We're driving back from Altdorf and the Clear-Blue Skies lure us into making an impulsive stop. We decide to walk through the Reussdelta. This is where the River Reuss flows into Vierwaldstättersee (Lake Lucerne) in the canton of Uri. It's a mosaic of shallow water and reed beds.

Wooden bridges, Towers and Observation decks offer stunning views of the surrounding mountains. Unlike us mere mortals clad in jackets and sticking to the confines of the decks, the ducks are at home in the frigid waters of the lake.
