Cerro Gordo volcano Nature · Granátula de Calatrava, Campo de Calatrava, Ciudad Real A volcanic cone with a major axis of one thousand metres and a relative height of ninety metres, concealing in its depths 830 metres of magma, earth and sediment; although it recalls the silhouette of a traditional volcano, with a steep mountain and a crater at the summit, it is in fact a cinder or pyroclastic cone, formed over successive volcanic and hydrovolcanic phases. Turned into a volcano-museum after its opening on 15 April 2016, it is the first volcano on the Iberian Peninsula open to visitors, with educational trails explaining the volcanism of the Campo de Calatrava. It is reached from the road between Almagro and Granátula de Calatrava. Photo: Aristoteles jerez (CC BY-SA 4.0) What to see and do in Granátula de Calatrava
