This boat passes through some of the lakes of Plitvice Natural Park. The Natural Park, a UNESCO World Heritage Site, is very extensive, and to move from lake to lake, it's sometimes more convenient to go by boat. There are a half dozen ships that sail the 16 lakes, making round trips to cut down your voyage. You also get another perspective, from the water, of this incredible natural location. When it's sunny, it's even more incredible, the water turns many different colours because it's so pure and transparent that it lets light through, allowing you to see all the way to the bottom. The price of the boat is included in your entrance ticket to the park, which is 13 euros, and you can get on and off as much as you want all day.
