Plitvice Lakes National Park is one of the greatest natural wonders of Europe. Embraced by high wooded mountains, one beneath another lies sixteen beautiful lakes of crystal blue-green water. Connected to each other by a series of foaming cascades and thundering waterfalls, the lakes are fed by many rivers and streams. Over the millennia, waters of these lakes have dissolved the limestone rock and carved out the valley in which they now lie. Clouds of butterflies drift above the 18 km of wooden footbridges and pathways which snake around the edges and under and across the rumbling water. No wonder that the Plitvice Lakes were granted UNESCO World Heritage status in 1979. and since then has been the most visited national park as well as one of the most visited destination in Croatia.
