Fascinating place on the tourist island of Tenerife. About a 2 hour coach ride up from the seaside resorts. It has moonscape like elements and lots of rock formations around the slopes of the giant volcano. There is a cable car to the top of the volcano from the coach park on the higher slopes, or you can walk up if brave.

Unique environment for plants and insects at such a high altitude with the volcano rising directly from the ocean. 

We booked a coach tour from our hotel but you could easily hire a car and drive up as you would have more time to explore and not have 50 people following you in a group.

Tip: take warm clothing as it can be very cold and windy at the top even if it is scorching down in the resorts!
