As of September 2026, no seaplane operator publishes a fixed cost per person for a Berau-to-Derawan charter — pricing is quoted per flight (aircraft, block time, positioning, permits), then divided by however many travelers fill the seats, so the same charter can land anywhere from a premium solo fare to a modest per-head rate with a full plane. Ask for a dated, written quote rather than a listed price.
That answer will disappoint anyone hunting for a simple number, but it is the honest one. Nobody selling access to Kepulauan Derawan, Maratua, Kakaban or Sangalaki by seaplane has a public rate card, and Juara Holding Group will not invent one. What follows is what actually determines the figure you will eventually see on a quote, plus what comparable Derawan transport costs today so you have a real anchor while you wait for that number.
Why Isn’t There a Published Seaplane Fare for Derawan?
Kalimarau Airport (BEJ) in Berau is the documented gateway to the archipelago, reached via connecting flights through Balikpapan or Tarakan. From there, the standard route to the islands is road plus speedboat — about 2 to 2.5 hours by road from Kalimarau to the Tanjung Batu jetty, then 30 minutes to Derawan, roughly 1 hour to Kakaban, and about 2 hours to Maratua or Sangalaki by boat. Maratua is the only island with an airstrip, served by Wings Air twice weekly; Derawan, Kakaban and Sangalaki have no airport at all.
A seaplane changes that math by landing on water near the island itself, but no source names an operator running Berau-Derawan seaplane service, a designated water-landing site, or a water aerodrome regulation for East Kalimantan as of September 2026. A water landing on this route would be subject to operator approval, aviation authority permits, and conditions on the day — not a scheduled service with a printed fare. That is exactly why the “cost per person” only exists once a specific date, aircraft and group size are confirmed.
What Actually Drives a Derawan Seaplane Charter Quote?
Every charter quote is built from a small set of variables. Understanding them tells you more than a fake price ever could.
| Cost Driver | What It Affects | Why It Moves the Per-Person Number |
|---|---|---|
| Aircraft size (seats) | Total charter cost ÷ seats filled | A 6-seat aircraft splits the same flight cost among fewer people than a 10-seat aircraft |
| Route distance (Berau to island) | Flight time, fuel burn | Derawan and Maratua sit close together; a longer detour to Sangalaki or Kakaban adds air time |
| Waiting/ground time | Aircraft positioning, crew hours | A same-day return charter costs less than one where the aircraft waits hours on the water |
| Weather rerouting | Contingency planning, possible delay days | Coastal weather can force a delayed departure or an alternate landing point, added to the quote as a contingency line |
| Gear and baggage weight | Payload limits, possible extra rotation | Dive gear, underwater camera rigs or group luggage can push a light aircraft past payload and force a second run |
| Group size | Per-seat division | The same flight quoted for 2 people costs far more per head than for 6 |
None of these line items has a public rate in Berau as of September 2026. They are listed here so you can ask informed questions when you request a quote, not so you can estimate a total yourself.
What Do Verified Derawan Transport Alternatives Cost Today?
While seaplane pricing stays quote-only, several Derawan transport and charter options do have documented, dated figures. These are not seaplane prices — they are the closest verified benchmarks for reaching or exploring the same archipelago, useful for budgeting context.
| Option | Verified Price | Source / Date |
|---|---|---|
| Open-trip Derawan package (private, 2-traveler minimum) | From USD 281 per person | Indonesia Juara, page updated 17 Aug 2026 |
| Taxi + boat, Berau to Sangalaki | quoted on request | Scuba Junkie Sangalaki listing |
| Open Trip Derawan 3D2N deposit | IDR 500,000 per person | Open-trip listing, updated 29 Apr 2026 |
| Derawan phinisi charter | quoted on request | LuxuryPhinisi listing |
| Seaplane charter, Berau to Derawan/Maratua | Quote on request | No published rate as of Sept 2026 |
All figures above are dated and subject to change; none of them is a seaplane rate, and none should be read as a discount or ceiling on what a seaplane charter will eventually cost. They exist to show you what “getting to Derawan” costs by the routes that do have public numbers.
How Does the Deposit, Currency and Fuel Surcharge Work?
A charter quote, once issued, typically has three moving parts worth understanding before you ask for one:
- Deposit. Boat-based Derawan trips in this region use deposits as low as IDR 500,000 per person to hold a date; a private charter — seaplane or boat — usually asks for a larger percentage of the total quoted price to lock the aircraft and crew for your date. The exact figure is set per quote, not fixed in advance.
- Currency. Quotes in this market are issued in either IDR or USD depending on the operator and the traveler’s origin. Confirm which currency your figure is in before comparing it to anything else, since a Rupiah quote and a Dollar quote are not interchangeable without a same-day conversion check.
- Fuel surcharge. Aviation fuel pricing moves independently of the base charter rate. A quote may separate a fuel surcharge line so it can be adjusted close to your flight date rather than baked into a number that goes stale. Ask whether your quote is fuel-inclusive or subject to a surcharge at time of departure.
What’s Excluded From a Derawan Seaplane Charter Quote?
Expect these to sit outside the base charter figure unless your quote states otherwise: domestic flights into Kalimarau (BEJ) via Balikpapan or Tarakan; ground transfer and lodging on the islands; park or conservation entry fees for Kakaban, Sangalaki or Maratua dive sites; dive or snorkel equipment rental; meals beyond what the quote specifies; and travel insurance. A dated quote from the coordination desk will itemize what is and is not covered for your specific date and group size.
How Does Booking a Derawan Seaplane Charter Work?
- Share your dates and group size. Message the coordination desk with your preferred travel window (April to November is the season referenced for regional Derawan trips) and the number of travelers.
- Receive a dated, itemized quote. Expect aircraft type, route, estimated block time, deposit amount, currency and what is excluded — never a generic listed price.
- Confirm feasibility. Because no fixed water-landing site is documented for this route as of September 2026, your quote will note that the charter is subject to operator and authority approval on the day.
- Pay the deposit to lock the date. Terms are set per quote, in the currency stated.
- Reconfirm 48-72 hours out. Weather and payload (gear, luggage) are checked again before departure; a reroute or ground alternative is discussed if conditions require it.

Frequently Asked Questions
Why can’t I just get a fixed price per person for a Derawan seaplane charter?
Because charters are billed per flight, not per seat — the total covers the aircraft, crew, fuel and positioning regardless of headcount, then that total is divided by however many travelers are on board. Until your group size and date are set, there is no single number to quote, which is why every credible answer is “request a dated quote,” not a listed fare.
How many travelers does it take to bring the seaplane cost per person down?
There’s no published seat-price to calculate from, but the principle is straightforward: filling more of the aircraft’s available seats spreads the same flight total across more people. A 2-traveler charter and a 6-traveler charter on the same aircraft will have very different per-person figures even though the flight itself costs roughly the same to run.
Should I budget in IDR or USD for a Derawan seaplane charter?
Either currency is used in this market, and your quote will state which one applies. Check the currency on your specific quote before comparing it to another figure — a number in Rupiah and a number in Dollars are not directly comparable without converting at the day’s rate, and the coordination desk will confirm the exchange context when the quote is issued.
What’s a realistic budget if the seaplane charter isn’t quoted yet?
Use verified boat-based benchmarks as a floor, not a substitute: private Derawan trips from Indonesia Juara start at USD 281 per person with a 2-traveler minimum (as of 17 Aug 2026), while a Derawan phinisi charter runs from a price quoted per case on request per night per LuxuryPhinisi. A seaplane charter, once quoted, will sit above standard boat transfer pricing given the aircraft, crew and permit requirements involved.
Does the quote include getting to Kalimarau Airport itself?
No. The seaplane charter quote covers the flight from Berau to the islands (Derawan, Maratua, Kakaban or Sangalaki), not the domestic flight into Kalimarau Airport (BEJ) via Balikpapan or Tarakan. Book that inbound leg separately, and factor its schedule into the seaplane charter timing you request from the coordination desk.
