Thermae Grimbergen

A large sauna complex just north of Brussels with two separate zones: Aquarius, where bathing is nude, and Sabai, where swimwear is worn. Regular Aufguss sessions, a restaurant and bar make it a full-day outing. Bring a physical ID card, as entry is refused without one.

Good to know

• Nude bathing is allowed or expected – check the venue's rules for mixed areas.
• There's a restaurant on site, so you can make an afternoon or evening of it.
