One of the best places in the northern hemisphere to stargaze is the Observatorio del Teide. Set just off the C-824 highway that runs between La Laguna and the El Portillo visitor centre, scientists from all over the world come to study here and at its sister observatory in La Palma. You can have a free tour and add your name to the list of those who’ve seen through the mammoth telescopes scattered here from December to March. You’ll need to make an appointment first. For more information, see www.iac.es.
Volcano Life Experience (www.volcanolife.com), a private tour company, also offer a number of stargazing packages starting from €30 per person.
