The uneven and steep orography of the island and its variety of climates has resulted in a diversity of landscapes and geographical and geological formations, from the Teide National Park with its extensive pine forests, juxtaposed against the volcanic landscape at the summit of Teide and Malpaís de Güímar, to the Acantilados de Los Gigantes (Cliffs of the Giants) with its vertical precipices. Semidesert areas exist in the south with drought-resistant plants. Other areas range from those protected and enclosed in mountains such as Montaña Roja and Montaña Pelada, the valleys and forests with subtropical vegetation and climate, to those with deep gorges and precipices such as at Anaga and Teno.
