Cabárceno Nature Park is a unique space in Cantabria, not a conventional zoo, built on a former iron mine. Within its 750 hectares, the animals live in semi-freedom in large natural enclosures. You can explore the park in your own car, on foot, or by cable car to see more than 120 species of animals, such as elephants, bears, and gorillas, in an environment very similar to their natural habitat.
