Escape the winter rush at Thermae Grimbergen
Warmth and relaxation at our green wellness oasis
The days are getting shorter, while diaries are filling up fast. That’s exactly why taking a break from your seasonal engagements does wonders for body and mind. At Thermae Grimbergen, you can leave the winter busyness behind and swap it for warmth, wellness and me-time.

What pampering formula will you pick to spend your winter’s day?
A sauna day is a wonderful experience in itself but adding a relaxing treatment turns your me-time moment into a real wellness treat. Here are our three tips.
The Full Body Bliss formula combines a whole day’s entry to our sauna and wellness facilities with an 80-minute Full Body Massage. That gives you plenty of time to explore all our facilities and let yourself be pampered from head to toe.
Want to spend more time in the saunas and less time having a pampering treatment? Our Head & Back Release package includes a whole day’s entry to the public baths and a 25-minute back and head massage for a little extra wellness enjoyment.
Or maybe you are looking for something a bit different? Our Head & Hair Detox: Head Spa Wellness package is the one for you. This combines a one-day entry to our public baths with a 50-minute conditioning ritual for your scalp and hair. A unique way to relax that originates from Japan.
A sauna day during the Christmas holidays
