Teide National Park is situated on the Spanish island of Tenerife, part of the Canary Islands in the Atlantic Ocean off the coast of Africa. In 2007 it was declared a World Heritage Site by UNESCO. It is the most visited national park in Europe. The park is dominated by Mount Teide which at over 12,000 feet is the highest peak in Spain. Mount Teide is still an active volcano, the last eruption being in 1909. The entire park is a unique geological treasure in which the volcanoes, craters, vents, lava flows and different materials, form an impressive array of shapes and colours. The caldera of the volcano is a giant amphitheatre at around 6,500 feet above sea level and it frequently sits above the cloud level around the coasts of Tenerife below, enjoying wonderful clear skies.
