Phew, you made it, summer is finally here! With its slower pace of life, this is the perfect season to carve out some me-time. Don’t envy the many holidaymakers jetting off to faraway places. Often, things are more peaceful, quieter closer to home at this time of year. And you know what that means – time for a wellness day!
Rest assured, we are not going anywhere. Our doors are wide open, all summer long, seven days a week. And yes, you can even visit us on public holidays like 11 July (Day of the Flemish Community), 21 July (National Day of Belgium) and 15 August (Assumption of Mary). So, whether you want to have a relaxing sauna day, a pampering treatment or go all out with a mini-break with overnight stay; take your pick, we are ready to give you a warm welcome!
Sauna and summer ... Uh, really? Yep! It may seem counterintuitive, but once you try it, you will definitely come back for more. Thanks to the heat of the sauna, your body is stimulated to cool down better and you can really feel this.
With refreshing showers, plunge pools and cosy outdoor terraces, your summer wellness day will be perfectly balanced.
Time off during the summer public holiday(s)? This is the perfect excuse to press the pause button. Instead of throwing yourself into the crazy busyness of those days, come and soak up the heat, relaxation and tranquil atmosphere at our centre.
Whether you are visiting us solo, with your partner or a good friend, just choose the wellness experience(s) you fancy. You could start your day in our saunas and end the evening with an overnight stay at our hotel. That’s how you turn a day off into a real mini-break!
Ready for a relaxing break in the middle of summer? Plan your wellness day today and immerse yourself in a peaceful, calming experience.
