About this site
Unterwilen sits on the shore of Lake Lucerne (Vierwaldstättersee) in central Switzerland, near the town of Weggis at the foot of the Rigi. Diving in this part of the lake would mean entering the freshwater of the Vierwaldstättersee, with the Alpine terrain around Weggis and the Rigi massif forming the backdrop.
