Platonovo šepetanje (Plato’s whisper) is 560m deep cave on a carst plateau above Pokljuka, Slovenia. We have been researching this cave for several years. This was a second photo excursion into this cave (photos from first photo excursions are here) with the aim to take pictures from upper part of the cave (down to -250m). Photo excursion to the bottom is planned this autumn.
