With a number of jetties and varied coastline, Folly Beach has a number of different spots. All of Folly is lined with jetties. They've done a questionable job of protecting the beach, but they've produced lots of different peaks. The best spot at Folly is called the Washout. It's a long stretch of jettied beachbreak that can break with a tremendous amount of power on northeasterly swells or on hurricane swells. Beware of jetty rocks, underwater debris and current on larger swells. Take Highway 17 south of Charleston, then take Highway 171 to McKevlin's surf shop. Buy wax, head East onto East Ashley. Park along the beach.
