Boat trips to Lake Lucerne are a must-see experience. Take a boat ride at the Luzern train station pier and see Mount Pilatus and St. Regis. Of course, if you choose the famous Golden Tour project of Mount Pilatus (including Lake Lucerne Tour), then the separate Lake Tour project can be cancelled. If you don't choose a golden tour, then the Lake Lucerne cruise will surprise you. We were lucky enough to see the double rainbow after leaving Lucerne train station. Lucerne's sunny and cloudy days are equally intoxicating and obsessive.
