Teide National Park.
The Teide National Park occupies the highest area of the island of Tenerife (in the Canary Islands) and Spain. Declared on January 22, 1954 as a National Park, it is the largest and oldest of the national parks of the Canary Islands and the third oldest in Spain. In 2007 it was declared a World Heritage Site by Unesco, and also since that year it is considered one of the 12 Treasures of Spain.
In this area is the Teide volcano (in Guanche and originally, Echeyde or Echeide) that with its 3718 meters, is the highest peak of the Canary Islands, Spain and any land emerging from the Atlantic Ocean. It is also the third largest volcano in the world from its base in the ocean floor, surpassed only by Mauna Kea and Mauna Loa in Hawaii. The height of the Teide also makes the island of Tenerife the tenth highest island in the world. Next to the Teide is the second highest mountain of the Canary Archipelago, the Old Peak with 3135 meters above sea level, both being the only Canarian mountains that exceed 3000 meters of altitude.
