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 . 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.
