Frequently asked questions
Should I make a reservation with a birthday code?
Did you receive a birthday code in your mailbox? Then you and maximum three friends can come and relax for a day! The birthday girl (or boy) gets a free back, shoulder and neck massage (25 minutes) as a gift, under the condition that he/she takes the entry at 21 euro on the same day. The birthday boy or girl receives an extra gift: a goodie bag with 2 small products of our beauty brand Sirène. Three members of your family or friends can enjoy this special day with you (only the entrance to the thermal baths, not the massage) for the special price of 21 euro per person. Not valid on Friday, Saturday, Sunday and public holidays. Not exchangeable, not renewable or not combinable with other actions. You need to make a reservation by phone in advance, Thermae Boetfort: 02/759.81.96 or Thermae Grimbergen: 02/270.81.96. Simply bring the e-mail with your ID to Thermae Boetfort or Thermae Grimbergen.
