Land of mines, land of pastures, land of mountains...
The dehesa is the most representative landscape of the municipality, mainly occupying the slate and granite areas, on shallow, acidic soils. It is a resource of high environmental and ecological value. In El Castillo de las Guardas, the dehesa stands out as the habitat of the fighting bull, although there is also an abundance of game species such as deer, wild boar, rabbit, woodcock and partridge.
Former mining operations are to be found in the municipality of El Castillo de las Guardas. These soils, occupied by old mining operations, constitute a characteristic and peculiar landscape.
A few kilometres from the town centre, in its municipal district, is the El Castillo de las Guardas Reserve, one of the largest parks in Europe, where the animals live in semi-freedom and located on the land of a former mining operation.
