The island of Mljet has two beautiful lakes that are on the western end and are connected by a channel of equal beauty. Both are in the national park and the joining channel is subject to tidal flows. Surrounded by small mountains and completely green forested areas these two lakes have a spectacular beauty. One of the best things about the island of Mljet is that you see water everywhere. The waters are a dramatic deep blue and you always feel like diving into them. Unlike other national parks, visitors here can enjoy themselves by bathing in the waters. Normally they are not deep and are home to thousands of animals, so, hundreds of people come here for diving.
