Scuba diving in Sumilon

The marine sanctuary, located on one side of the island, is the first fish sanctuary that was opened in the Philippines, which was initiated in 1974 by Silliman University.

The sanctuary has beautiful coral garden scenery and caverns to explore. The reserve was recognized to be one of the places with the most fish in the Philippines. Both reef fish and sharks are frequent visitors to this dive site. Sumilon Island constantly has currents, so it can only be recommended for experienced divers.
