Plitvice Lakes National Park, Croatia. The Plitvice Lakes National Park is a treasure of Croatian natural heritage. The main attraction of this unique park on a global scale is 16 lakes connected with 92 waterfalls. What determines the uniqueness of the park, however, is the color of the water. Her photos look like a photo montage, but they are not. The lakes are turquoise, emerald and sapphire. You can admire them from narrow, wooden footbridges, stretched just above the surface of the water
