Cabildo de Tenerife

La Caldera del Rey


What is it?

Caldera del Rey is a particularly unique geomorphological structure, as it is one of the three best examples of phreatomagmatic volcanism (when magma comes into contact with water) in Tenerife. However, the area’s plant life is in a serious state of deterioration, owing to the agricultural activity further inland: only on the inner slope to the north of the caldera will you find well-preserved escarpments that are home to certain rock-growing plants, which thrive on rocks despite the almost total absence of soil.

Getting there

Caldera del Rey can be accessed from the TF-1 via the exit for San Eugenio en Las Américas. The exit takes you on to the road leading up to San Eugenio Alto; after travelling for a kilometre, you will arrive at the Natural Monument.

Total area

180,7 ha.



Governing legislation

Caldera del Rey was declared a Natural Monument and area of environmental sensitivity by Autonomous Region Act 12/94, which was later integrated into the Organisation of the Canary Islands Territory Act via Legislative Decree 1/2000.
