Shore-entry Lake Zug dive with plateaus, fish, and a deeper wall option.
Rossblatten is a shore-entry Lake Zug dive with a gentle start, several plateaus, and a wall-like section that becomes more interesting as you head right. The route stays friendly in the shallows but still offers a proper lake profile for divers who want to go deeper, with seagrass, lake fish, and the kind of sandstone and boulder scenery that makes freshwater diving feel varied rather than flat.
