Tucked between the volcanic ridges and quiet coastlines of Sumbawa Island in Indonesia lies a pristine marine wonder: the whale sharks of Saleh Bay. While the region remains relatively under the radar compared to global hotspots like Mexico’s Isla Holbox or the Philippines’ Donsol, Saleh Bay is quickly gaining attention from responsible travelers and marine enthusiasts around the world.
Why? Because the whale sharks of Saleh Bay offer an unmatched opportunity for ethical, natural encounters that are deeply respectful of the ocean’s rhythms. This isn’t a tourist circus — it’s a quiet, awe-inspiring experience in one of Indonesia’s most breathtaking marine environments.
In this article, we’ll take you through everything you need to know about the whale sharks of Saleh Bay — from what makes them special, when to visit, how to interact responsibly, and why this hidden gem might just be the best-kept secret in Southeast Asian marine tourism.
Meet the Whale Sharks of Saleh Bay
Whale sharks (Rhincodon typus) are the gentle giants of the ocean. As the largest fish in the sea, they can grow up to 12 meters (40 feet) long and weigh more than 20 tons. Despite their size, they pose no threat to humans — these filter feeders consume only plankton, krill, and small fish.
Saleh Bay, located in the northern part of Sumbawa Island, has become a consistent feeding ground for these majestic animals, thanks to its nutrient-rich waters and unique fishing traditions.
The whale sharks of Saleh Bay are particularly known for:
- Their calm and curious behavior
- Consistent seasonal appearances
- Close interaction with traditional bagan fishing platforms
- Natural feeding patterns without human interference
Unlike other regions where whale sharks are lured with bait or artificial feeding, Saleh Bay provides an organic, authentic setting that makes each encounter truly special.
Why Are Whale Sharks Attracted to Saleh Bay?
One of the main reasons why whale sharks gather in Saleh Bay is the presence of traditional Indonesian fishing platforms called bagan. These floating wooden structures are used by local fishermen to attract and catch small fish using underwater lights at night.
In the early morning, whale sharks come to these platforms to feed on the small fish and plankton that congregate there. This natural behavior creates predictable, low-impact opportunities for sightings and snorkeling.
What makes the whale sharks of Saleh Bay unique is that they are not conditioned by feeding or artificial tourism tactics. Their visits are a direct result of local fishing practices, which makes this one of the most ethically sound destinations for whale shark tourism in the world.
When to Visit: Best Time to See Whale Sharks of Saleh Bay
The best time to visit Saleh Bay for whale shark encounters is between May and October. During these months, plankton blooms are more frequent, and water conditions are calm — creating the perfect environment for whale shark sightings.
Here’s a quick overview:
- Peak Season: June to August
- Water Visibility: Often excellent in dry season
- Sighting Frequency: High — sightings are considered very reliable
Tours usually start very early in the morning (around 5–6 AM) to align with whale sharks’ feeding schedules near the bagan.

If you’re lucky enough to plan a trip to Saleh Bay, here’s what a typical tour might look like:
🛥️ Departure Before Dawn
Most tours depart from the towns of Kempo, Dompu, or Sumbawa Besar. The boat ride through the calm bay waters at sunrise is a peaceful and scenic experience in itself.
🐋 Sighting the Whale Sharks
As your boat approaches a group of bagan, local fishermen help spot the whale sharks. It’s common to see one or more of these massive animals gliding gracefully near the platforms.
🤿 Snorkeling Session
Once it’s safe, guides allow small groups to enter the water for a snorkeling session. The experience of floating beside a creature that dwarfs you — yet poses no threat — is one of awe and humility.
📷 Capture the Moment — Respectfully
Many visitors bring GoPros or underwater cameras to document their encounters. Ethical operators will remind guests to avoid flash, touching, or crowding the animals.
