The incredibly relaxing saltwater pool at Sole Uno mimics the sensation of floating in the Dead Sea, with the adding advantage of soft music that's audible underwater. About 20 minutes outside of Basel, Rheinfelden became known as a healing haven after natural salt deposits were discovered here in the late 19th century. Wellness seekers still come for the soothing waters, which they can enjoy in peaceful surroundings at the all-season outdoor pool that spirals into a bubbling whirlpool. The sprawling facility includes Finish-style saunas, an authentic Russian banya, and several steam baths. To get here by car, take A3 toward Zurich, then get off at the Rheinfelden East exit.
