Massifs
The Anaga massif (Macizo de Anaga), at the northeastern end of the island, has an irregular and rugged topographical profile where, despite its generally modest elevations, the Cruz de Taborno reaches a height of 1,024 metres. Due to the age of its material (5.7 million years), its deep erosive processes, and the dense network of dikes piercing the massif, its surface exposes numerous outcroppings of both phonolitic and trachytic origin. A large number of steep-walled gorges are present, penetrating deeply into the terrain. Vertical cuts dominate the Anagan coast, with infrequent beaches of rocks or black sand between them; the few that exist generally coincide with the mouths of gorges.
The Teno massif (Macizo de Teno) is located on the northwestern edge of the island. Like Anaga, it includes an area of outcroppings and deep gorges formed by erosion. However, the materials here are older (about 7.4 million years old). Mount Gala represents its highest elevation at 1342 metres. The most unusual landscape of this massif is found on its southern coast, where the Acantilados de Los Gigantes ("Cliffs of the Giants") present vertical walls reaching heights of 500 metres in some places.
The Adeje massif (Macizo de Adeje) is situated on the southern tip of the island. Its main landmark is the Roque del Conde ("Count's Rock"), with an elevation of 1001 metres. This massif is not as impressive as the others due to its diminished initial structure, since in addition to with the site's greater geologic age it has experienced severe erosion of its material, thereby losing its original appearance and extent.
