Avatar’s lush Pandora? Or … Eastern Europe. Yes on both counts. This light-filled fantasyland of terraced waterfalls is Skradinski Buk, the most enticing corner of Croatia’s Krka National Park. The park, also a UNESCO World Heritage site, was founded in the mid-80s to protect the verdant lands along the Krka River; it has since become a major attraction for both Croatians and foreign tourists. It’s no wonder -- who could resist standing in the sunlight beneath one of Skradinski Buk’s 17 different cascades, letting the water pound down on your shoulders in what is nature’s own massage?
