The Teno massif is one of three volcanic formations that gave rise to Tenerife, Canary Islands, Spain. It is located in the northwestern part of the island between the towns of Santiago del Teide, Los Silos, El Tanque and Buenavista del Norte. The volcanic massif, emerged during the last 5 to 7 million years, is furrowed by deep ravines and ends abruptly in the sea, in an area known as Los Gigantes, a series of high cliffs that plummet over the sea. The villages known as Masca, Teno Alto, Los Carrizales, El Palmar, Las Portelas and Las Lagunetas preserve the old agricultural traditions of Canary Islands.
