When it comes to tropical island paradises, Indonesia is filled with well-known spots like Bali, Lombok, and the Gili Islands. But hidden away in the province of East Kalimantan (Borneo) lies the Derawan Islands, an untouched archipelago that is still largely unknown to mainstream travellers.
With crystal-clear waters, vibrant coral reefs, a peaceful atmosphere, and the unique experience of swimming in a jellyfish lake, the Derawan Islands offer a slice of Indonesia that feels wild, authentic, and wonderfully serene.
Why Visit the Derawan Islands?
The Derawan Islands are perfect for those looking for off-the-grid beauty, spectacular diving, and intimate encounters with marine life. Unlike the busier islands in Indonesia, Derawan remains unspoiled, with local fishing villages, secluded beaches, and some of the most biodiverse waters on the planet.
The islands are part of the Coral Triangle, which is considered the global centre of marine biodiversity.
Top Things to Do in the Derawan Islands
1. Swim in the Jellyfish Lake (Kakaban Island)
One of the biggest highlights of the Derawan Islands is Kakaban’s jellyfish lake, a unique body of water where you can snorkel safely among thousands of non-stinging jellyfish.
The lake is isolated from the sea and is home to four species of jellyfish that have evolved to lose their sting. It’s a surreal experience to float among these graceful, otherworldly creatures.

2. Diving and Snorkelling with Giant Turtles
Derawan’s waters are teeming with life, and one of its most magical experiences is diving or snorkelling alongside giant green sea turtles. These gentle creatures are commonly seen just offshore, and it’s not unusual to spot several in a single dive.
Top dive sites include:
- Sangalaki Island: Known for manta rays and rich coral reefs.
- Kakaban Island: Offers wall dives and stunning coral gardens.
- Derawan Island: Home to frequent turtle sightings and beautiful shallow reefs.
3. Spot Whale Sharks at Talisayan
One of the rarest and most rewarding encounters in the region is swimming with whale sharks at Talisayan. Local fishermen attract these gentle giants near fishing platforms, and snorkellers can enter the water to see them up close.
It’s a breathtaking, humbling experience to float just metres away from the world’s largest fish.
4. Relax on Secluded Beaches
The Derawan Islands are blessed with soft white-sand beaches and crystal-clear lagoons. Unlike other touristy islands, here you’ll often find yourself completely alone on the beach.
Spend your days swimming, sunbathing, and enjoying the peaceful rhythms of island life.
5. Experience Local Island Culture
Derawan Island itself is home to a small fishing community where you can wander through colourful wooden houses, try fresh seafood, and interact with friendly locals who live far removed from the bustle of Indonesia’s larger cities.
Where to Stay
Accommodation in the Derawan Islands ranges from:
- Simple Guesthouses: Family-run, budget-friendly, and right on the beach.
- Overwater Bungalows: Affordable, basic, and perfect for falling asleep to the sound of the sea.
- Dive Resorts: Offer packages that include dives, equipment, and meals.
Derawan’s charm lies in its simplicity—don’t expect luxury, but do expect unforgettable natural beauty.
Getting to the Derawan Islands
- Fly to Berau (Kalimaru Airport): From Jakarta or Balikpapan.

For travellers seeking real adventure, rich marine life, and tranquil island living away from the crowds, Derawan is a hidden gem that’s well worth the journey.
