Having a little relax in the Jacuzzi is a must-do during a day of sauna and wellness. All whirlpools, both in the swimwear and nude area, are heated to about 37°C and were custom-made for us. Let the water jets and bubbles embrace your body and enjoy a real hydro-massage!
Where can you find the Jacuzzis?
In the nude area, there is one next to the swimming pool and one inside, next to the steam bath. In the swimwear area, there is a large relaxation pool that is partly inside next to the steam bath and partly outside next to the two swimming pools.
