Photos simply cannot do justice to the spectacular sight of this eight-kilometre-wide cleft that reaches depths of up to one and a half kilometres, covered by dense Canarian pine woods, and criss-crossed with deep ravines: you just have to see it in person. The Caldera de Taburiente National Park in the centre of the island of La Palma is the number one attraction of the island known as “La Isla Bonita” (“The Beautiful Island”), a Unesco Biosphere Reserve. Here, nature guards a valuable treasure of geological and biological diversity.
