Observatorio del Teide (954 TEN)

Right from the start, this climb heads straight up to the Teide Observatory (954 TEN), with about 2000 meters of elevation—so come prepared. Once you reach the observatory, take a moment to soak in the views. If you need to refuel, you’ll need to ride a bit further to El Portillo. Otherwise, turn back and enjoy the long descent. The last 15 kilometers run parallel to the coastline, leading you back to where you started.
