This is a must stop for all of you who are visiting Tenerife.
Since I was staying at the Costa Adeje, south of the island, I traveled from south to north along the TF-21 road in a rented car, from Vilaflor to Icod de los Vinos, crossing Las Cañadas. It is amazing to see how the landscape changes as you go up.
First you pass the forests of the Corona Forestal Natural Park, the biggest protected natural reserve of the archipelago (more than 46000 hectares).
When you pass the 2700 meters above sea level, the landscape drastically changes and the greenness is substituted by an arid landscape, almost lunar, composed by rocky formations, volcanic cones and craters.
