Another amazing place that I was lucky enough to visit again was Koněpruské jeskyné. This time, the photography was significantly more difficult, because you are in extremely dark places during the entire tour; the cave spaces are only sporadically lit. But in today's day and age of SLR cameras, where it is not a problem to use high sensitivities, and with the help of fine-tuned and sophisticated algorithms of photo editing programs, excellent results can be obtained even under such extreme conditions.

The Koněpruské caves are located inside the Zlatý kůň hill above the village of Koněprusy in the Český karst PLA, about 5 km south of the district town of Beroun. The caves are the longest cave system in Bohemia. It is an extensive three-story cave system built in Devonian limestone with a height difference between the individual floors of about 70 meters.
