About this site
Romblon is an island province in the Sibuyan Sea, part of the Luzon island group in the Philippines, known for its marble industry and surrounding smaller islands. The Giant Clam Sanctuary sits in the waters near Romblon town, reached by a short boat trip from the harbor area, and is a reef dive suited to beginners with a maximum depth of about 13.5 metres. Divers have reported pipefish and seahorses on the reef, along with giant clams that can snap shut and are worth keeping fingers clear of.
