This is an ancient volcanic dome which covers 169.7 hectares and rises between the two ravines of Guaria and Cuéscaro. It provides refuge for many endangered species such as the Balillo or the Corriguela.

This volcanic monument is 1,055 metres high and has been used for agricultural purposes by recent human inhabitants. Today it is a protected area because of its many endangered inhabitants. It also holds great historical value due to the fact that the original Guanche inhabitants of Tenerife regarded it as a sacred place and performed many religious customs here.
