The Los Tobales Cave of karstic origin, also called the Tragante Cave, is one of the seventy caves to have been discovered in the Sierra Norte. It is located in the surroundings of the Rivera del Huéznar River, in an area formed by Cambrian limestone, which has been perforated by the waters to form the cave, inside which there are numerous stalactites and stalagmites, created by the filtration of water with dissolved calcium carbonate. The name of the cave refers to the rock called limestone tufa, produced by the precipitation of the calcium carbonate contained in surface water or groundwater that crosses limestone terrain.
Access to the interior of the cave is restricted since it is located on private property and is not open to the public. The area surrounding the cave can be accessed via the SE-7101 road in the direction of Cazalla de la Sierra, or via the Sierra Norte Greenway.
