Dive-site story
Located off the coast of Siargao Island, Blue Cathedral ranks among the premier cavern dives in the Philippines. The site features a massive underwater chamber flanked by archways that allow shafts of sunlight to pierce through the blue water, illuminating sprawling sea fans and sponges. Outside the cavern entrance, the reef drops into an oceanic drop-off facing the open Pacific, where pelagic fish gather in the prevailing currents.

Seasonality
Spring and summer offer the calmest sea conditions before heavy Pacific surf swells build later in the year.
