Located along the Mendocino coast of California, USA, Bowling Ball Beach is located about three miles south of Point Arena, where Schooner Gulch Road intersects State Highway 1. Until recently there were two trailheads from this location. The Southern trail still leads visitors to Schooner Gulch Beach. However, the northern trail, which was recently closed due to erosion used to lead you to the fascinating place you see below, Bowling Ball Beach.
The unique stone orbs that give this beach its name are quite visible during low tide (high tide not so much) and are known to geologists as concretions. Concretions are hard bodies that for a variety of reasons can form in sediment before they become sedimentary rocks
