Derawan Islands

An archipelago off the northeast coast of Borneo in East Kalimantan, the Derawan Islands are known for extensive seagrass beds that support large populations of green sea turtles, and for jellyfish lakes on Kakaban Island where millions of stingless jellyfish drift in enclosed marine lakes. Manta ray aggregations and whale shark sightings are regularly reported around the islands. The area remains relatively undeveloped despite growing interest from divers.
