Introduction: Nature’s Hidden Masterpiece
When most travelers think of Indonesia, images of Bali’s surf beaches or Komodo’s dragons usually come to mind. But venture a little further east, and you’ll uncover a lesser-known paradise that offers something truly unforgettable—whale sharks in Sumbawa.
This quiet, off-the-beaten-path island is home to one of the most magical marine experiences in Southeast Asia: swimming side-by-side with the largest fish in the ocean. Unlike the crowded tourist hotspots elsewhere, Sumbawa offers a raw, authentic, and deeply moving connection with nature.
What Makes Sumbawa So Special?
Sumbawa lies between Lombok and Flores, forming part of Indonesia’s West Nusa Tenggara province. With rugged landscapes, quiet beaches, and minimal commercial development, Sumbawa feels like a world untouched by time.
But beyond its scenic landscapes and cultural richness, one of Sumbawa’s biggest treasures lives beneath the waves—the magnificent whale sharks that roam the waters around Saleh Bay, particularly near Labuhan Jambu.
What sets whale sharks Sumbawa apart from other destinations like the Philippines or Mexico is the consistency and accessibility of the sightings, as well as the unique human-nature interaction that has developed over the years.
The Whale Sharks of Saleh Bay
Saleh Bay, a large semi-enclosed body of water on the northern coast of Sumbawa, has become one of the top spots to witness whale sharks in Indonesia. Local fishermen in the bay use traditional floating fishing platforms known as bagan to catch small fish such as anchovies and krill.
Interestingly, the whale sharks have learned to follow these bagan, feeding on the fish that escape from the nets. This remarkable behavior has created a consistent opportunity for travelers and researchers to encounter these gentle giants almost daily during peak months.
The whale sharks in Sumbawa are generally curious but calm, and swimming beside them—watching their massive bodies move effortlessly through the water—is a deeply humbling experience.
What Is It Like to Swim with Whale Sharks?
Imagine the early morning sun rising over the calm sea. You’re on a small local boat, gently gliding over glassy water. Suddenly, the boat slows down, and the guide points excitedly over the side.
As you slip into the warm, turquoise sea with your snorkel mask on, a dark shape looms in the distance. Slowly, it becomes clear: a whale shark, easily the size of a small bus, is moving peacefully below you. You hear nothing but your own breath and the rhythm of the ocean as you swim beside one of nature’s most magnificent creatures.
Unlike diving, you don’t need special certifications to enjoy this experience. Most tours provide basic gear and guidance, making it accessible to beginner swimmers and nature lovers alike.
When Is the Best Time to See Whale Sharks in Sumbawa?
Although whale sharks can be seen year-round, the best time to visit is during the dry season, between May and October. During these months, weather conditions are more favorable, the sea is calmer, and visibility is excellent—making it ideal for snorkeling or free diving.
Many whale shark tours depart from Labuhan Jambu, a small coastal village that has developed into a hub for eco-tourism thanks to the growing interest in whale shark encounters.
Ethical Guidelines for Whale Shark Encounters
As this incredible tourism activity grows in popularity, it’s essential to keep sustainability at the core. Here are some important ethical guidelines to follow when visiting whale sharks Sumbawa:

Many former fishermen now work as tour guides, boat captains, or marine spotters, creating sustainable income alternatives that reduce overfishing and protect marine biodiversity.
Additionally, a portion of the tour fees often goes into marine conservation efforts, helping to monitor whale shark populations and educate future generations about protecting the ocean.
