La Mina 'El Edén'
It is an exceptional place to visit because of its extraordinary characteristics and it has been voted as one of the most interesting cities in the world. It is a 'must see' for those who are interested in the history of the mining industry that forms the central part of this place. A small train takes you in the mines and is quite an adventure. There is also a small educational center inside that displays mining equipment and provides information about the process.
