Phinisi diving boat at Sangalaki reef
Why 5 days

The minimum that justifies the journey to Berau.

Getting to Derawan from Bali takes one full day of transit (Bali → Balikpapan → Berau → speedboat to Maratua). Three-day packages spend most of that day-1 traveling. By the time you’re settled, the trip is half over.

Five days gives you four full diving days — three at the headline sites (Manta Point, Big Fish Country, Kakaban Lake) plus one for repeats and night dives at Maratua. Returning home with the experience compounded, not rushed.

Day-by-day route.

Day Location Diving + activities
1 Berau → Maratua Speedboat transfer 14:00. Check dive at Maratua house reef. Welcome dinner.
2 Maratua + Kakaban 3 dives Big Fish Country (barracuda tornados). Kakaban jellyfish lake afternoon snorkel.
3 Sangalaki Manta Point morning + afternoon (4 dives). Turtle nesting beach walk at sunset.
4 Sangalaki → Maratua 2 dives Sangalaki west wall. Crossing back to Maratua. Night dive cave.
5 Maratua → Berau Morning dive Maratua Reef Garden. Speedboat departure 12:00.

15-18 dives total over 4 diving days. Captain’s discretion based on conditions and guest certifications.
