South of the former fishing village of El Golfo is one of the most famous sights of the island of Lanzarote. It is the partially sunken in the sea crater of the volcano Montaña de Golfo, which has formed a lagoon, which is located about 50 meters from the coast. The distinctive green color of the lagoon caused by unicellular algae that have adapted to the high salinity of the lake. By subterranean connections to the sea Sea water flows into the lagoon and ensures permanent bonding. This balance of nature is disturbed, for unknown reasons in recent years. The now cordoned green lagoon evaporates more and more and now has only a fraction of their original size.
The name of the crater lake, Charco de los Clicos, comes from a kind of edible seafood, the Clicos, which occurred frequently in this place earlier.
