It’s a great saving for anyone who loves to relax more often, as your total discount can reach €52.50. Our summer pass is flexible and shareable. You can visit any day with this card, and it’s not linked to one person. So you can use it with your partner, your best friend, … and it doesn’t have to be the same person each time. You decide how you use the 5 entries.
Guests visiting with a summer pass also receive 10% discount on massages and treatments. It’s the perfect way to make your wellness day even more complete. Our summer pass is available from 15 June exclusively at the reception of Thermae Grimbergen. That way, you’re immediately ready to enjoy your first visit. The 5 entries must be used before 18 September 2026.
