Located in the centre of the island of La Palma, Parque Nacional de la Caldera is a huge circle of 8 km in diameter with the appearance of a vast melting pot. The many volcanic eruptions, major landslides, the erosive force of water and the simple passage of time have all helped to shape its geomorphology, converting it into a rugged landscape with slopes of up to 2,000 metres which draw together much of the geological history of the island.

Protecting this vast depression are the highest points on the island, including the Roque de los Muchachos which rises to 2426 metres. The interior of the baisin is covered with a dense vegetation and contains high waterfalls and deep gullies. It is furrowed by stunning ravines with evocative names. Among them, standing silent witness to the effects of erosion, are numerous peaks and rocks (great needles pointing skywards). In this area of great scientific and geological interest, the flora and fauna is unique. Among the local species are to be found a large number of species endemic to the Canary Islands.
