Sole Uno is the name of thermal baths located in Switzerland, more precisely in Rheinfelden, very close to Basel. It is really easy to get there from Alsace.

The thermal water directly comes through a pipeline from the Saline Rheinfleden-Riburg. It is known for providing numerous benefits to the skin, muscles, joints, blood circulation and so on…

The place is very pleasant. It includes bathing facilities (bathing suit is mandatory), sauna facilities (it is naturist, wearing a bathing suit is forbidden) and a massage lounge. I, for one, stayed in the bathing facilities, where there was already a lot to do. At Sole Uno, you will find indoor and outdoor pools with jets, a salt water pool where you float while listening to underwater music, hot and cold water baths, aromatic steam baths with different flagrance, tropical and alpine showers and finally a salt inhalation grotto. Definitely enough things to try out to have a lovely time!

I liked

  • The variety of baths available
  • The ideal water temperature in large pools
  • It’s open every day until 10.30 pm. It’s very pleasant to spend an evening there.

I liked a little less

  • It’s more expensive than thermal baths in Germany, but that’s how Switzerland is!
  • Parking is not free


It is forbidden to take pictures, so I invite you to have a look at the website Sole Uno in Rheinfelden.
