Most prominent and oldest national park in Croatia, Plitvice Lakes, was added to UNESCO's World Heritage List back in 1979. It Situated halfway between Zagreb and Zadar, marked on old maps as the “Devil’s Garden”. The main attraction of this park, unique in the world, are 16 small lakes connected by cascading waterfalls created by deposition of travertine, a special kind of limestone. Park includes the spring of the Korana River in the area surrounded by dense beech forests, fir and spruce, partly in the form of primeval virgin forest. Apart from the lakes and forests the park also contains many caves, springs, flower meadows, and among other preserved animal species he brown bear stands out. It is hard to say whether the park is more beautiful in the spring when flowers blossom on its meadows, while the colorful reflections of autumn colors the mirror-like lakes, or perhaps in the winter peace in snowy landscape and iced waterfalls.
