Mackerel are also common. In the shallower water here anemones, always with their resident clownfish, are abundant. While these caves and adjoining walls are interesting in themselves, the recommended procedure is to sit inside the cave, relax and wait for big fish to pass by. Note that the shallowness of the reef at this site can make diving from a boat very tricky at low tide, especially if there's are prevailing northeasterly winds. Chartered dive boats running from Mactan Island on Cebu down Balicasag often include a stopover at Cabilao Island on their itinerary.
Sightings are common shortly after sunrise or just before sunset.
The best dive is on the edge of a sand-flat which projects westward from the point at the northwest tip of the island. In addition to the sharks, you may see large barracudas and game fish. Colonies of garden eels live in the sand-flat. When they poke their heads out of their holes to feed, their upper bodies sway in the current like a living carpet of long grass. As you approach they'll withdraw quickly into the sand.
