The Green Lagoon is situated close to the fishing village of El Golfo, on the south-western coast of the island. The water in this spectacular semi crater is denser and saltier than that of the Dead Sea. Lago Verde is a former volcanic crater infiltrated by sea water and its green colour is caused by the algae that has taken over the lake. The contrast between the green of the lagoon, the ochre of the volcanic rock and the black of the beach is as striking as it is spectacular. It is possible to walk right up to the edge and fully take in this token of mother nature's beauty! The lake, however, is a protected natural area, meaning it is strictly forbidden to swim in it or even touch it.
