Swimming with whale sharks in Saleh Bay is one of the most extraordinary wildlife experiences in Indonesia. Located off the northern coast of Sumbawa, this remote bay is one of the best places to see whale sharks in Indonesia, with reliable encounters year-round.

Unlike many destinations where sightings are seasonal, Saleh Bay offers consistent encounters thanks to traditional fishing platforms that attract these gentle giants. During my own early-morning dive in Saleh Bay, I spent nearly two hours snorkeling with three whale sharks calmly feeding beneath the platform — one of the most peaceful dives I’ve ever experienced in Indonesia.

In this guide, I’ll show you exactly how to swim with whale sharks in Saleh Bay, when to go, and what to expect.

Why Saleh Bay Is Unique for Whale Sharks

Saleh Bay differs from other whale shark destinations for several reasons:

• 🐋 Year-round sightings
• 🌊 Calm, shallow waters
• 🚤 Small local boats (no mass tourism fleets)
• 🌅 Remote, untouched environment
• 🐟 Traditional bagan fishing platforms attracting sharks

Around 120 whale sharks are believed to frequent the area. These giants, which can grow up to 12 meters long, are harmless filter feeders that feed on plankton and small fish.

The interaction feels natural and unforced.

What to Expect on a Whale Shark Tour

Early Morning Departure

The experience starts early.

Boats typically depart around 4:00–5:00 AM from small fishing ports in Saleh Bay. If you are staying in Sumbawa Besar, departure may require leaving around 2:00 AM. Many travelers choose to stay closer to the bay the night before.

The boat ride takes approximately one hour, heading north toward Mount Tambora. On clear mornings, the silhouette of the volcano creates a dramatic backdrop.

Arrival at the Bagan

Around sunrise, the boat reaches a bagan — a traditional Indonesian fishing platform finishing its night catch.

Whale sharks are attracted by small fish and plankton released near these platforms. It usually doesn’t take long before the first massive silhouette appears below the surface.

Often, several whale sharks gather peacefully beneath the platform.
