Derawan, Sangalaki & Kakaban, Indonesia – Mantas, Turtles & Jellyfish Lake Expedition
A remote Indonesian island journey combining manta sites, turtle-rich reefs, Kakaban’s extraordinary jellyfish lake, wall diving and a true expedition atmosphere.
Derawan, Sangalaki and Kakaban feel like a lost corner of Indonesia: turquoise water, remote islands, turtles, mantas and one of Southeast Asia’s most unusual natural experiences.
Each island has its own personality: Derawan for turtles, Sangalaki for mantas, Kakaban for walls and jellyfish lake, and nearby Maratua for more adventurous current diving.
This is not mass-market Indonesia. For the right clients, it feels like a secret world — wild, beautiful, remote and different.

Underwater Photography in Derawan, Sangalaki & Kakaban
This region is strongest for wide-angle and travel-style underwater photography: mantas at Sangalaki, turtles around Derawan, walls at Kakaban and current-fed scenes around Maratua.
Macro can also be useful around jetties, rubble sites and night dives, especially at Derawan Jetty and similar structure-focused areas.
For photography-focused groups, the best experience comes from flexibility. Manta sightings, visibility and current conditions vary, so the programme should allow enough time for repeat attempts, weather buffers and a mix of wide-angle, macro and topside island photography.

For Non-Diving Companions
Derawan, Sangalaki and Kakaban can work for non-diving companions who enjoy nature, remote islands and simple tropical experiences. The strongest non-diver highlight is Kakaban Jellyfish Lake, usually experienced as snorkeling or a nature visit.
Other activities may include turtle watching, island hopping, beaches, snorkeling, village visits and photography. This is not a polished luxury-everywhere destination; it is better for guests who enjoy remote places, nature and a more expedition-style rhythm.

Responsible Manta, Turtle & Jellyfish Lake Encounters
Mantas and turtles must be observed respectfully. Divers and snorkelers should never chase, touch, block or crowd animals, and should allow wildlife to control the encounter.
Kakaban Jellyfish Lake should be treated as a fragile natural environment. Coral Triangle Expeditions supports careful planning, respectful photography, excellent buoyancy and low-impact visits that protect the region’s marine and island ecosystems.
