Lake Lucerne is located in central Switzerland and extends across the four cantons of Uri, Schwyz, Unterwalden, and Lucerne. With a surface area of 114 km² and a depth of 214 meters, the lake is one of the region's most important bodies of water. The water level is regulated by the needle weir built in Lucerne.
Numerous sites around the lake are of great historical significance for Switzerland: These include the Rütli, the Tellsplatte, the Tell Chapel, the Schnitzturm (Carved Tower) in Stansstad, Neu-Habsburg, the Schillerstein, Treib, the Astrid Chapel in Küssnacht, and Meggenhorn Castle.
Lake Lucerne can be reached comfortably and environmentally friendly by ÖBB nightjet and during the day by ÖBB railjet via Zurich.
