The prevailing southeast swells make this a tricky dive, but when seas are calm this site is magical. So much so that it has hosted several underwater weddings. Located on St. John's east end between Ram Head and Leduck Island, arches, tunnels and caves are its signature features. The cave, known as â€œThe Cathedralâ€ , is encrusted with vivid sponges and orange cup coral. Schools of black durgeons, porkfish and silversides populate the shoal. Northeast of the cave is a series of deep walls and tiers that shelter spotted drums and Queen and French Angelfish.
