Wellness with a view

After an active day in the mountains or simply because a break does you good: in our rooftop infinity pool and Relax.Spa you will find your personal place to switch off. Swim with a view of the peaks, feel the soothing warmth of our saunas or retreat to our loungers. 

Between warm water, gentle heat and invigorating freshness is created precisely the kind of relaxation you need right now. Completely without rush and always accompanied by the mountain world of the Kleinwalsertal. 

Rooftop Infinity Pool - Dive in above the rooftops

As the first rooftop infinity pool in Kleinwalsertal, you float between the sky and the mountains, with views of the peaks, expanses and clouds. Every dip in the water gives you peace and quiet, every moment in the warm pool makes everyday life recede into the distance.
With a length of 10 metres, a width of 4 metres and a depth of 1.35 metres, it offers enough space for swimming and floating. The water temperature is between 28 and 30 °C - a pleasantly refreshing 24 °C in summer.
Whether in the morning, when the first rays of sunshine gild the mountains, or in the evening, when the lights sparkle in the valley - the rooftop infinity pool is your place for relaxation with a view. Warm, calm, sublime - and simply incomparable.

Opening hours:
Summer 07:00 – 20:00
Winter 08:00 – 10:00 & 15:00 – 18:00

Sauna world with variety

Vigorous, gentle or tailored to your needs: in our Relax.Spa you decide which warmth is right for you today. The Finnish sauna provides a soothing sweat at 80°C, while the bio sauna offers a milder sauna experience at up to 60°C. 

A special highlight is the combination sauna, where the temperature and humidity can be regulated entirely according to your preference. And IIn a steam bath, pleasant warmth meets high humidity. After that, it is all about taking a deep breath and savouring the feeling.

Opening hours:
Summer 15:00 – 20:00
Winter 14:00 – 20:00

Soothing regeneration

Sometimes the best rest lies in a change. Our marble heated loungers provide you with soothing deep heat for greater vitality and well-being, and allow strained muscles to relax. Wellness showers and Kneipp pools also provide a refreshing stimulus and get your circulation going again. 

Afterwards, everything can take effect: on our loungers you will find a cosy retreat for reading, dozing and simply doing nothing. This is how your own rhythm of warmth, cooling down and soothing peace is created.
