Lake Lucerne

Usually the visibility in Lake Lucerne is better than in Lake Zurich. Despite of its bigger size there are less dive sites because access to the lake is not possible (rock or private ground). The best dive sites are Weggis-Vitznau, Hergiswil and Beckenried, where is a sunken conveyor sistems from the time where the Seelisberg tunnel was built.
