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.

Beginning of the Pas greenway. The route runs along the old railway line, so there are no large slopes. Ideal for everyone

Somo beach is undoubtedly one of the best Spanish and European surfing spots. There are waves almost every day of the year, there are plenty of schools and the atmosphere is very fun. Somo beach is located between Puntal and Loredo beach, another mythical surfing spot in the north of Spain.
