Mainit Bubbles Point is a boat-access Anilao dive built around bubbling volcanic sand, a long reef, and a deeper wall that make it popular with photographers. The site is usually planned as a guided boat trip, with the shallow bubble area and light current keeping it approachable for many divers. Marine life ranges from macro subjects to turtles, stingrays, and reef fish, while the deeper wall adds a little more structure for the second half of the dive. Dry-season conditions are usually the most reliable.
