The Calares del Mundo and Sima Natural Park is a natural space of enormous diversity and chromatic richness located southwest of the province of Albacete. It covers a total of 19,192 hectares between the towns of Riópar and Villaverde de Guadalimar. In the interior of the Park, 85 underground cavities have been explored, highlighting the Chorros cave, considered the most important cave in the south of the peninsula, with more than 50 km of explored galleries. The cave opens into a large vertical wall that closes the valley in a semicircle. It is here where the Mundo River is born, forming a spectacular fall of more than 80 meters and small pools of water called calderetas.
