The true beauty of the caves is hidden for the eyes for centuries. If you want to taste this beauty, you have to see through the ubiquitous darkness and try to hear the cave silence. You will hear the falling water droplets or distant roar of subterranean river. A whiz of the bat wings reminds you that you are not alone there. Only then you begin to perceive the true face of the cave through its damped sounds. We tried too catch some of them for you in the tunnels of the Sloup-Šošůvka caves. Do not believe?
