El Golfo depression, with its sheer faces, covers the northwest façade of the island and is probably the bottom of an ancient crater. The rim is covered with laurels and giant heather while the level bottom is cultivated. There is an excellent view from the Mirador de la Peña, built by César Manrique at 700m above sea level. The famous rocks of Salmor are further north. Closer to hand, the Fuga de Gorreta, is home to a species of primeval lizard.
