The Cueva del Agua de Tíscar is a natural limestone cave excavated by the stream of Tíscar in a closed canyon, next to the sanctuary and the castle of Peña Negra. The water has shaped a narrow gorge with waterfalls, pools and a short gallery of very low access, so that the place combines geological features, landscape and a strong popular charge linked to the Marian tradition of Tíscar. From the point of visit it is possible to observe the encasing of the rock, the small passage excavated under the road and the humid atmosphere of the riverbed, with the water channeled between traditional orchards. In times of greater flow the whole gains visual force by the jumps and the sensation of cave-vadillo, while in low water the form of the gorge and the erosive work of the current is better appreciated. The local tradition locates here a Marian apparition, and the place appears mentioned in tourist and informative guides of the surroundings of Cazorla like one of the most well-known enclaves of Tíscar. It is in the Natural Park of the Sierras de Cazorla, Segura and Las Villas, although the cave itself is visited as a scenic and cultural point rather than as a speleological cave. The best time to visit is usually in spring or after rainfall, when the water provides more visual and sonorous presence. On sunny days in the morning or afternoon, the light enters the narrow access better and the whole can be seen with more contrast.
