La Romana, Dominican Republic
Private to the resort, Minitas Beach is immaculate — there was not a single piece of garbage to be found anywhere. The sand is soft, and a man-made reef several hundred feet out keeps the water especially calm and safe for young children. Even better, lifeguards are on duty from 9 a.m. to 6 p.m. daily. In addition to the immaculate beach, Casa de Campo’s 7,000-acre property comes with three world-class golf courses, an on-site horse stable, a luxurious spa, 20 restaurants, and even a replica of a 16th-century Mediterranean villa.
