Nice, secluded dive site. A pretty drive down Marrowstone Island. The park offers other things to do for your non-diving friends and partners. The pilings (0-40ft) are loaded with life, great for photographers. Beyond the pilings (>30-40ft) are fields of sea pens, concrete hidey-holes for fish and critters, and a hard sandy bottom sloping gently down. *Very current dependent, as it is exposed to the sound.* During a good slack tide the pilings would make a good dive for beginners or a navigation class. Farther out is good for intermediate divers seeking more variety.
