Kumistavi owes a famous legend about Amirani for the sonorous naming of the “Cave of Prometheus.” The legend says that Amirani, like Prometheus, angered the Gods and was punished brutally. The eagle tormented him, eating his liver; however, unlike the Greek giant, cruel Gods were chained. Amirani, not to the rock, but inside a massive cave. Khvamli Mountain is visible from Prometheus Cave, where the legend says Prometheus was chained. Spectacular views of stalactites, stalagmites, petrified waterfalls, underground rivers, and cave lakes. The cave has colourful lights, ranging from orange-red to pink and blue.
