Never been to a sauna or only a few times? Then it’s useful to know the unwritten rules.
What you’d better avoid:
In our saunas, everything revolves around peace, respect and relaxation. That’s how everyone feels comfortable.
Thermae Boetfort offers both a swimwear area and a nude area. Your entrance ticket gives you access to both, but you must of course respect the clothing guidelines. For hygienic reasons, clear rules apply:
For a relaxing sauna day, you’ll also need – besides the right swimwear – a bathrobe, two towels and slippers. Don’t have these at home? You can rent them at our reception.
Treat yourself to a moment of peace this summer, you deserve it.
Advance reservations are not possible.
