Known as the jewel of Kastoria, legend says that the Cave of the Dragon was once a gold mine guarded by a dragon who breathed poison to deter anyone from entering.
The cave opened to anyone willing to brave the dragon’s fumes in 2009, and as yet, no-one has been poisoned. There are seven underground lakes and ten caverns of various sizes connected by corridors and tunnels.
The cave is of paleontological interest, and there are bear bones in the cave which are estimated to be 10,000 years old.
