Walchensee is one of Germany's deepest and largest alpine lakes, reaching a maximum depth of 192 meters. Situated in the Bavarian Alps at an elevation of 801 meters, the lake is known for its intense turquoise coloration caused by calcium carbonate content. The lake is fed by high-altitude streams, keeping water temperatures relatively cool even in summer. It serves as a major reservoir for the Walchensee Hydroelectric Power Station, utilizing the elevation difference with the neighboring Kochelsee. The area is a hub for windsurfing and kitesurfing due to consistent thermal wind patterns. The lake is surrounded by mountainous terrain, including the Herzogstand and Jochberg peaks. Motorboats are prohibited on the lake to protect water quality and preserve tranquility. It is a site of significant geological interest, featuring a landscape shaped by glacial activity.
