Wall and drop-off diving
The reef edge falls away sharply: one dive moves from bright coral shallows to deep blue in a few fin kicks.
Destinations · Nabucco
A very small island on the outer rim of the Maratua atoll, known almost entirely for diving: a reef wall and channel water on its doorstep.
Where it is
Nabucco Island is one of the small islets on the rim of the Maratua atoll, close to Nunukan Island, in Berau Regency, East Kalimantan. You can walk its shoreline in a few minutes, and there is no town, market or public transport.
Its relevance to travellers is the reef wall and channel water on its doorstep, which is why it appears on dive maps more often than on tourism maps. Every visit is a boat movement inside the Maratua area.
For most travellers it is a specialist stop rather than a trip in itself. If you want the atoll wall and channel, it belongs on a shortlist with Nunukan and Maratua; for a first broad look, Kakaban, Sangalaki and Derawan fill the days more completely.
Underwater
The attraction is underwater. The Maratua rim is a wall system where reef shallows drop steeply into deep blue water. Most recreational dives run between about 5 and 30 m.
Getting there
Every practical route runs through Berau. Our meeting point is Kalimarau Airport (BEJ).
| Leg | Mode | Approximate time |
|---|---|---|
| Your own flight to Kalimarau (BEJ), Berau | Flight, booked by you | Depends on your flight |
| Kalimarau Airport to Tanjung Batu | Road transfer | ~2.5 to 3 hours |
| Tanjung Batu to Derawan Island | Speedboat | ~40 minutes |
| Derawan to the Maratua atoll (Nabucco and Nunukan area) | Speedboat | ~1.5 hours |
Sea legs are weather-dependent. Boat times are normal-condition estimates, and a captain who delays a crossing for swell is doing his job correctly.
Nabucco Island Resort
Nabucco Island is associated with dive-resort operation, and we keep a separate reference page for that search. We will not publish a room count, star rating, facilities list, certification claim or reviews for a property we do not operate and cannot verify in writing.
Nabucco is not one of the 13 destinations on our trips and not a stay we book: we do not sell trips to Nabucco. Our itinerary covers:
Where our guests sleep
If being on Maratua rather than on Derawan matters to you, choose a Maratua stay: you choose the stay, and the price depends on it.
Private Trip Derawan rates from indonesiajuara.asia: total for two guests, standard tier.
When to go
April to November is the best season, chosen for sea conditions. December to March is the wetter period, when the crossings between Derawan and the Maratua atoll are less reliable, though trips still run. Inside the best season, months differ in visibility and swell; turtles are resident year-round.
Our private trips run 3D2N or 4D3N from Kalimarau Airport, with a minimum of two guests. On both, day two covers Maratua, Kakaban and Sangalaki.
