The cave sections involve an overhead environment, so even though this site suits open water divers, bring a dive torch and stay within natural light range of the exit if you have not done overhead training. Check locally for boat charter options and current conditions before you go, as stronger currents can catch newcomers off guard.
Boat access only. Enter Mackerel Cove, Jamestown, RI from the south via Rhode Island Sound. Boats under 30-32 feet may anchor inside the first small cove on the eastern shore; larger boats should anchor just outside this cove off Horsehead.
