Hot spring-fed swimming lakes
Austria’s first thermal water swimming lakes - fed with genuine Gastein thermal water.
Unique, genuine, pure!
As you bathe in these two lakes, all of your senses will feel the power of nature, the clarity of the water and the pure energy that regenerates your body. Unique and genuine, because they are fed with genuine Gastein thermal water. The two lakes, covering an area of 1300 and 370 m², are filled with the treasure of the Hohe Tauern mountains. Every day, 150 m³ of fresh thermal water bubbles into the lakes. Unique and pure, because they are cleaned without the addition of chemical substances such as chlorine. The water is actually kept pure using a biological filtration system. Anyone dealing with skin problems or allergies can enjoy swimming in the lake without giving it a second thought.
Also unique is the setting. Here in the heart of Gastein Valley, with its magnificent mountain views, the outdoor swimming season will extend in future from the beginning of May until late October thanks to the stable temperatures of both these lakes. Kristall See - Sauna World always open (except short revision), Smaragd See - Relax World (in winter time closed). A clear advantage, especially whenever the weather chooses not to cooperate. Plus, if rain and cool temperatures bring a sudden end to your outdoor bathing enjoyment, you can simply move indoors to our welcoming thermal pools and saunas, and make yourself warm & cozy until the sun pops its head out and invites you back outside again.
