Caves Of Nerja
The second most beautiful cave in Spain that you should not miss is Caves Of Nerja. These caves are near the coastal town of Nerja in Andalusia, Spain's southernmost region. They were discovered in 1959 by a few local teenagers on a night walk looking for bats. They are famed for their rock formations, but some prehistoric paintings and sketches have also been discovered.
The caves, which have been open to the public since 1960, are separated into various halls, each named after a certain type of stalactite or stalagmite found in them. The yearly International Festival of Music is hosted in the Hall of Waterfall (stalactites producing a rock waterfall). Another hall is home to the world's largest stalactite. Tunnels, bridges, and pathways connect all halls and caves, with many stairs in between. If you wish to visit the Nerja caverns, be prepared to walk a lot and wear sturdy shoes.
