In the heart of Tenerife, and 2400 meters above the sea, is the Observatorio del Teide. While its sister observatory on the island of La Palma is mainly used for observing the night sky, this observatory is mainly used for observation of the sun.

There are guided tours every week. We joined one of these tours, and had the chance to see the observatory, the inside of one of the buildings, and we also had a look at the sun with a special telescope.
