Travelers from Balikpapan or Samarinda reach the Derawan archipelago via Kalimarau Airport (BEJ) in Berau — Balikpapan has documented flight connections to BEJ, while Samarinda travelers usually route through Balikpapan first. From BEJ, plan roughly 2 to 2.5 hours by road to Tanjung Batu, then 30 minutes to 2 hours by boat depending on the island.
Why Does Every Route Funnel Through Berau?
Kalimarau Airport sits in Teluk Bayur district, Berau Regency, East Kalimantan, and every documented route into Derawan, Maratua, Kakaban and Sangalaki passes through it — a 2019 Liputan6 report already named BEJ the tourism gateway to these islands. There is no shortcut that skips Berau. Balikpapan and Samarinda are starting points, not endpoints, and the itinerary only really begins once a traveler lands at BEJ or drives into Tanjung Redeb, the regency capital.
That matters for planning because the two cities behave differently as jumping-off points. Balikpapan (BPN) has a documented domestic flight connection to BEJ, which makes it the more predictable hub. Samarinda does not appear in the public routing data reviewed for this piece as having a direct scheduled flight to Berau, so travelers starting there are better served checking current airline listings directly or simply treating Balikpapan as their real launch point, whether that means flying BPN to BEJ or driving the overland corridor between the two East Kalimantan cities first.
How Do You Get From Balikpapan to Berau?
The cleanest path from Balikpapan is a domestic flight to Kalimarau Airport. Once on the ground at BEJ, the next leg is road transport to Tanjung Batu, the usual jetty for speedboats into the archipelago — that drive runs about 2 to 2.5 hours, with one itinerary quoting up to 3 hours depending on traffic through Berau town and road conditions along the coast. From Tanjung Batu, a speedboat to Derawan itself takes about 30 minutes, making Derawan the fastest island to reach once you are off the plane.
Travelers heading to Kakaban instead should budget about 1 hour by speedboat from Tanjung Batu, and those continuing to Maratua or Sangalaki should plan for roughly 2 hours on the water. None of these numbers include waiting time at the jetty, boat departure schedules, or the walk from the airport curb to whatever vehicle is arranged — all of which push a same-day arrival closer to its outer limit than its optimistic one.
How Do You Get From Samarinda to Berau?
As of September 2026, no direct scheduled commercial flight from Samarinda to Berau shows up in the airline routing reviewed for this article. That does not mean one will never exist — regional schedules in East Kalimantan change, and it is worth checking current listings before booking anything. Until then, the practical move for a Samarinda-based traveler is to treat Balikpapan as the real gateway: either drive the overland link between Samarinda and Balikpapan and fly BPN–BEJ from there, or fly Samarinda to Balikpapan first if a short domestic hop is available on the day you are traveling, then connect onward to BEJ.
Balikpapan to Derawan seaplane charter arrangements are one way some travelers try to shorten this multi-leg routing, since a private charter can, in principle, collapse the flight-plus-road-plus-boat sequence into fewer transfers — though as of September 2026 no seaplane operator, water-landing site, or per-hour rate for a Berau route is publicly documented, so any seaplane leg should be treated as quote-on-request and confirmed directly with a coordination desk before it is built into an itinerary.
Balikpapan and Samarinda Starting Points vs Berau Arrival Windows
| Starting point | Realistic leg to Berau | What you land into | Same-day island arrival? |
|---|---|---|---|
| Balikpapan (BPN) | Domestic flight to Kalimarau Airport (BEJ) | BEJ terminal, then 2–2.5 hrs road to Tanjung Batu | Usually yes, for Derawan |
| Samarinda | No direct BEJ flight documented; overland or connecting flight via Balikpapan first | BPN or Berau town, then the same road-to-jetty sequence | Only with an early departure |
| Balikpapan or Samarinda, late departure | Flight or drive arriving BEJ/Berau after midday | Tanjung Batu jetty near or after last boat departures | Often no — overnight likely |
What Happens Once You Land at Kalimarau Airport?
Landing at BEJ is the midpoint of the trip, not the end of it. From the terminal, the standard sequence is a road transfer to Tanjung Batu, then a speedboat onward. Tanjung Redeb, the regency capital, also has a harbour used by public and charter boats, and a public speedboat leaves Tanjung Redeb pier around 10:00 heading direct to Maratua, arriving in about 2.5 hours — a useful fallback if a private boat from Tanjung Batu is not arranged. Separately, one dive-travel source lists Tanjung Redeb harbour boats to Maratua, Sangalaki or Kakaban departing as early as 08:00 and as late as 16:00, roughly 2 hours each way.
The practical takeaway is that Berau has two viable boat launch points — Tanjung Batu and Tanjung Redeb — and which one a traveler uses depends on how their road transfer from BEJ is arranged and which island they are headed to first.
Berau to Island Boat Times at a Glance
| Route | Typical duration | Notes |
|---|---|---|
| Tanjung Batu → Derawan | About 30 minutes | Fastest hop from the mainland jetty |
| Tanjung Batu → Kakaban | About 1 hour | Kakaban has no airstrip; boat only |
| Tanjung Batu → Maratua or Sangalaki | About 2 hours | Maratua is the only island with an airstrip (Wings Air, twice weekly) |
| Derawan → Kakaban | About 1 hour | Common island-to-island hop once based on Derawan |
| Tanjung Redeb pier → Maratua (public boat) | About 2.5 hours, ~10:00 departure | Alternative to the Tanjung Batu route |
Where Does an Overnight Become Unavoidable?
Door-to-jetty for Derawan via Berau totals roughly 3 hours once a traveler is on the ground at BEJ — that arithmetic works cleanly for a morning flight into Kalimarau, but it falls apart fast for anyone landing in the afternoon. Public boats from Tanjung Redeb run on a defined window, first departure around 08:00 and last around 16:00 according to the dive-travel schedule referenced above, and private speedboats from Tanjung Batu are not running around the clock either — daylight, tides and operator availability all narrow the window further.
That means a Balikpapan traveler on a midday or later flight into BEJ, or a Samarinda traveler whose overland connection eats most of the morning, should plan on an overnight in Berau — either in Tanjung Redeb or near the airport — rather than gambling on catching a same-day boat. Maratua and Sangalaki, at roughly 2 hours by water from Tanjung Batu, are the least forgiving legs on a tight afternoon connection; Derawan, at about 30 minutes, has the most cushion.
What Mistakes Do Travelers Make on Connection Timing?
The recurring mistake is booking a same-day flight-to-boat connection without checking the boat’s own schedule first — a flight that lands at BEJ mid-afternoon can still miss the last public departure from Tanjung Redeb or run into a private boat operator who has already closed the day’s crossings. A second mistake is assuming Samarinda has the same flight access to Berau that Balikpapan has; as of September 2026 that direct link is not documented, so building an itinerary around it risks a missed or nonexistent connection.
A third mistake is underestimating the Kalimarau-to-Tanjung Batu road leg. Quoted times range from 2 to 3 hours depending on the source, and traffic through Berau town, road works, or a delayed pickup can push a “2-hour” transfer toward the top of that range — which then chews into whatever boat window remained. Finally, travelers heading specifically to Maratua sometimes assume the island’s twice-weekly Wings Air service solves their timing problem; it only does so if the flight day and the traveler’s dates actually line up, and outside that narrow window the boat route from Tanjung Batu or Tanjung Redeb is still the only way in.
Can a Seaplane Fit Into This Route?
Small-aircraft arrivals into the archipelago are practiced — Green Nirvana Resort itself describes reaching the islands “by boat or small airplane” after landing at BEJ — but no source names a seaplane operator, a designated water-landing site, a water aerodrome, or any government priority status for water landings in East Kalimantan. Any seaplane leg for a Balikpapan-or-Samarinda itinerary should be treated as subject to operator approval, authority permits and conditions, with no designated water aerodrome documented as of September 2026, and priced only on quote-on-request terms rather than a published fare. Juara Holding Group operates as an independent coordination desk, established 2015, that arranges charters and transfers with licensed Indonesian operators — it owns no aircraft and is not affiliated with any named operator, so a seaplane leg on this route is coordinated with a partner operator on a case-by-case basis via WhatsApp at 6281139414563 or bd@juaraholding.com.
Frequently Asked Questions
Is it faster to fly Balikpapan–Berau or drive from Samarinda?
Flying Balikpapan to Berau is faster and more predictable, since BPN has a documented flight connection to Kalimarau Airport. Samarinda has no direct documented flight to Berau as of September 2026, so a Samarinda departure usually means an overland leg to Balikpapan or a connecting flight first, adding hours a direct Balikpapan-to-BEJ flight avoids entirely.
Can I reach Derawan the same day I leave Balikpapan or Samarinda?
Yes, if you catch a morning flight into Kalimarau Airport and the road-to-jetty transfer runs on schedule — door-to-jetty for Derawan is roughly 3 hours from BEJ, and the boat crossing itself is only about 30 minutes. A midday or later arrival narrows the window sharply and often forces an overnight in Berau instead.
Do I need to book the Tanjung Batu boat in advance, or can I just show up?
Public boats from Tanjung Redeb run on a known window, roughly 08:00 to 16:00 departures, but private speedboats from Tanjung Batu depend on the operator arranging your transfer. Confirming the boat before you land, rather than assuming one will be waiting, avoids the most common cause of an unplanned overnight in Berau.
