The volcano that formed the island of Tenerife, it’s peak is a massive 3718 meters above sea level, over twice the height of any mountain in the UK (and also making it the highest point in Spain).
The volcano is part of the Teide National Park, which UNESCO has named as a World Heritage Site. The volcano itself remains active, the last eruption being in 1909.
Today the volcano is popular with walkers, many of whom climb to its summit. Others feeling less active often take tours in its general vicinity to see the remarkable landscape the volcano has produced.
