This Aug. 1, 2018, aerial photo made available by the Florida Department of Environmental Protection shows Grayton Beach State Park in Santa Rosa Beach, Fla. The beach earned the first spot of top U.S beaches according to Florida International University professor Stephen Leatherman. The beach was chosen in part because of its sugar-white sand and its clear, emerald-green water. (Running Man Pictures/Courtesy of Florida Department of Environmental Protection via AP)
