Protected Samboan reef with sharks, turtles, and coral.
Colase Marine Sanctuary in Samboan, Cebu is a protected shoreline reef with a shallow sandy flat, algae and seagrass beds, and a narrow coral crest that builds into richer reef structure seaward. It is known for strong coral cover, high fish diversity, regular sightings of blacktip reef sharks, turtles, barracuda, and dense reef fish, and it suits wide-angle photography plus snorkeling and relaxed scuba on calm windows.
