Lac de Tseuzier, reservoir in Switzerland
Lac de Tseuzier is a large reservoir in Valais, Switzerland, located at about 1777 meters (5837 feet) surrounded by forests and green mountain slopes. The bright green water is held back by the Rawyl Dam, which manages mountain stream flow and makes space for walking trails around the water.
The lake was created by the construction of the Rawyl Dam in the late 1950s, standing over 150 meters tall and holding more than 50 million cubic meters of water. The region has a long history of water management, shown by the Grand Bisse d'Ayent, an ancient irrigation channel system that dates back centuries.
The lake is used by both locals and visitors who value the quiet and mountain surroundings. The place connects traditional alpine farming with modern water management, showing how communities have lived and worked in these mountains for generations.
The lake is easily accessible from spring to autumn with free parking at the dam and good walking trails around the water. Comfortable shoes, water, and snacks are recommended, and in bad weather or winter the roads and paths can become difficult or unsafe to navigate.
Over 300 climbing routes of varying difficulty levels surround the cliffs of the region, drawing both beginner and experienced climbers. The nearby Wildhorn mountain also offers beginner-friendly glacier walks with guides, making it possible to experience the heart of the Alps.
