Thermen Maarssen, pleased to meet you!

New name, familiar serenity and relaxation.
Peace, relaxation, and serene wellness – you’ll find it here in Maarssen. And if you previously found your way to SpaSereen Maarssen, we’ll welcome you from March 5 – at that same waterside location – as Thermen Maarssen. The name is new; the place, serenity, and wellness remain wonderfully the same.

What also won’t change for you are any existing reservations and the validity of active bathing passes and gift cards. If you have made a reservation through SpaSereen, it will remain in place. If you have a SpaSereen bathing pass, you can continue to use it within its stated validity period. Gift cards will also remain valid until the expiration date indicated on them.

With a new name and a new logo also comes a fresh website. From now on, you can make reservations and book packages more easily and quickly. Want to reserve even more easily and quickly? Then use the Thermen Resorts App and create your own account.

Also discover the Thermen Fans program, where you receive personal benefits with every visit toward your next day of relaxation.

Will you soon be coming to unwind and enjoy yourself at Thermen Maarssen?

We look forward to welcoming you!
