La Fortaleza (2,190 m. altitude) is constituted as the only vestige that remains of the old Las Cañadas edifice. After its collapse, this steep formation composed of reddish and ocher phonolitic lavas remains. At this point we are at the border with the municipality of San Juan de la Rambla to the west. The flora and fauna of the place are dominated by the Canary pine, cedars and black nightshade, as well as by the common canary, the great spotted woodpecker, and the Tenerife blue chaffinch.
