About Cathedral Rocks
Cathedral Rocks is a Rockport shore dive on a rugged granite wall. The site drops quickly from the entry rocks into a dramatic ledge system with boulders, cracks, and chasms, so the dive is all about timing the entry and exit, handling cold-water conditions, and working the shoreline when wind and tide are right. Fish and invertebrate life cover the rocks, and the site rewards experienced divers who can manage a steep rocky approach and a classic New England wall profile.
