… Amazing place used as the setting for other Hollywood movies including Tarzan, incredibly marvelous cave complex has now been open for nearly 100 years- Aracena’s Cave of Marvels (Gruta de las Maravillas).

…Haunting site which has been wowing thousands of tourists each year since 1914, when it was first opened.

To create this dream-like underworld, nature has worked silently for 550 million years forming 12 chambers and six underground lakes which can be explored through tunnels on a one kilometer route over three levels.

The shapes are formed when carbonate-based rocks come into contact with water and start to dissolve. The resulting rock formations are truly remarkable, with stalactites and stalagmites creating wonderful shapes ranging from the delicate to the spiky – and not to mention the distinctly phallic. Visitors will marvel at the bulbous shapes in the once-flooded ‘Chickpea Chamber’, and the intricate formations in the Chamber of God’s Crystal, a vault that was formed some 50,000 years ago.

Locals referred to the caverns as a ‘water well covered in snow’ due to the white formations – from which the street at the cave entrance takes its name, Calle Pozo de la Nieve.

Aracena– a town and municipality located in the province of Huelva, south-western Spain.
