Araya has a natural lagoon that produces acantaro salt called Laguna Madre.
Alejandro De Humboldt said in his work Journey to the Equatorial Regions of the New Continent: "It is a wonder that a saltworks that had previously excited the competition of the English, the Dutch and other maritime powers, has not led to the establishment of a village or a farm . There are hardly any poor huts of Indian fishermen at the end of Araya Point. "
Araya has a natural lagoon that produces salt water called Laguna Madre, also with several artificial lagoons that the salt industry built to increase salt production. The salinas have a characteristic purple color that is tinted according to the angle of the sun, the depth and thickness of the salt panels. To accelerate the process and increase salt production, the company floods the lagoons with seawater and let it evaporate until the salt can be collected.
Also has a spectacular beach at the foot of the castle.
