expect a range of shallow to mid-depth sites suitable for recreational divers, with potential drift dives along reef structures.
