The Cuevas de Fuentemolinos is a 4km long cave with three levels, each level is just a single horizontal passage. The cave is developed in Oligocene limestone conglomerate, which is rather rare. It is noted for an abundance of seleothems including rimstone pools, calcite spars, soda straws and helictites. The cave is a river cave, the river flows through most of the lower level and the entrance is the resurgence.

The cave is closed but there are guided spelunking tours offerd by a local organizer named Beloaventura. The tours shw about 1,300m of the cave, participants are equipped with full caving gear including overall, wellingtons, helmet, head lamp, and gloves. A drop on the route is climbed with a fixed wooden rope ladder.
