Geneva and the Matterhorn: Quest for the Water Castle

Water is over-taxed and under-tended in many places but not in Switzerland. Quest for the Water Castle shows how this alpine haven has resisted temptation to bleed its most precious resource.

On Lake Geneva, stops include Lausanne, Nyon and Vevey. In the the Rhone River Valley we visit the Valais, Zermatt and the Matterhorn, and the wellspring of the great river, the glaciers of the Uri Alps.
