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 [[Dike (geology)|dikes]] piercing the massif, its surface exposes numerous outcroppings of both [[phonolite|phonolitic]] and [[trachyte|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.
