Did you know that there is a very large natural swimming lake at Thermae Grimbergen?
Read the entire article
A few years ago, our wellness estate was extended with a huge garden, where you can now also find several saunas, a relaxation area, a salt room, a lovely bar and a very large natural swimming lake.
The swimming lake is continuously filtered, so you are swimming in clean water. There are two different 100% natural filter systems and no chemicals are added to the lake. In the summer, it’s the perfect place for a refreshing dip, and in the winter, you can cool down in the lake after an Aufguss session in the Kelo sauna. In sunny weather, sun loungers are set out by the swimming lake so that you can soak up some rays by the lake. Don’t forget your sunscreen!
Next time you visit Thermae Grimbergen, make sure you explore the garden. Have a relaxing stroll and maybe even a refreshing dip in the swimming lake. Feel all your stress just melt away.
