You drop into the jellyfish lake and they're everywhere — pulsing golden spheres, thousands of them, brushing past your arms, your mask, your fins. They're stingless. You float motionless among them as the sun shafts through the water and the jellies drift like living lanterns. Back on Derawan, green turtles haul themselves onto the beach at night to nest, and the wooden stilt walkways over the reef become viewing platforms for reef sharks cruising the shallows.

The Derawan Islands are an archipelago in East Kalimantan comprising 31 islands, with Derawan, Kakaban, Sangalaki, and Maratua as the primary destinations. Kakaban Island contains a landlocked marine lake with four species of non-stinging jellyfish — one of only a handful of such lakes worldwide (alongside Palau's Jellyfish Lake and lakes in Vietnam and Indonesia's Togian Islands). Sangalaki hosts one of Indonesia's most significant green sea turtle nesting sites, with females laying eggs on the beach nightly during season. Maratua's reef system features dramatic walls, caves, and a resident population of barracuda in enormous schools. Diving conditions include strong currents suited to experienced divers. Access is via Berau (flights from Balikpapan), then a 2-hour speedboat to Derawan Island. Accommodation ranges from basic island homestays to the overwater resort on Maratua.
