In Tragoess, Austria, there is a place called Grüner See (Green Lake), one of the most beautiful and unique summer retreats in the world.

In winter, the water level of Grüner See drops almost to nothing, remaining only 1–2 meters deep. Standing on the surrounding green meadows and looking out at the magnificent mountain scenery, lush forests, and crystal-clear lake, you're essentially gazing at a classic European landscape masterpiece — it's a highly popular local park. But as spring turns to early summer and temperatures rise, melting snow from the high peaks gradually flows down the slopes into the mountain basin, slowly submerging the once-exposed park in cool, clear snowmelt, transforming it into the stunning summer beauty of Grüner See.

The most beautiful time for Grüner See is from mid-May to June, when the water depth exceeds ten meters. The clean, clear snowmelt provides excellent visibility, attracting divers from all over who come to explore the underwater remains of the park — every blade of grass, tree, and even features like benches, small bridges, and pathways. These everyday structures submerged in the water create an otherworldly, surreal scene akin to a beautiful painting.

In winter, Grüner See is surrounded by the Hochschwab Mountains and dense forests, with the lake’s captivating emerald-green waters offering another kind of enchanting view that draws many hikers. But summer is when Grüner See is at its most popular — in June, divers and water enthusiasts from all over Europe flock here to explore the snowmelt-submerged park. Through the crystal-clear waters, they enjoy views of distant mountains and the unique experience of “walking” through the park underwater.
