Hopfensee is one of the warmest lakes in the Bavarian Alpine foothills, reaching temperatures of up to 24°C in summer. Located near Füssen, the lake is situated at an elevation of 783 meters and offers a surface area of approximately 1.94 square kilometers. Its location provides an unobstructed view of the Tannheimer Mountains and the Ammergau Alps. The surrounding 7-kilometer path is paved and suitable for walking, cycling, and wheelchair access. The lake is fed by several small mountain streams and is relatively shallow, with a maximum depth of approximately 10 meters.
