Boat access only. Enter Mackeral Cove, Jamestown, RI from the south via Rhode Island Sound - just north of Kettle Bottom Rock (another good dive site w/wreck remains). Boats under 30-32 feet may drop anchor inside the first small cove on the eastern shoire of mackeral Cove. Larger boats need to drop anchor just outside this small cove off Horsehead. Gear up, descend and follow the perimeter reef - heading southeast.
Descend gradually to depths as deep as 60 feet - as you follow the western reef perimeter, depth increases beginning with scattered large rooks with many lobster crevices and anenomes. Gradually swim deeper into large shelf overhangs and shallow caves. There are many areas to explore, but watch your air for the possible against current swim back to the boat. It's best to dive during slack tide and wait for a northern wind direction prior to diving for best visibility.
