Marcos Cave - Anilao
Marcos Cave offers a straightforward cavern dive, more an overhang than a true cave. You’ll find a decent school of glassfish inside, often a moray eel tucked into the back, and the exit light is always visible. It’s a good spot for newer divers wanting a taste of overhead environments without the commitment of deeper penetration. Visibility is typically good here, making navigation easy.
