The elongated Bischolsee, also known as the Bischolasee, is located on Heinzenberg at an altitude of 1,993 meters. The lake is under nature protection and therefore it is not allowed to swim in it. But don't worry, just a few steps away you can hop into the Pascuminersee. The view from the lakefront of the mighty Piz Beverin is simply wonderful and with a little luck the summit will be perfectly reflected in the surface.
