From Wikipedia:

Parque Nacional de la Caldera de Taburiente is a national park on the island of La Palma, Canary Islands. It contains the enormous expanse of the Caldera de Taburiente, once believed to be a huge crater, but nowadays known to be a mountain arch with a curious crater shape, which dominates the northern part of the island. It was designated as a national park in 1954.

The caldera is about 10 km across, and in places the walls tower 2000 m over the caldera floor. The highest point is the Roque de los Muchachos on the northern wall, at 2423 m altitude, which can be reached by road. The telescopes of the Roque de los Muchachos Observatory are situated very close to the summit.
