Monumento Natural de la Caldera del Rey, Playa de las Américas

The natural monument of the Caldera del Rey constitutes a geomorphological element of great singularity, being one of the three best samples of phreatomagmatic-explosive volcanism in Tenerife. It is a large caldera that was created when the magma came into contact with the water, thus favouring the explosiveness of the eruption due to the release of gases produced. Most of this natural monument is dominated by sálic materials, although in its northernmost area there are ancient basaltic materials that belong to the Adeje Massif. With an extension of 108.7 hectares, it is located in the southern municipality of Adeje.

In spite of the fact that the height it reaches is not very great, the set leaves a magnificent volcanic stamp and is declared on June 19, 1990, like natural place of interest of the Caldera del Rey and reclassified to its present category of natural monument, on December 19, 1994.
