To visit Ruegen means to visit Sassnitz. In fact, Sassnitz was the first seaside resort on Ruegen. The city has a 1,444 km. long harbour wall, the longest in Europe. It gives a certain air of permanency to the harbour, where passenger ships, sports boats and a small fishing fleet all dock. The city borders on the Jasmund National Park and its picturesque chalk coastline, the Koenigsstuhl and the Wissower Klinken are well known all over Germany.
