Celestún is a town in Yucatán, Mexico. It is locate in the northwest corner of the state, just north of the border with the state of Campeche, on the Gulf of Mexico coast at 20°51.5′N, 90°24′W. In 2000 it had a population of just under 6,000 people; however, the population swells to 10,000 during the octopus hunting season. It is mostly a fishing town, with an old 19th century lighthouse (as well as a more modern one) and an abandoned historic Hacienda. Besides fishing, Celestún also produces salt, as it has done from pre-Columbian times. Tourism is also making up an increasing portion of the town's economy, as the community boasts many kilometers of sand beaches and abundant wildlife.
