The region of Valencian Community lies in the East of Spain. It borders Catalunya in the North, with Aragon and Castilla la Mancha in the West, with the region of Murcia in the South, and with the Mediterranean Sea in the East. Valencia's geographical landscape can be divided into two parts: inland and coast. Mountains and rock formations integrated into the Iberian mountain range and the Subbetica range dominate the landscape inland. Some of the most notable mountain formations include the Maestrazgo, Martes, Espina, and Espadan sierras as well as Caroig Massif. The areas highest peak is in Penyagolosa and reaches 1,813 Mts. high. The Penibetico range penetrates the region from the South in Alicante forming various other sierras including Crevillente, Carrascal and Aitana, whose peak reaches 1,558 Mts. tall. The second part of the region is located around the flat coastal area, mainly comprised of low sandy beaches and coastal lagoons and pools, some of which have dried up. The most notable natural landmarks are Salinas Point, Cape Irta, Cape Oropesa, the Columbretes Islands (of volcanic origin and declared a nature reserve in 1998), Benavides Ravine, Estany, Colomer and Palos passages, the tourist beaches of Canet, Puig, Natzaret, Pinedo, Saler and others very close to the city of Valencia, Cullera Point (with the small island of Peñeta del Moro in front of it), Xeresa Beach, Oliva Beach, Gandia Beach, Venecia Beach, Piles Beach, Almadraba Point, Cape San Antonio, Cape Nao, Ifach Rock, Cape Las Huertas, the Bay of Alicante, the Cape and Bay of Santa Pola and Cape Cervera. The rivers in the region of Valencia are generally short, with small quantities of water. Some of these rivers are: Mijares, Palancia, Turia, Jucar, Cabriel, Magro, Serpis, Vinalopo and Segura.
