The Pyrenees (pron.: /ˈpɪərɨniːz/; Spanish: Pirineos or Pirineo, French: Pyrénées, Aragonese: Perinés, Catalan: Pirineus, Occitan: Pirenèus, Basque: Pirinioak or Auñamendiak), also spelled Pyrénées, is a range of mountains in southwest Europe that forms a natural border between France and Spain. It separates the Iberian Peninsula from the rest of continental Europe, and extends for about 491 km (305 mi) from the Bay of Biscay (Cap Higuer) to the Mediterranean (Cap de Creus).
