Mantas, turtles, and a stingless jellyfish lake in a remote Coral Triangle corner of Borneo
Updated Dec 13, 2025 • 12 sources
Derawan is remote and current-influenced. Dive conservatively, follow local briefings, and treat insurance and emergency planning as essential. Conservation etiquette is equally important: manta and turtle encounters are a privilege, and the region's reefs and lakes are sensitive.
Medical facilities on the islands are limited to small clinics. Serious cases typically route back to Berau mainland and onward to larger hospitals. Operator materials for the Derawan area commonly cite Balikpapan as the nearest established recompression chamber location, with travel time potentially very long from the islands. Some resort documents also mention a newer chamber in the Tanjung Batu area that may be available.
Practical takeaways:
Strong currents and downcurrents at points
Some sites are tide-driven and can run fast. Stay close to your guide, carry an SMB, and skip exposed corners if you are not comfortable.
Remote medical logistics
Medical facilities on the islands are limited, and recompression may require long transport. Dive conservatively and keep insurance details accessible.
Surface chop on boat crossings
Speedboat rides can be bumpy in wind and rain. Pack dry bags, protect camera gear, and consider seasickness medication.
Mosquito-borne illness risk
Use repellent and cover up at dusk, especially in wetter months. Sleep under nets where provided.
Derawan is widely described as a marine conservation region and includes areas formally designated as the Berau MPA.
Support conservation-positive operators, respect community-managed fees, and remember that many sites are tied to local livelihoods.
Do Not Do This
Avoid entering when strong currents and downcurrents at points. Confirm local briefings before committing.
