Thermae Grimbergen is a green wellness estate north of Brussels run by the same group as Boetfort, with its thermal areas split between Aquarius, the nude section, and Sabai, where a swimsuit is worn. Two private saunas, Cleopatra and Yasmine, can be hired separately. The weekly experience programme includes Mindful Moments on Wednesdays and Cold Awareness on Thursdays. The baths open daily from 10:30 to 23:00 and a physical ID card is required at the door.
