Lausanne's famous tourist destination can be reached by walking for about ten minutes after leaving the railway station. On the way to meet the very enthusiastic elderly, help us walk the path, more convenient than the navigation of Google Map. The Olympic Park is also very interesting. There is a museum in it. Before the Rio Olympics, there are various Rio elements. There are runways, memorial statues of Coubertin and cafes in the park. There's a big fountain coming out of another gate in the park. It's worth going.
