Indonesia is known for its rich marine biodiversity, but if you’re looking for a rare and unforgettable experience, swimming with whale sharks in Sumbawa should be at the top of your travel list. These gentle giants frequent the waters of Saleh Bay, offering visitors the chance to witness the magic of nature up close and personal — far from the crowds of Bali or Komodo.
Whether you’re a seasoned diver, a curious snorkeler, or simply a traveler in search of unique adventures, the whale sharks Sumbawa experience is one you’ll never forget.
Why Sumbawa?
Sumbawa is an island in West Nusa Tenggara, located between Lombok and Flores. While relatively less visited than its neighbors, Sumbawa is fast emerging as a destination for those seeking pristine beaches, raw natural beauty, and authentic cultural experiences. But perhaps its most extraordinary secret lies beneath the surface of the sea — the seasonal presence of whale sharks.
Unlike other whale shark destinations like the Philippines or Mexico, Sumbawa offers a more personal and serene experience, without large crowds or commercialized excursions. The natural beauty of the island adds even more charm to the encounter.
What Makes Whale Sharks in Sumbawa Unique?
Whale sharks (Rhincodon typus) are the largest fish species on Earth. Despite their intimidating size — growing up to 18 meters — they are filter feeders and completely harmless to humans. Swimming beside them is like floating next to a slow-moving submarine with white spots and wide-open jaws gently scooping plankton from the water.
The whale sharks Sumbawa are often found near traditional fishing platforms known as “bagan.” These floating fish traps attract plankton and small fish, which in turn lure the whale sharks close to the surface. Because of this natural attraction, sightings in Saleh Bay are predictable and frequent, especially in the right season.
Best Time to See Whale Sharks in Sumbawa
Although whale sharks may appear year-round, the peak season to see them in Sumbawa is from April to October. During these months, the sea is calmer, making boat trips more comfortable and snorkeling conditions ideal.
Mornings are the best time to embark on a whale shark tour, as the animals are more active and likely to be feeding near the bagan. Tour boats typically leave before sunrise to maximize chances of interaction while minimizing environmental disruption.
How to Reach Sumbawa
Getting to Sumbawa is relatively easy from other parts of Indonesia:
- From Lombok: You can take a fast boat or fly from Lombok International Airport (LOP) to Sultan Muhammad Kaharuddin III Airport in Sumbawa Besar.
- From Bali: Fly to Lombok, then continue to Sumbawa by air or overland via ferry.
- From Jakarta or Surabaya: Direct flights are available to Sumbawa Besar with occasional connections.
Once you’re in Sumbawa, Saleh Bay — the main whale shark location — is about a 1 to 1.5-hour drive from Sumbawa Besar. Most tour operators include hotel pickup and transportation to the departure point.
What to Expect on a Whale Shark Tour
Joining a whale sharks Sumbawa tour is a carefully planned but unforgettable experience. Here’s what a typical trip looks like:
- Early Departure: Most tours begin between 3:30 AM and 5:00 AM to reach the fishing platforms before sunrise.
- Boat Ride: You’ll travel by small boat to the bagan in Saleh Bay, enjoying views of sunrise over the ocean.
- Snorkeling Experience: Once whale sharks are spotted, you’ll be allowed to enter the water under the guidance of certified guides.

Encounters can last from 15 minutes to over an hour, depending on the whale sharks’ behavior and presence. Many guests describe it as a deeply emotional, even spiritual, experience.
Conservation and Responsible Tourism
As interest in whale shark encounters grows, so does the importance of responsible tourism. Whale sharks are a protected species, and efforts are underway to ensure that their interaction with humans remains safe and sustainable.
When choosing a tour operator, look for those who:
- Follow the code of conduct for marine wildlife.
- Limit the number of guests per trip.
