Diving in Bicol is best known for whale sharks, but it offers far more than just big encounters. The region is rich in both pelagic species and macro life, set against colorful coral reefs and dramatic underwater terrain. The four main dive areas in Bicol include Donsol, Ticao Island, Catanduanes, and Calaguas. Donsol diving is famous for seasonal whale shark sightings from November to May, while Ticao Island attracts manta rays to its cleaning stations. San Miguel Island, nearby, boasts some of the most vibrant reefscapes in the Philippines. In Catanduanes, diving is still developing, giving adventurous divers the chance to explore untouched sites.
The best time to dive in Bicol is from November to May, when whale sharks gather in Donsol and visibility is at its best. These months offer calm waters and ideal weather across top dive sites like Ticao Island, San Miguel Island, and Catanduanes. June to October marks the rainy season - diving is still possible but with rougher seas and lower visibility. For vibrant reefs, pelagic action, and easier travel conditions, plan your Bicol diving adventure during the dry season.
