Backpacking in Derawan Islands
👍 Recommendedregion ranked #14
By Johan Kruseman 🇳🇱 | Updated October 15, 2026

Most travelers don't realize until they arrive that Derawan Islands, off the coast of East Kalimantan in Indonesian Borneo, operates on a completely different pace than mainland Indonesia. You can island-hop without booking weeks ahead, mix reef snorkeling with jungle trekking, and stay in villages where tourism hasn't yet flattened local character. The archipelago delivers raw natural rewards: sea turtles nesting on black-sand beaches, kelp forests thick with fish, and mangrove channels where proboscis monkeys swing overhead. I remember floating above a coral wall at dawn, the water so clear I could count individual fish below me, while a green turtle grazed nearby like it owned the place. The trade-off is real isolation. Derawan demands patience with boat schedules and basic accommodations, but that friction keeps crowds thin and experiences genuine.

✨ Why go?
Ranked #14 region in Indonesia
What makes this region worth visiting

Derawan Islands reward slow travel. The archipelago's scattered layout forces you to stay put and explore deeply rather than rushing between highlights. You can combine reef diving and snorkeling with jungle walks, mangrove kayaking, and village stays without constant relocation. Transport between islands is flexible and affordable, letting you adjust plans based on weather and mood. The region sits far enough from Bali and Jakarta that it attracts fewer backpackers, meaning you'll share dive sites and beaches with locals rather than tour groups. Each island has its own character: Kakaban for jellyfish lakes, Maratua for pristine reefs, Derawan proper for turtle encounters. This variety within a compact area lets you experience multiple ecosystems and cultures in one trip.

💡 HighlightsTop highlights of Derawan Islands

  1. Kakaban Lake: A landlocked saltwater lake on Kakaban Island filled with millions of stingless jellyfish. Swimming among them is surreal and meditative, a rare encounter found nowhere else in Indonesia.
  2. Sangalaki Island: A pristine beach where sea turtles nest year-round and manta rays glide through shallow waters. The island feels untouched, with minimal infrastructure and genuine marine life encounters.
  3. Maratua Atoll: A massive coral ring enclosing a lagoon with dramatic drop-offs and thriving reef life. The atoll's isolation means fewer day-trippers and richer biodiversity than more accessible dive sites.
  4. Derawan Village Jetty at Dawn: Watch fishermen unload the night's catch while the sun rises over the Celebes Sea. This local moment reveals the islands' working rhythm before tourists arrive.

  4. Derawan Village Jetty at Dawn: Watch fishermen unload the night's catch while the sun rises over the Celebes Sea. This local moment reveals the islands' working rhythm before tourists arrive.
  5. Pulu Panjang Snorkel Trail: A shallow reef corridor where you can drift-snorkel through schools of fusiliers and parrotfish without needing a boat or certification. Accessible from Derawan's main island, it rewards effort with minimal logistics.
  6. Tukung Panjang Wreck: A Japanese patrol boat sunk during World War II, now colonized by soft corals and groupers. The wreck sits at 12 to 18 meters, accessible to recreational divers and a tangible piece of regional history.
  7. Samama Island Homestay Community: Stay with local families in simple wooden houses on stilts. You'll eat what they eat, learn to fish their way, and experience the islands without the resort bubble.
  8. Nabire Reef: A steep wall dive with strong currents that attract pelagics and schooling jacks. It's less crowded than Maratua and rewards experienced divers with dramatic marine encounters.
  9. Pulau Semama Turtle Hatchery: A community-run project where you can help release baby sea turtles into the ocean. The work is hands-on and the emotional payoff is genuine.
  10. Derawan's Night Snorkel: Dive at dusk when nocturnal species emerge and bioluminescent plankton glow with movement. Most visitors skip it; those who go see a completely different reef.


I'd start with Kakaban Lake. The jellyfish swim in patterns that feel choreographed, and floating weightless among millions of them is the kind of moment that justifies the travel time to reach these islands.

⌛️ 5 daysA smart one-week plan

Day 1: Derawan:
Arrive at Derawan's main island, the archipelago's transport hub. Most flights land in Balikpapan on Borneo; from there, a 2-hour drive reaches Tanjung Redeb, where speedboats depart for Derawan (1 to 1.5 hours). Settle into the village, walk the jetty at sunset, and let your body adjust to island time. The island is small enough to explore on foot, and the evening light over the Celebes Sea sets the tone for what's ahead.

Day 2: Kakaban and Sangalaki:
Take a guided boat to Kakaban Lake in the morning. Swimming among stingless jellyfish is the archipelago's signature experience and worth the early start. Afternoon boat ride to Sangalaki Island for snorkeling and turtle spotting. The contrast between the lake's surreal calm and the reef's energy defines the islands' range.

Day 2: Kakaban and Sangalaki:

Afternoon boat ride to Sangalaki Island for snorkeling and turtle spotting. The contrast between the lake's surreal calm and the reef's energy defines the islands' range.

Day 3: Maratua Atoll:
Full day at Maratua, either diving or snorkeling the atoll's outer wall and lagoon. The boat ride is 45 minutes to an hour, but the isolation and coral health justify it. Fewer day-trippers reach here, so the reef feels less pressured.

Day 4: Derawan Reefs and Night Dive:
Morning snorkel at Pulu Panjang or a shallow reef near Derawan. Afternoon rest. Evening night snorkel to see nocturnal species and bioluminescent plankton. Most visitors skip this; it transforms how you see the reef.

Day 5: Samama or Tukung Panjang:
Either visit Samama Island's homestay community for a final immersion in local life, or dive the Japanese wreck at Tukung Panjang if you're certified. This day anchors the human or historical side of the islands before departure.

Off-Path Reward: Stay overnight on Samama Island with a local family instead of returning to Derawan each night. You'll eat fresh-caught fish, learn to mend nets, and sleep to the sound of the sea. It costs the same as a guesthouse but feels like a different trip.

Must-Do Day: Day 2 at Kakaban and Sangalaki. The jellyfish lake is irreplaceable, and seeing turtles in their natural habitat on the same day justifies the entire journey.

🌤️ When to go?Best time to visit Derawan Islands

  • Dry Season (May to September): Best window for diving and island travel. Water clarity peaks, boat schedules run reliably, and seas stay calm. Temperatures hover around 28 to 30°C (82 to 86°F). Expect moderate crowds and higher prices.
  • Shoulder Months (April, October): Fewer tourists, still decent weather, and lower accommodation rates. Occasional rain doesn't stop diving, and seas remain navigable. Temperatures 27 to 29°C (81 to 84°F).
  • Wet Season (November to March): Heavy rainfall, rough seas, and frequent boat cancellations. Many operators close or reduce schedules. Temperatures 26 to 28°C (79 to 82°F). Budget travelers find steep discounts, but logistics become unpredictable.
Book boat trips during May to September for reliability; shoulder months offer the best balance of weather and value.

🛏️ Where to stay?Where staying makes the most sense

Derawan Village is the only real settlement on the islands and the base for all exploration. Guesthouses and homestays cluster near the jetty, within a 5-minute walk of boat departures. The village feels lived-in rather than resort-like, with local families running most accommodations. Rooms are basic (fan-cooled, shared bathrooms) but clean, costing US$15 to 30 per night. The social scene centers on guesthouse common areas and the jetty at dawn and dusk.

Samama Island offers homestays with local families for the same price, ideal if you want deeper immersion and don't mind basic facilities. Kakaban and Sangalaki have basic eco-lodges (US$50 to 100 per night), but staying on Derawan keeps costs lower and gives you more flexibility for daily boat trips.

🚌 Getting aroundTransportation options and practical tips

Derawan's main island is walkable end-to-end in 20 minutes, but everything beyond the village requires a boat. Most backpackers rely on speedboats and guided tours arranged through guesthouses or local operators, which is reliable and straightforward.

  • Speedboat Charter: Private or shared boats to nearby islands (Kakaban, Sangalaki, Maratua) cost US$40 to 80 per person for a full day, take 45 minutes to 2 hours depending on destination, and offer flexibility in timing and stops. Comfort varies by boat condition.
  • Guided Snorkel Tours: Organized half-day or full-day trips from Derawan cost US$30 to 60 per person, include equipment and a guide, and run on fixed schedules (usually departing 8 to 9 a.m.). Speed and comfort depend on group size and boat type.
  • Dive Operators: Recreational dives cost

  • Dive Operators: Recreational dives cost US$60 to 100 per dive, include guide and equipment, and depart daily weather permitting. Dives take 3 to 4 hours total. This is the fastest way to reach deeper reefs like Tukung Panjang and Nabire.
  • Shared Minibus from Tanjung Redeb: The 2-hour drive from Tanjung Redeb to the Derawan speedboat dock costs US$8 to 12 per person and runs several times daily. Timing is flexible if you book the night before.
  • Speedboat from Balikpapan: Direct boats from Balikpapan to Derawan (4 to 5 hours) cost US$35 to 50 and run less frequently; arrange through travel agents or your guesthouse.

Book boat trips the evening before or morning of departure. Guesthouses handle arrangements and often negotiate better rates than walk-up bookings. Bring cash; most operators don't accept cards.

🍲 FoodLocal Flavors for Backpackers

Island food centers on fresh seafood: grilled fish, squid, and prawns caught daily by local boats. Rice and noodles form the base of most meals, paired with sambal (chili paste) and simple vegetable sides. Coconut milk flavors curries and soups, while fresh tropical fruit (mangoes, papayas, bananas) appears at every meal. Eat at warung (small family-run restaurants) where locals gather; meals cost US$2 to 4 and taste better than tourist-oriented cafes. Street food includes grilled fish skewers, fried banana, and boiled corn sold from boats and market stalls. Coffee is strong and sweet; ask for it black if you prefer less sugar. Dining customs are casual; eat with your hands or a spoon and fork, and finish your plate to show respect. Fresh water is scarce on islands, so buy bottled water or … read more 👉

FAQCommon questions from travelers

Five to seven days is ideal. Three days lets you hit Derawan, Kakaban, and one other island, but you'll feel rushed. A week gives you time to explore multiple islands, adjust for weather delays, and experience village life without constant boat hopping. Most backpackers spend 5 to 6 days.
Boats are your only option between islands. Shared speedboats and wooden fishing boats connect Derawan, Maratua, Kakaban, and Sangalaki for US$5 to 15 per person depending on distance. Guesthouses arrange pickups from the mainland (Tanjung Redeb) for US$20 to 35. Walking works only within Derawan village itself.
Derawan Islands are known for pristine coral reefs, stingless jellyfish lakes on Kakaban Island, and sea turtle nesting beaches. The archipelago offers world-class snorkeling and diving with minimal crowds, mangrove kayaking, and authentic village stays. It's one of Indonesia's least touristy marine destinations.
⚠️ Things can change over time, so always validate details locally before you go.

We 💚 feedbackIs it worth it?

The Derawan Islands deliver what few Indonesian destinations still do: genuine marine encounters without the resort infrastructure. The catch is isolation. Getting here takes time and planning, and bad weather can trap you for days. Worth it if you're patient and love the sea.

✈️ When did I visit Indonesia?
As part of my 1.5 year travel around the world trip, I visited Indonesia twice (and it was worth it): first in September 2015 and a bit later again in January and February 2016.
