The most scenic and iconic train journey departing from Lucerne is undoubtedly the Lucerne-Interlaken Express, which forms the first leg of the famous GoldenPass Line. This premium panoramic train takes approximately two hours and traverses the heart of Switzerland, passing five crystal-clear mountain lakes (including Lake Lucerne, Lake Sarnen, and Lake Lungern) and numerous cascading waterfalls. The highlight of the trip is the steep ascent over the Brünig Pass, where the train utilizes a cogwheel system to navigate the rugged terrain. For the best views of the turquoise waters of Lake Brienz as you approach Interlaken, it is highly recommended to sit on the right-hand side of the train when departing from Lucerne. Another spectacular option is the Gotthard Panorama Express, which begins with a nostalgic steamboat cruise across Lake Lucerne to Flüelen, where passengers transfer to a first-class panoramic train that climbs through the original Gotthard mountain route toward Lugano. Both journeys offer floor-to-ceiling windows, ensuring that you don't miss a single snow-capped peak or picturesque Alpine village along the way.
