Leave in the dark
The early run starts before sunrise so you reach the platforms as the sky lightens.
Destinations · Talisayan
A pre-dawn snorkel beside the lift-net fishing platforms off Talisayan, Berau, where whale sharks feed at first light. Included on our 4D3N Derawan trip.
The encounter
Local fishermen work wooden bagan lift-net platforms through the night, drawing baitfish with lamps and hauling the nets at first light. Whale sharks learned to link the platforms with an easy meal and arrive to feed at the surface while the crew is still working.
Whale sharks are filter feeders with no interest in people, and they move slowly enough that a snorkeller can hold position beside one. Most seen here are juveniles of four to eight metres; the species grows beyond twelve.
No diving certification is needed. Confident swimming in open water with a mask and snorkel is the real requirement. Fins are not included in our trips, so bring your own.

The morning
The timing dictates the whole day. There is no afternoon version of this activity.
Trip length
Every trip meets at Kalimarau Airport (BEJ) in Berau: about 2.5 to 3 hours by road to Tanjung Batu, then about 40 minutes by speedboat to Derawan.
| Trip | Whale sharks | What else it covers |
|---|---|---|
| 4D3N | Included, on day three | Day two: Maratua, Kakaban, Sangalaki. Day three: Talisayan, Manimbora, Labuan Cermin |
| 3D2N | Not included | Day two: Maratua, Kakaban, Sangalaki |
If the whale sharks are your priority, choose the 4D3N: private, or the open trip at USD 280 per person.
When to go
The best season is April to November, set by sea state rather than by the sharks. July to September is the calmest and driest stretch, with the most reliable pre-dawn crossings; April to June has fewer visitors on the platforms; October and November can bring squalls. December to March is the wetter period, though open-trip departures still run.
Whale sharks are wild and no operator can guarantee them. Sightings are frequent enough that the stop is a fixture, but a blank morning is possible. Book two to three months ahead for July to September.

Swim responsibly
The fishermen are the reason the sharks are there at all, and behaviour in the water decides whether the encounter lasts.
The wider route
Talisayan is the mainland-coast stop; the rest of the route is offshore or on the same day-three run.

Answers
Between 04:00 and 05:00, because the whale sharks feed at the bagan platforms while the fishermen haul their nets at first light. You are usually in the water from around sunrise for 60 to 90 minutes. There is no afternoon departure.
