Wellness looks back on longstanding tradition in Rheinfelden. In fact, this delightful resort strongly influencing bathing tourism was founded as early as 1866. It made sense then, and still does, to make good use of the unique treasure of natural brine. Retrieved from 200-meter depths, it counts as one of the most concentrated brines in the world. For relaxing and health promoting bathing pleasures, the brine is mixed with Rheinfelden water - which is extraordinarily rich in mineral content, and then warmed to temperatures between 33 and 36 degrees. The “sole uno“ wellness baths of Parkresort Rheinfelden propose a trip round the world; from sauna culture such as that of Finland and Siberia, a dive into Mediterranean like ambiance for an enjoyable swim, followed by floating in the uniquely salty waters of an intensive brine bath, reminiscent of the Dead Sea. Hotel EDEN im Park also bids guests a sophisticated spa landscape as well as pampering treatments. But wellbeing is not only limited to poolside waters, and leisure offers are close to nature and abundant in Rheinfelden. Stroll through the car-free historic old town, enjoy the boutiques and cafes of the famous Marktgasse, walk the Fricktal highland trail, visit the Feldschlösschen brewery or explore the Roman city of Augusta Raurica. In the oldest Zähringer town in Switzerland there are plenty of pleasurable activities to immerse in - in addition to salty water!
