We want to provide you with many moments of pampering and relaxation, which is why we almost always have great special offers and packages so you have even more opportunities to unwind!

Our season tickets: a Multi-admission Card or Wellness Card

If all you want to do is relax to the max and as often as possible, and if you visit Thermen Soesterberg several times a year, month, or even week, then take out one of our attractively priced season tickets! Our Multi-admission Card or Wellness Card is definitely something for you! 

The Multi-admission Card offers you affordable admission prices and nice extras for a fixed number of sauna visits. This ticket is also transferable.

The Wellness Card offers you unlimited access to Thermen Soesterberg on the part of the day for which you buy the card. This card is not transferable, so it's especially for you.


Do you plan to come and enjoy your time with us on a public holiday or other holiday period? Then take a look at the admission prices in the calendar first, as there may be a surcharge on these days. You can see this in the calendar.

If you have a gift voucher, it is sometimes not possible to use this on public and other holidays. This is also in the calendar.

Rental and Purchase

Rather not take your bathrobe and towels back and forth? You can rent them at Thermen Soesterberg! With our towel service, you can also change them several times a day. So you can enjoy dry, fresh towels all day long – bliss!

Forgotten your slippers? No problem. We sell them in various designs and sizes, and maybe even in your favourite colour.

  • Towel service (rental) €8.95
  • Bathrobe (rental) €8.95
  • Bath slippers (purchase) €8.95

Here's another tip: with our Sauna Packet, you can rent a bathrobe, towels, and slippers for €20.95 – that's a 20% saving. Because you buy the slippers, you can take them home.

Swimwear Days

Our saunas are all about feeling good. If you feel even better in swimwear, then come to our Swimwear Days to really relax and enjoy your visit.

From January 8, everyone must wear swimwear every Tuesday. On those days, wearing swimwear is compulsory in all our facilities. Feel welcome and comfortable during the Swimwear Days.

House rules

Relax and enjoy your visit, in your own way. Thermen Soesterberg gives you all the freedom you want. But, of course, that freedom is for everyone. And that's why there are a few rules. Or as we prefer to call them: things to think about.

Guests may not bring their own food and drink, as these cannot be taken into the wellness restaurant. Instead, indulge in some fantastic meals at our restaurants. We can say that in all confidence, because we know what our chefs have in store for you.

Wearing slippers protects you and others. It's obvious (and compulsory!) to wear them in the sauna area, in the showers, and in the restaurant. However, slippers are not allowed in the saunas.

If you want your book, bottle, or glasses always at hand, use our free transparent bags. They're not just convenient, but also sustainable (provided you return the bag when you go home, of course). So you see, we have an eye for you and for the environment.
If you have any electronic equipment, take it with you by all means, but don't use it. Taking pictures is also not done. But that makes sense, doesn't it? If you need to take a look at your mobile phone or watch, this is allowed only in the reception area. Our tip is to keep them at home or in your locker. After all, you come here to forget about time and everyday life.

Most guests come to Thermen Soesterberg for the peace and quiet. It's even compulsory in our resting area, saunas, and steam baths. Guaranteed rest! What could be better? 

Your visit is all about enjoying yourself and sweating, both of which are very healthy. To keep the saunas healthy and fresh, everyone must sit and place their feet on a large dry towel.

Restaurants and wet towels are not a great combination. So when you go for a bite to eat, leave your towel somewhere else. On the other hand, restaurants and bathrobes are a sensible combination. So put on your bathrobe before you sit down to eat.

Of course, intimate conduct is not permitted. We are very clear about this. If you happen to see something that is inappropriate and undesirable, please do not hesitate to report it to us immediately.

At Thermen Soesterberg, we take good care of everyone. We are vigilant, but we cannot see and prevent everything. Thermen Soesterberg is not liable for injury, loss, or theft. Yet if something does go wrong, of course we're there to help you! 

We don't all get enjoyment from the same things, and smoking is one of them. So please use the designated smoking area on the terrace.

Sometimes, our employees give instructions. They do that for a reason, so please do as they say, for your own safety and everyone else's.

Enjoyment doesn't have an age limit, but it does in our wellness resort. Children over the age of 12 are welcome if accompanied by an adult.


We have made a list of frequently asked questions (FAQs).
