Lanzarote is a Spanish island, the easternmost of the autonomous Canary Islands in the Atlantic Ocean, approximately 125km off the coast of Africa and 1,000km from the Iberian Peninsula. Covering 845.94km2, it is the fourth-largest of the islands in the archipelago. With 141,938 inhabitants, Lanzarote is the third-most populous island of the Canary Islands, after Tenerife and Gran Canaria. In the centre-west of the island is the Timanfaya National Park, which is one of the main attractions of Lanzarote. Its capital is Arrecife.The first recorded name for the island, given by Angelino Dulcert, was Insula de Lanzarotus Marocelus, after the Genovese navigator Lancelotto Malocello, from which the modern name is derived. The island's name in the native language was Tyterogaka or Tytheroygaka, which may mean "one that is all ochre" (referring to the island's predominant colour).GeographyLanzarote is located 11km north-east of Fuerteventura and just over 1km from Graciosa. The dimensions of the island are 60km from north to south and 25km from west to east. Lanzarote has 213km of coastline, of which 10km are sand, 16.5km are beach, and the remainder is rocky. Its landscape includes the mountain ranges of Famara (671m) in the north and Ajaches (608m) to the south. South of the Famara massif is the El Jable desert which separates Famara and Montañas del Fuego. The highest peak is Peñas del Chache rising to 670m above sea level. The "Tunnel of Atlantis," the largest underwater volcanic tunnel in the world, is part of the Cueva de los Verdes lava tube.
