On the central coast north of Valparaíso, the beach resort town of Concón is popular with Chileans for its boardwalk, great restaurants, and, most of all, the 52 protected acres of monumental sand dunes that cascade down from high bluffs all the way to the sea. In addition to hikers, the dunes draw sandboarders who climb to the top, wax their rented boards by rubbing them with candle stubs, and then slide or sled down the slopes to the sound of the sea lions barking in the waters below.
