Derawan Islands

Indonesia's hidden diving paradise with pristine coral reefs

Look, most people have never heard of the Derawan Islands. That's exactly why you need to go. This cluster of four tropical islands off East Kalimantan's coast offers some of Indonesia's most pristine diving and snorkeling - without the crowds that swarm Raja Ampat or Komodo. Here's the thing: you'll share these crystal-clear waters with whale sharks, manta rays, and sea turtles that nest right on the beaches. But getting here takes effort, and that's what keeps it special.

Culture & Context

SEA NOMAD CULTURE

Derawan is shaped by two main communities: the Berau people and the Bajo (Bajau), whose ancestors arrived by boat from the Sulu Sea centuries ago. The Bajau are sometimes called sea nomads, and that reputation holds up. Their entire culture orbits the ocean.

Traditional fishing, boat-building, and maritime rituals are still everyday life here, not tourist performances. The island is predominantly Muslim, so the call to prayer rings out across the water five times a day — it's part of the soundtrack. During Ramadan, restaurants may have shorter hours and the pace shifts noticeably.

About 1,000 people live on Pulau Derawan itself, which means shop owners remember your face, boat captains learn your name, and everyone notices when you show up. Confrontation is uncommon here. Raising your voice creates awkwardness fast.

Smiling through misunderstandings is the local protocol, and it actually works. The laid-back pace isn't laziness — it's deliberate.

Local Customs

RESPECT THE SEA

Derawan is a Muslim island. Modest dress matters outside of beach and dive areas. Cover shoulders and knees when walking through the village..

Ask 'sudah makan?' back when locals ask you — it means 'have you eaten?' and it's a genuine expression of care, not small talk.

Engaging with it goes a long way.. The Bajau people have a deep taboo around disrespecting the sea. Don't throw trash in the water.

Don't touch corals. Use reef-safe sunscreen. Locals notice and it matters to them..

Smiling and patience are the real currency here. Boats run late, services are slow, plans change. Getting visibly frustrated makes things worse.

Island pace is real.. There's a turtle conservation site on Sangalaki. Don't touch the turtles, don't use flash photography near nesting sites, and follow the guidance of conservation staff without argument..

Rubbish is unfortunately a real problem on Pulau Derawan's main beach. Multiple travelers report it. Don't add to it, and consider packing out what you can..

If you want quieter island hopping and fewer domestic tourists, travel on weekdays. Weekends and Indonesian public holidays see short bursts of day-trippers from Berau.

Safety

CHECK BOAT SAFETY

Derawan itself is safe. Crime against tourists is not a known issue. But a few things are worth being straight about.

Boat safety in Indonesia broadly is inconsistent — operators may not carry enough life jackets, and equipment maintenance is hit or miss. The Australian government recorded a boat sinking near Bali as recently as March 2026. Research your speedboat operator, check that life jackets exist before departing, and don't board anything that looks obviously overloaded.

Dengue fever peaked nationally in the December 2025–February 2026 rainy season with 89,000 reported cases. Use mosquito repellent, especially at dusk. Drink only bottled water.

There is one ATM on Derawan Island and no advanced medical facilities on the islands — the nearest serious care is back in Berau. Travel insurance that covers medical evacuation is not optional here; it's essential. The US State Department maintains a Level 2 "Exercise Increased Caution" advisory for Indonesia as a whole (terrorism risk, natural disasters) but Derawan specifically has no elevated threat.

Use reef-safe sunscreen — the reefs here are one of the few things genuinely worth protecting, and the Coral Triangle ecosystem is fragile.

Getting Around

SPEEDBOATS & PATIENCE

The gateway airport is Kalimarau Airport (BEJ) in Berau, East Kalimantan. Most travelers connect via Balikpapan (BPN), which has more flight options from Jakarta and Singapore (Scoot serves Balikpapan). From Kalimarau Airport, take a shared taxi or private car to Tanjung Batu Port — that's roughly 2–3 hours of land travel.

Then a speedboat covers the final 30–45 minutes to Pulau Derawan. The longer classic route from Tanjung Redeb harbor takes about 2 hours by speedboat (IDR 250,000 one way), with boats departing roughly every 2 hours from 8am to 4pm. Miss the 4pm boat and you're staying in Berau.

An alternative entry is flying to Tarakan (in North Kalimantan), where direct ferries to Derawan run on Fridays only (IDR 350,000). Public transport in East Kalimantan is unreliable — buses sometimes don't show up. Shared taxis are the more dependable option.

Plan buffer time on both ends of your journey. Everything takes longer than expected, and that's just how it is.

Derawan Island's main beach stretches for 2 kilometers of powdery white sand that feels untouched. The water stays shallow for about 50 meters out, making it perfect for swimming even at low tide. But here's where it gets interesting - green sea turtles nest here year-round, and you'll often spot them surfacing just offshore during evening walks. Maratua Island takes the crown for pure beauty. The lagoon on the island's eastern side creates an almost surreal turquoise pool that's completely protected from waves. Local kids jump off the wooden pier here while their parents fish nearby. The western beaches face rougher seas but offer incredible sunset views. Kakaban Island is different - it's surrounded by a unique brackish lake filled with harmless jellyfish. You can't swim in the ocean here due to strong currents, but the lake experience is unlike anywhere else on earth. Sangalaki Island has the most dramatic coastline with coral cliffs dropping straight into deep blue water.

Money-Saving Tips

  • 1.Book accommodation packages including meals - independent dining options are extremely limited and expensive
  • 2.Bring cash from Berau - there are no ATMs on the islands and card payments aren't accepted anywhere
  • 3.Pack snacks and any dietary requirements from the mainland - island shops have very limited selection
  • 4.Negotiate multi-day boat trip packages rather than paying per trip - you'll save 30-40% on transportation
  • 5.Visit during shoulder season (April or September) for 20-30% lower accommodation rates with good weather

Travel Tips

  • Bring reef-safe sunscreen - the coral here is pristine and chemicals damage the ecosystem
  • Pack a waterproof phone case - you'll want photos of whale sharks and manta rays up close
  • Bring a good underwater camera or rent one in Berau - the marine life encounters are incredible
  • Download offline maps before leaving Berau - internet is spotty and GPS can be unreliable
  • Pack light - boat transfers have weight limits and excess baggage fees are expensive
  • Bring motion sickness medication - boat rides can be rough especially during transitions between seasons

Frequently Asked Questions

No, the snorkeling here is world-class and many of the best experiences like whale sharks and manta rays happen in shallow water. However, certified divers get access to deeper sites with even more marine life.
