Sunken Island, Pamilacan is an offshore sunken seamount between Alona Beach and Pamilacan Island. It is best known for a current-swept profile, a shallow top that drops into a steeper slope, and a mixed coral-and-rock landscape where fish and small critters hide. Plan it as a boat dive that depends on a workable current window, not a relaxed reef hop.

Community notes to help plan your visit.
Scuba Diving
Depth range runs from about 10 m down to 30 m along the slope.
Freediving
Not a freedive-first site; the current and depth make it a scuba drift dive.
Snorkeling
Snorkeling is not the focus here; the site is built for divers who can handle current and drift.
