is the name of Spain’s highest mountain in the middle of Tenerife. At 3718 m, Teide is the third largest island volcano in the world and towers over the entire Canary Islands. Around the Teide there is a plateau about 20 km in diameter, the so-called caldera. The caldera is framed in places by 500m high cliffs, although it is already at an altitude of over 2000m. It is a surreal experience to drive through the caldera and you feel as if you are in another world. Bizarrely shaped basalt structures from the cooled lava flows stretch as far as the eye can see, and in many different colours.
