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 Teno Rural Park has an area of 8063 hectares, and is characterised by basaltic lava flows and a plant and floristic diversity that varies widely with each insular microclimate.
Euphorbia balsamifera and Carthamus lanatus, a variety of thistle, can be found in coastal areas.
The European Union has designated the Macizo de Teno as a special area for the protection and conservation of the large colonies of pigeons that inhabit the laurel.
The area also contains archaeological ruins, with the stone edifices belonging to the ancient Guanche inhabitants of the island.
