Sole Uno is the name of the spa in Rheinfelden, Switzerland, just outside Basel. It's very easy to get there from Alsace, and it's a place I really enjoyed!
My summary
I liked
- The variety of baths offered
- The water temperature in the large pools is just right
- Open every day until 22:30. It is pleasant to spend an evening there.
I liked less
- More expensive than the thermal baths in Germany but it’s Switzerland!
- Paid parking
Thermal spring water
The name “Sole Uno” refers to the salt water (“sole” in German), which is the central element of these thermal baths. The salt-rich thermal water comes directly from the local saltworks (the Rheinfleden-Riburg saltworks) via pipeline! It is reputed to offer numerous benefits for the skin, muscles, joints and blood circulation…
