The Punta Sur National Park, an island protected area that covers the beaches, lagoons, the low jungle, the mangroves and the coral reef that surrounds the place. It has an approximate dimension of 1 km. The Celarain Lighthouse is located on the extreme headland of the Punta and in the building built to provide services to the lighthouse is a nautical museum that offers information on the history of the place.
To the northwest of the lighthouse is the so-called Tomb of the Caracol, an archaeological vestige dedicated to Ixchel, deity of the Mayan culture. This structure, built by the Maya in the postclassic period, is equipped with a dome that in turn was covered with marine snails that produced a buzz with strong winds. The whole functioned as a kind of alarm, warning about the intensity of winds on the island.
