Obviously, we have a wide range of wellness experiences and facilities at our wellness centre that will keep you entertained for days, with various saunas and wellness baths for you to explore. These are spread across two separate areas: a swimwear area for guests who prefer their wellness in swimwear, and a nude area, for guests who like having saunas in the nude. Thanks to our generous opening hours, you will also have plenty of time to take a look around the local area. You could go to Humbeek, for instance, where you can follow the Hoge Horik walking route. This takes you past Lintkasteel, a former moated castle, through the Lintbos woods and along the Brussels-Scheldt sea canal.
Hoge Horik walk – 8.5km – starts at Saint Rumoldus church – follow these walking route junctions: 638 – 637 – 636 – 604 – 603 – 633 – 634 – 640 – 641 – 642 – 638.
Did you know that there are lots of other walks, cycling routes and places of interest in the local area? Find out more on our blog.
