Sandugan Wall

Larena · Siquijor · Philippines

Sandugan Wall is the premier dive site on Siquijor, the enchanting island that Filipinos have long called the mystical island of the Visayas. Located within the Sandugan Marine Sanctuary near the port town of Larena on Siquijor's northeast coast, this protected wall dive offers a vertical underwater landscape that is both dramatic in scale and exceptionally rich in marine life. The wall begins at a mere 5 meters below the surface and drops steeply, in some sections nearly vertically, to 45 meters where the slope begins to level out. The upper wall from 5 to 15 meters is carpeted with healthy hard corals in remarkable variety, including branching, plate, and massive formations that benefit from the sanctuary's protected status. Gorgonian fans begin to appear at mid-depths, growing larger and more numerous as the wall deepens, while soft corals and sponges add splashes of color to overhangs and crevices throughout the vertical profile. Sea turtles are the wall's signature residents. Green and hawksbill turtles rest on coral ledges at various depths, feed on sponges along the wall face, and show impressive tolerance for divers, creating intimate encounters that photographers treasure. Whitetip and blacktip reef sharks patrol the deeper sections, while schools of jacks and barracuda swirl along the wall edge. The sanctuary's macro life is equally rewarding, with frogfish, nudibranchs, scorpionfish, and lionfish hiding in plain sight among the coral architecture. Visibility at Sandugan is one of its greatest assets, frequently exceeding 25 meters during the dry season from November to May when water clarity reaches its peak and temperatures hold between 27 and 30 degrees Celsius. Currents are generally mild, making the wall accessible to divers from Open Water certification upward, though the deeper sections beyond 30 meters are reserved for advanced divers. For those exploring the central Visayas dive circuit, Sandugan Wall offers a quieter, less commercial alternative to the region's more famous sites, with underwater quality that stands comparison with the best wall dives in the Philippines.
