Indonesia is one of the very few countries on Earth where you can swim with whale sharks in more than one region — and the options could hardly be more different. Some spots are a short drive from a city; others need a week on a liveaboard. Some deliver sightings almost daily; others depend on season and luck.
Most articles simply list the locations. This guide compares them — access, best months, reliability, and rough budget — so you can pick the right one for your route. Full disclosure: we are a local operator running daily trips in Saleh Bay, Sumbawa, so that section is written from first-hand experience. We’ve kept the comparison honest.
1. Saleh Bay, Sumbawa — the Year-Round Favorite
Saleh Bay is the largest bay on Sumbawa Island, and it works differently from almost every other whale shark destination in the world. Hundreds of traditional bagan fishing platforms operate across the bay at night, and when fishermen lift their nets before dawn, escaping plankton draws whale sharks in to feed. Because the bagans work most of the year, the whale sharks stay most of the year — this is not a migration stop.
On our own trips, more than 95% of guests end up swimming with at least one whale shark. April to November is the sweet spot (calm seas, clear water), while January to March is rougher and less predictable. Day trips start from around IDR 540,000 per person, and you can join from Lombok or from Sumbawa Besar — see the full options on our Sumbawa whale shark tour page.
Best for: travelers already in Bali, Lombok, or Sumbawa who want the highest chance of an encounter without an expedition budget.
2. Botubarani, Gorontalo — Shore Access in Sulawesi
Botubarani village, a short drive from Gorontalo city in northern Sulawesi, became famous because whale sharks appear remarkably close to shore — sometimes just tens of meters from the beach, in water shallow enough for a small canoe ride out. It is one of the cheapest and easiest whale shark encounters in Indonesia when the animals are around.
The catch is that word: when. Sightings in Botubarani famously come and go — the sharks can be present daily for weeks, then disappear for weeks or months. If you are in Sulawesi anyway, ask locally about recent sightings before making the trip.
Best for: travelers already exploring Sulawesi who are flexible about timing.
3. Talisayan, Berau — Bagan Sightings Near Derawan
On the east coast of Kalimantan, the fishing town of Talisayan offers early-morning whale shark encounters around bagan platforms — the same fishermen-and-plankton dynamic as Saleh Bay, on a smaller scale. Most travelers combine it with the Derawan archipelago (Maratua, Kakaban and its famous stingless-jellyfish lake), which is one of Indonesia’s best island-hopping circuits.
Getting there takes commitment: fly to Berau, then drive roughly three hours to Talisayan, with boat charters arranged locally. Calm-season mornings give the best odds.
Best for: divers and island-hoppers building a Derawan itinerary.
4. Cenderawasih Bay, West Papua — the Legendary Expedition
Cenderawasih Bay National Park is Indonesia’s most famous whale shark destination among divers worldwide. Around the fishing platforms near Kwatisore, whale sharks have learned to visit the nets — often hanging almost vertically beneath the bagans — and encounters are considered reliable across much of the year.
The experience is extraordinary, and so is the logistics: this is remote Papua, reached in practice by liveaboard, typically from Nabire or Manokwari. Expect a multi-day trip with a budget in the thousands of dollars rather than hundreds of thousands of rupiah.
Best for: divers on a bucket-list expedition with time and budget to match.
5. Bentar Beach, Probolinggo — Java’s Seasonal Visitors
Every year, roughly between December and April, whale sharks pass along the north coast of East Java near Probolinggo, and local boats run short trips from Bentar Beach when the animals are spotted. It is the closest option to Surabaya, but sightings vary a lot from year to year, and conditions are more about viewing from the boat than long swims in clear water.
Best for: Java-based travelers who want a low-cost look during the season.
6. Quick Comparison
| Location | Getting there | Best months | Reliability | Rough budget |
|---|---|---|---|---|
| Saleh Bay, Sumbawa | Fly to Lombok or Sumbawa Besar; tours from Labuan Jambu | Apr–Nov (possible year-round) | Very high — 95%+ on our trips | Day trips from IDR 540K |
| Botubarani, Gorontalo | Short drive from Gorontalo city | Unpredictable | Medium — sharks come and go | Very low |
| Talisayan, Berau | Fly to Berau + ~3 hr drive | Calm season mornings | High when bagans are active | Mid — usually part of a Derawan trip |
| Cenderawasih Bay, Papua | Liveaboard via Nabire/Manokwari | Much of the year | Very high | High — multi-day liveaboard |
| Bentar, Probolinggo | ~2–3 hr drive from Surabaya | ~Dec–Apr | Low–medium | Low |
7. Which One Should You Choose?
If you are routing through Bali, Lombok, or anywhere in Nusa Tenggara, Saleh Bay is the practical winner: the highest reliability outside Papua, day-trip logistics, and a fraction of an expedition budget. Solo travellers can keep costs down with the shared open trip from Labuan Jambu (from IDR 650K), or save time with the speed boat day tour. Already in Sulawesi? Check recent Botubarani sightings. Building a diving itinerary? Talisayan slots neatly into Derawan, and Cenderawasih Bay is the once-in-a-lifetime version. In Java between December and April, Bentar is worth a morning.
8. Swim Responsibly, Wherever You Go
Whale sharks are listed as endangered on the IUCN Red List, and the rules are the same at every location: no touching, keep a few meters of distance, no flash photography, and let the animal set the pace. Choose operators who brief you before you enter the water and limit how many swimmers go in at once — wherever in Indonesia you end up meeting one. Curious how this actually plays out at the bagan platforms of Saleh Bay — and whether the sharks there are fed? Read our full essay on the ethics of Saleh Bay.
