Dive-site story
Located along the eastern coast of Siquijor Island, Olang Marine Sanctuary features a protected reef system that steps down from shallow seagrass flats into a coral slope. Divers drift along dense clusters of branching stony corals and sea fans, scouring sandy gullies for macro critters while open-water fish patrol just off the reef edge.
Extensive colonies of hard corals sheltering macro life in the shallows
Regular encounters with green sea turtles grazing along reef edges
Sheltered marine sanctuary conditions with high fish biodiversity
