What is it? Tenerife is dominated by Mount Teide, a dormant volcano that is Spain's tallest peak. The peak is surrounded by a stunning national park, where you can go stargazing thanks to the clear night skies.
Why go? From Teide you can see 83 out of the 88 registered constellations in the sky. A guide will walk you through the history of the skies, and even give you the chance to see the Andromeda Galaxy, a staggering 2.537 million light years away, using a telescope. Finish the night off with tasty tapas at the foot of the volcano.
