Siquijor Sunken Island

Siquijor Sunken Island is a submerged seamount located off the coast of Siquijor, the mystical island in the central Visayas that remains one of the Philippines' best-kept diving secrets. Rising from considerable depth, the top of the seamount sits at around 8 meters, creating a plateau of pristine coral that slopes away into the blue on all sides. The isolation of this site means it receives very few divers, and the reef health reflects this — dense thickets of staghorn and table coral blanket the summit, alive with clouds of orange and purple anthias. The open-water position of the sunken island makes it a magnet for pelagic species. Whitetip reef sharks rest on the sandy patches between coral heads, while giant trevally and barracuda patrol the edges of the plateau. Eagle rays are spotted gliding past during the cooler months, and green sea turtles are regular visitors. The visibility at this site is often exceptional, frequently exceeding 30 meters, which provides dramatic wide-angle photography opportunities with the seamount silhouetted against the deep blue. Moderate currents are typical at the site, which is why it is recommended for intermediate divers with experience in current diving. Dive operators from Siquijor town run trips to the seamount when conditions allow, typically during the calm dry season months from November through May. The combination of pristine coral, pelagic encounters, and the sheer remoteness of the location makes Siquijor Sunken Island a genuinely unspoiled diving experience that rewards those willing to venture off the beaten path.
