Oslob - Dumaguete

Oslob, off the coast of Dumaguete, is all about the whale sharks. And yes, it’s a big deal. We’ve found you’re almost guaranteed an encounter with these gentle giants here, often right at the surface, just 50 meters from shore where the reef drops off steeply. It’s a popular spot, no doubt, but for good reason – seeing a whale shark up close is always special, and Oslob makes it incredibly accessible. While February to April are often cited as prime months, we’ve found decent sightings year-round. It’s a site best suited for snorkelers or divers comfortable sharing the water with a crowd, all focused on the big fish.
