Schieferneggtunnel is a shore-entry wall dive located in Lake Vierwaldstättersee. The site features a distinct overhead tunnel environment that requires advanced certification and specific training. Divers typically explore depths between 20 and 30 metres, where water temperatures remain a constant 5 to 6°C. Visibility ranges from 5 to 15 metres, and currents are generally mild. Due to the cold water and confined space, a drysuit or thick, well-sealed wetsuit is recommended year-round. Divers must manage the risks associated with deep, overhead environments and low visibility. A dive shop is located nearby for equipment and cylinder support.
