Teide National Park

Teide National Park is the geological heart of Tenerife: a 190 km² caldera 2,000m above sea level, dominated by the snow-capped volcanic summit that gives the park its name. UNESCO inscribed it in 2007 as much for its scientific value as its raw beauty — endemic plants like the Teide violet survive nowhere else on Earth, and the clarity of the night sky has made the park one of the world's top three astronomy sites. Visiting is best as a full day from the coast: the cable car climbs to 3,555m in eight minutes, the Roques de García circular walk gives the iconic photo, and the Mirador de Chipeque viewpoint catches a sea of clouds at sunset. Serious hikers should overnight at the Parador (the only hotel inside the park) to attempt the dawn summit walk, which requires a free permit booked months in advance. Best for travellers who treat Teide as a destination in its own right, not a half-day add-on.
