You're standing at the Cueva del Sidrón, a cave in the municipality of Piloña, in green Asturias in northern Spain. Take a look at the landscape around you. Beneath your feet lies limestone, and over a very long time, water has carved a huge network of passages into it. Altogether about 3,700 metres long, with a central hall of 200 metres.
