Quintessential Croatia here. Only time I've ever seen water more clear was in the ADK High Peaks and Greece. This park is real unique with numerous waterfalls. A Unesco World Heritage site and totally protected. It must have been 95 the day we went there and with all the no swimming signs it was pretty depressing UNTIL, back at the little electric ferry dock I hiked off in the woods to take a quik leak and heard girls frolicking and the sound of splashin waters. Called the gang over and a short hike thru the trees found us in a secluded clandestine swim area with Croat girls sunbathing and in the waters. It was like a ancient vision from the Gods . We jumped right in !
