Derawan Island travel guidance

Overview

Derawan Island is East Kalimantan's shore-accessible island-stay base for the Derawan Archipelago — a multi-night, boat-dependent trip built around green-turtle viewing right off the jetty, snorkeling and diving day trips to Kakaban and Sangalaki, and an easier, village-life feel than the more diving-focused Maratua, reached via Kalimarau Airport (Berau) and a road-and-speedboat transfer, not a mainland city day trip.

Good to knowTiming matters

Derawan sits inside an official 285,548.95-hectare marine conservation area (KKP3K-KDPS, established by national decree in 2016), so several nearby islands you will hear about — Kakaban and Sangalaki — are day-trip stops rather than places you would plan to overnight: Kakaban has no accommodation at all, and Sangalaki carries two independently-operated dive resorts/lodges that this page's sources describe, though neither is presented as a general stay option in place of Derawan or Maratua. The standard access chain is a flight to Kalimarau Airport (BEJ) in Tanjung Redeb, a road transfer of roughly two hours to Tanjung Batu port, then a speedboat crossing of about 30 minutes to the island; flight schedules and boat departure times are airline- and weather-dependent (visibility/haze has disrupted Kalimarau flights before) and worth confirming close to travel rather than treated as fixed. Kakaban's jellyfish lake has posted entry rules — wash gear before entering, no sunscreen or insect repellent, no fins, no scuba diving — that can change; confirm the current rules with your operator before your visit. Entrance fees for Kakaban and Sangalaki vary across sources and visitor categories, so this page does not state a fee. Turtle nesting follows a roughly March-to-October pattern and manta sightings at Sangalaki are reported across the year, but neither is guaranteed on any given day. Travelers building a longer trip sometimes add a mainland whale-shark day trip at Talisayan or a visit to Labuan Cermin's mirror lake near Biduk-Biduk; both require a pre-dawn or long overland departure from the Berau/mainland side and are optional add-ons, not part of the core island stay.

Experience

What it's like

Derawan Island is a single practical stay base — there is no second in-town area to compare it against, so this page does not present a Stay comparison tab. Accommodation ranges from simple fan-room homestays with shared bathrooms, through air-conditioned guesthouses, to overwater or beach cottages and villas; exact nightly rates shift often enough that this page does not state a fixed figure. Trip length on Derawan itself varies with dive/wildlife goals, sometimes combined with one or more nights on Maratua for travelers who also want wall/channel diving — see the Maratua page for that comparison. Kakaban has no accommodation of any kind, so every visit is a day trip launched from your Derawan (or Maratua) base. Sangalaki carries two independently-operated dive resorts/lodges offering direct overnight stays on the island itself — narrow, single-purpose options built around diving rather than a general destination stay — but every other source this page found still describes a Sangalaki visit as a day trip from Derawan or Maratua, not a second stay base to plan around; see the Sangalaki entry below.

Areas to know

These are reference descriptions of areas within Derawan Island — not a stay comparison.

Tanjung Redeb (Berau) — The Berau Regency capital and the practical logistics base for the whole archipelago — airport arrival, vehicle and boat-crew staging, and the regional tourism department's own office. Not an independent multi-night stay destination on the evidence available; it functions as a transfer point rather than a stay to plan around, though an unplanned overnight is possible if your flight and boat schedule don't align.
Tanjung Batu — The small port village where road transfers meet island speedboats, roughly two hours from Kalimarau Airport. The regency government opened a Tourism Information Center at the jetty in 2025 for passengers and local small businesses; it is a transfer point, not an overnight stay destination.

Conservation area and permits

Derawan and its surrounding islands sit inside an official 285,548.95-hectare marine and coastal conservation area (KKP3K-KDPS), established by national ministerial decree in 2016 and managed through an East Kalimantan provincial technical unit under a 2024 governor regulation — an actively evolving governance structure, not a fixed arrangement. Entrance fees for Kakaban and Sangalaki vary across sources and visitor categories, so no fee figure is stated here; confirm current pricing with your operator or on arrival.

Fit and constraints

This is a boat-dependent, island-based trip: connectivity, healthcare access, and amenities are more limited than on the Kalimantan mainland, and every inter-island movement depends on sea conditions and an arranged boat. None of this rules the trip out — the route is well established with experienced local operators — but it is worth assessing honestly against your own comfort with boat-based days and a more remote setting before booking.

Things to do

Derawan Island (shore and reef) — Green turtles are reported swimming close to the jetty and shoreline, and reef snorkeling is accessible directly from the island. Wildlife sightings are never guaranteed on any given visit.
Kakaban Island (day trip) — A landlocked brackish lake holding a population of jellyfish that lost most of their sting through long isolation from the open sea — a half-day stop on many itineraries. Entry rules include washing gear before entering, no sunscreen or insect repellent, no swim fins, and no scuba diving; the official tourism registry does not list a general swimming prohibition. Access rules for the lake are set by local and provincial authorities and can change — confirm the current rules before your visit.
Sangalaki Island (day trip) — An official nature reserve (Taman Wisata Alam) managed by the national forestry conservation authority (BKSDA), which patrols the island and manages visitor access. Two independently-operated dive resorts/lodges operate directly on the island for divers who want to stay at the dive sites overnight, but every other source this page found frames a Sangalaki visit as a day trip from Derawan or Maratua, not a base for planning a multi-night stay around. Visited for manta-ray encounters and as a turtle-nesting site; manta sightings are reported across the year but never guaranteed, and turtle nesting follows a roughly March-to-October pattern rather than a fixed schedule.
Talisayan whale sharks (optional mainland add-on) — A mainland site near fishing platforms (bagan) where whale sharks are sometimes encountered; reaching it requires a pre-dawn departure from the Berau/mainland side and realistically needs a longer trip (commonly four nights or more) to fit comfortably. Sightings are never guaranteed — several operators explicitly decline to promise them.
Labuan Cermin (optional mainland add-on) — A two-layer fresh/saltwater lake near Biduk-Biduk, a different Berau sub-district reached by a separate long overland trip from Tanjung Redeb. Some longer, multi-stop itineraries bundle it in; it sits outside the direct Tanjung Batu/Derawan boat corridor and is a distinct add-on decision, not part of the core island stay.

Plan your visit

When to go

Tourism sources describe a calmer-crossing window running roughly April through November, when sea conditions for the inter-island speedboats are generally more settled; the shoulder months outside that window can bring rougher water and a higher chance of a lost or shortened boat day. Manta sightings at Sangalaki are reported across the year rather than tied to one season, while turtle nesting follows a broader March-to-October pattern. Treat both as directional patterns to plan around, not a guarantee for any specific date, and confirm current sea-condition advice with your operator close to travel.

Getting there & around

Getting there

Fly into Kalimarau Airport (BEJ) in Tanjung Redeb, the capital of Berau Regency — the shorter-crossing gateway, served by routes from Balikpapan, Jakarta, Surabaya, Samarinda, and Makassar, though schedules and frequencies are airline-set and occasionally disrupted by weather (visibility/haze has grounded Kalimarau flights before), so confirm close to travel. From the airport, a road transfer of roughly two hours reaches Tanjung Batu, the small port village that faces the archipelago, followed by a speedboat crossing of about 30 minutes to Derawan Island. An alternative gateway exists via Tarakan (TRK) in North Kalimantan, with a considerably longer three- to four-hour speedboat leg; it can make sense for travelers already in Tarakan or crossing from Sabah. Boat departures depend on your operator and daylight/sea-state windows rather than a fixed public timetable, so confirm your transfer and boat arrangements before you arrive — an afternoon flight arrival with no boat arranged can mean an unplanned overnight in Tanjung Redeb.

Getting around

Derawan Island itself is small and mostly walkable along its village paths and jetty area. Getting to anywhere else in the archipelago — Kakaban's jellyfish lake, Sangalaki's manta site, or Maratua — means a chartered or shared speedboat, arranged either directly with a boat operator or bundled into an accommodation/tour package. There is no scheduled public ferry network between the smaller islands; trip timing depends on your operator and sea conditions.

Your trip

How Derawan Island fits your trip

May suit travelers who want a boat-dependent, marine-wildlife-focused island stay — shore-accessible turtles, reef snorkeling, and manageable day trips to Kakaban's jellyfish lake and Sangalaki's manta site — without needing to commit to Maratua's more advanced wall/channel diving; a fit for mixed groups, families with older children, and newer divers.
