6 Ethical Places to Swim with Whale Sharks

Whale sharks, the gentle giants of the ocean, are truly remarkable creatures. As the largest fish in the sea, they can grow up to 40 feet long and weigh as much as 20 tons. Despite their size, whale sharks are filter feeders, primarily consuming tiny plankton, which they scoop up with their wide mouths. They can dive to depths of over 6,500 feet and can often be seen migrating thousands of miles across the globe. Swimming alongside a whale shark is not just an unforgettable experience; it offers a unique opportunity to connect with these beings in their natural habitat.

However, not all whale shark encounters are created equal. It’s crucial to choose ethical locations that prioritize conservation and the well-being of these gentle giants. For example, swimming with whale sharks in Cebu, Philippines, may seem appealing, but this location has been criticized for its mass commercialization and unethical practices. In Cebu, whale sharks are baited to come close to shore, which alters their natural behavior and leads to encounters in a small lagoon contaminated with motorboat oil. Instead of a wild and immersive experience, swimmers are often in an outdoor zoo-like setting, waiting their turn to jump in for a quick photo opportunity. This type of experience guarantees a sighting but sacrifices the true essence of swimming with these magnificent creatures.

To ensure a meaningful and respectful interaction with whale sharks, consider these ethical destinations that emphasize sustainability and marine conservation.
