This is a site of interest where the intention is to protect the traditional activity of naturally obtaining salt.

Prior to the eruptions of 1730/1736 it was home to the largest natural port in Lanzarote, and to a large piece of land used to cultivate wheat, rye, sweetcorn and barley. However, the eruptions created a sand barrier which formed an internal salt water lake called Caleta de Janubio. This began to form salt marshes in 1895 and these were fully formed by 1945.

The Salt Marshes are in the Municipality of Yaiza, on the road that goes to the southerly town of El Golfo, and they are currently being operated by a family business which has been producing salt in a completely natural and ecological way for more than 50 years.
