Black Rock is named after a large, dark rock hidden under 10 feet of water. The sinister rock has been the demise of many ships. You’ll want to hike or bike into this area; it’s not accessible by car. There are a couple of beaches at the base of the bluffs. While certainly not the best place for lying on the beach, sandy stretches can be found here. Stunning scenery. Black Rock is the end point of a few trails through Rodman’s Hollow. Use caution when swimming; the surf can be very rough here.
