Last Saturday I took a day trip with some friends to see some pretty cool natural geological formations and some man-made creations. It was a looooong day, we left Jerez at 7:45am and returned at 8pm, but it was well worth it.
The first stop: La Gruta de Maravillas

You weren’t allowed to take pictures inside s
o I had to take these from the internet. La Gruta is located in the town of Aracena, which is about two hours from Jerez. It was first opened to the public in 1914 and was one of the pioneers of subterranean tourism in Spain. Walking through it was like exploring an alien world; weird geological formations hung from the cavern ceiling or emerged from the ground surrounded by beautifully brilliant blue pools; the humidity was at 100% and water dripped or flowed from from almost every crevice and geological structure making it impossible not to get wet. The caverns were astonishing; the organic shapes created seemed as if they were the imagination of Jules Verne, taken out of Journey to the Center of the Earth. With appropriately named room like the sala de garbanzos because of grabanzo-like formations on the floor and sala de erotica because of phallic-like structures protruding from the walls; it was unlike anything I had ever seen.

The second stop: Las minas de riotinto (The red river mines)


The mines have a very long history dating back to Roman times, but not coming into their own until 1873 when they were bought by a British company. From then on out they played an important role in the extraction of metals up until their closure in the late 90s early 2000s. At their peak production, the nearby town of riotino boasted a population of over 200,000 compared to a mere 4,000 today. The mines themselves and the surrounding area create a surreal, almost mars like atmosphere; everything is tinted in dusty pinks, brown, yellow and gray. The scale of the mines is so big it consumes the area around it, mostly devoid of trees and plants they sit like a scar on the landscape that will never heal.
The last stop: Niebla
