Adventurous and experienced divers should not miss The Cathedral from the itinerary. With seamounts and canyons, the greytip, whitetip, and blacktip reef sharks are often found in this dive site. Not only that, but mobula rays, schools of tunas, mackerels, and barracudas can also be seen moving swiftly in the waters. Sea snakes, sea cucumbers, and different species of soft corals in various colors are abundant here.

With a depth beyond 50 meters, The Cathedral has more swell and currents than any other dive site. At around 40 meters, an enormous cave appears, ready to be explored.
