The national park is the product of large-scale landslides through multiple volcanic eruptions that have occurred over the centuries. The geology of the park is composed of a special cirque of more than 8 km in diameter with a form of boiler from which it takes its name. From its summits, such as the Roque de los Muchachos or La Cumbrecita, at the back of the Caldera, the water, which is always present, is precipitated in a multitude of streams and waterfalls, along a gradient that sometimes reaches 2,000 meters. In addition to its impressive landscapes, it is important to emphasize the presence of a wide variety of plant and animal species, many of which are only exclusive of the habitats of the Canarian archipelago.
