The islands are of volcanic origin and emerged approximately 10 million years ago as a consequence of volcanic eruptions on the ocean floor. From a geographical point of view The Canary Islands are part of Africa, but from a political point of view the islands belong to Spain since the 15th century.
Tenerifehas a surface of 2057 square kilometres and is the largest island of the group. It has the shape of a triangle with its longest point towards the North-East which emerges in a peninsula, around the massif of Anaga. In the West you find the massif of Teno and the extreme Southern point of the island lies precisely on the 28th latitude.
The island is divided in two by the volcanic territory of Las Cañadas, a large desolate plain of gravel and volcanic stones with in his centre the Pico del Teide, a crater of 3718 meters which is the highest point of Spain.
Referring at the snow-covered top of the Teide, the original occupants of Tenerife, the Guanches, gave the island the name "Tinerfe" which means as much as “the island with the white mountain" or "the island with the snow-mountain”.
As these mountains stop the trade winds and keep the clouds above the Atlantic Ocean, they form a climatological barrier. The North of Tenerife is often cloudy and sometimes even rainy. Thanks to its wet climate the subtropical vegetation of the north of the island is very rich and the landscapes are green.
In the South the temperature is extremely mild, the whole year trough. The winters are moderated and the summers are dry and torrid, although temperature the temperature seldom exceeds 30 degrees. The evenings are often delightfully fresh, thanks to a fresh ocean-breeze.
