A heart-shaped lake named the most beautiful in Europe, but no one is allowed to bathe in it

The heart-shaped lake known as Lünersee has captured the imagination of visitors from around the world, drawing admiration for its stunning natural beauty and unique appearance. Located high in the Austrian Alps, nearly 2,000 meters above sea level, this glacial lake sits within the Vorarlberg region, nestled at the end of the Brandnertal valley. Surrounded by towering mountain peaks and untouched nature, it has become a favorite destination for hikers and photographers alike. Its turquoise waters and distinctive shape, which resembles a heart when viewed from certain angles, have made it one of the most photographed attractions in Austria.

Lünersee was officially declared the most beautiful place in Austria in 2019 by the Austrian national television station ORF. The lake spans an area of 1.12 square kilometers and reaches a maximum depth of 139 meters. It lies at an altitude of 1,970 meters beneath the imposing Schesaplan peak, which rises to 2,965 meters and is the highest point in the Rätikon mountain range. While originally a natural alpine lake, it underwent significant transformation during the mid-20th century. Between 1955 and 1958, a dam was constructed, converting it into a reservoir to supply water for a hydroelectric power plant. When fully filled, the lake can hold up to 78.3 million cubic meters of water, representing substantial energy potential.

Access to Lünersee is available via two main routes. The fastest option is by taking the Lünerseebahn cable car, which provides quick access to the lake's upper areas. For those who prefer hiking, there is also the "Böser Tritt" trail, known as the "Zli Korak," a steep path leading directly from the parking lot to the lake itself. Near the top of the cable car station stands the Douglasshütte mountain hut, a popular spot for rest and meals featuring traditional Austrian cuisine. Originally located on the peninsula of the former natural lake, the hut had to be relocated to a higher position due to rising water levels caused by the dam construction.

Lünersee attracts a wide variety of visitors, including families and experienced climbers. Families often choose the circular walking route around the lake, which takes between one and two hours to complete. This trail is mostly gentle and flat, making it accessible to all ages. More seasoned hikers use the lake as a starting point for more challenging climbs, including ascending the Schesaplan summit. The area surrounding the lake is particularly enchanting during June and July when alpine meadows bloom with rhododendrons, edelweiss, gentians, and other mountain flowers, adding to the scenic appeal of the region.

Since 1966, the area between Lünersee and Schesaplan has been designated a protected landscape, contributing to the preservation of the natural values found in this part of the Alps. Despite the crystal-clear waters and abundance of trout, swimming in the lake is strictly prohibited because it serves primarily as an energy storage facility. However, this restriction does not deter the growing number of tourists drawn to Lünersee each year, who come from all over the world to experience its breathtaking scenery and unique charm.
