El Caletón is a swimming area, formed by several pools of natural origin, located in the municipality of Garachico on the Spanish island of Tenerife. Next to the swimming pools is the Castle of San Miguel.
The pools were originated by the lava coming from the eruption of the Trevejo volcano in 1706. When coming into contact with the sea water, the lava solidified, giving rise to capricious and beautiful forms.
