Tenerife: Teide

Challenging rock climbing route, starting at an altitude of 2350 m above sea level, and continueing till the top of the Teide (vulcano top) at 3718 m. Note that the last 200 meters can only be climbed with a written permission.
My impression is that the track can be taken without being extremely trained. Be shure to watch the weather (wind, temperature, and perciptiation), and verify the snow state of the track.
Note also that the track-end is actually at an altitude of 3718, although the (automatically generated) altitude graph shows a somewhat lower value.
