The remaining regions of Spain are the Balearic and the Canary Islands, the former located in the Mediterranean Sea and the latter in the Atlantic Ocean. The Balearic Islands, encompassing a total area of 5,000 square kilometers, lie 80 kilometers off Spain's central eastern coast. The mountains that rise up above the Mediterranean Sea to form these islands are an extension of the Sistema Penibetico. The archipelago's highest points, which reach 1,400 meters, are in northwestern Majorca, close to the coast. The central portion of Majorca is a plain, bounded on the east and the southeast by broken hills.

The Canary Islands, ninety kilometers off the west coast of Africa, are of volcanic origin. The large central islands, Gran Canaria and Tenerife, have the highest peaks on Gran Canaria they rise to 1,950 meters and on Tenerife, to 3,700 meters.
