The Canary Islands belong more to Africa than Europe, and although there is the highest mountain of Spain – Pico de Teide (3718 m above sea level), which for about 250 meters altitude exceeds the highest mountain in the Iberian Peninsula and the „mainland“ of Spain – Mulhacen (3479 m asl) . Teide volcano is absolutely dominant greatly exceeding their surroundings. Moreover, its peak lies only 13 km as the crow flies from the sea. Yet all this is only a small remnant of a giant volcano that exploded before 700,000 years ago and left her an enormous caldera diameter of fifteen kilometers, which now falls under the National Park of Las Canadas del Teide. According to some calculations, could have the original volcano and ten kilometers tall and would be the world's tallest mountain.
