Indonesia is no stranger to breathtaking underwater experiences, but one destination is rising fast in the global spotlight for something truly unforgettable: swimming with whale sharks. While places like Cenderawasih Bay and Gorontalo have drawn attention in the past, a new location is captivating the hearts of adventurous travelers — Sumbawa.
Located between the better-known islands of Lombok and Flores, Sumbawa offers an off-the-beaten-path adventure where travelers can swim alongside the world’s largest fish. In this article, we explore everything you need to know about the whale sharks Sumbawa phenomenon — from when to go, where to stay, how to swim ethically with these giants, and why this destination deserves a place on your bucket list.
Why Whale Sharks Sumbawa is a Hidden Gem
Unlike more commercial whale shark destinations around the world, Sumbawa remains relatively untouched. This makes encounters here feel far more authentic and exclusive. The best part? You’re not just seeing whale sharks from a distance — you’re often swimming right beside them in crystal-clear waters.
Saleh Bay, in particular, has emerged as the hotspot for whale sharks Sumbawa. This massive bay on the northern coast of Sumbawa has nutrient-rich waters that attract whale sharks regularly. The sharks gather here to feed on small fish and plankton, especially during peak season from April to October.
What Makes Sumbawa So Special?
One of the most unique aspects of the whale sharks Sumbawa experience is the interaction between local fishermen and the sharks. Fishermen in traditional boats (called “bagan”) use lights at night to attract fish, which also ends up attracting whale sharks to the surface. These animals have learned to visit these fishing platforms in the early morning to feed on the leftovers, creating a rare and close encounter opportunity for snorkelers.
Unlike other places, the encounters in Sumbawa feel personal. There are fewer tourists, no aggressive crowds, and a real connection to local culture and traditions.
How to Experience Whale Sharks Sumbawa
Most tours depart early in the morning, often around sunrise. Visitors board a boat that travels out to the fishing platforms in Saleh Bay. Once whale sharks are spotted, guests are allowed to snorkel in small groups to observe the animals.
What makes whale sharks Sumbawa tours particularly exciting is that you’re often swimming with multiple whale sharks at a time. It’s not uncommon to see three, five, or even seven of them gliding beneath you. Their gentle movements and calm demeanor make them incredibly approachable — but always from a respectful distance.
If you’re a certified diver, some tours offer scuba diving options, although most encounters happen near the surface, making snorkeling the more sustainable and eco-friendly choice.
Ethical Guidelines for Swimming with Whale Sharks
It’s crucial to follow ethical tourism practices when engaging in any wildlife interaction. The whale sharks Sumbawa experience is only sustainable if tourists and operators protect the well-being of the animals. Here are some guidelines:
- Do not touch the whale sharks. Their skin is sensitive and touching them can cause harm.
- Keep a safe distance. Avoid swimming directly in front of the shark or obstructing its path.
- No flash photography. Bright lights can disturb the animals.
- Limit group size. Choose tour operators that prioritize small group interactions.
- Avoid sudden movements or loud noises. Whale sharks are gentle, but they can be startled.
Ethical behavior helps ensure that future generations will also get to experience the magic of whale sharks Sumbawa.
