This theme park, extending across the village and the surrounding area, boasts an incredibly unique landscape created over 5 000 years by the mining for minerals and metals. The main sights are the mining museum, the mine train, Casa 21 and the Peña de Hierro mine. Take in the unexpectedly beautiful view over this landscape of craters from the impressive Corte Atalaya and Cerro Colorado, Riotinto's second largest open-cast mine.
