Why dive here
With 35+ marine species recorded in the area - including nurse sharks - Cathedral Rocks offers some of New England's richest diving.
Cathedral Rocks offers a rugged New England dive, best suited for those comfortable with chilly water and rocky topography. Below the surface, you’ll navigate large boulders and ledges, with plenty of nooks to poke around in. Expect to spot lobsters, crabs, and a variety of cold-water fish hugging the substrate. It's a solid choice for a local boat dive when conditions are calm.
