Bad Kleinkirchheim's thermal spring

The healing water of the St. Kathrein spring at the Ronacher

Time simply cannot touch some places. They stubbornly resist all the rules of passing time with friendly resolve – radiating energy without losing any of their power. The source of the thermal spring in Bad Kleinkirchheim is such a place. It originates in the crypt below a little church.

The power of St. Kathrein – scientifically proven

Enjoy the effect of the thermal spring in Bad Kleinkirchheim in a variety of ways at Hotel Ronacher. Our St. Kathrein thermal spring's source has a natural temperature of 36 °C and is rich in minerals such as calcium, magnesium, sodium and potassium. Originally famous for healing eye diseases, the indications go way beyond this today.

Stabilising the circulation, strengthening connective tissues and blood vessels, alleviating rheumatic complaints, aiding recovery after operations, accidents and infectious diseases. And very generally strengthening the immune system.

Everything our healing thermal water can do!

Ronacher Spa Manager Mrs. Erika & Mrs. Barbara

"In the crypt of St. Kathrein church I really feel the power of our healing thermal water. I like spending a few minutes here and treat myself to a sip of our healing water. The crypt is a special place of power with tradition, as the fountain of youth has been bubbling away here for a thousand years."
Host Simone Ronacher

"It's a real treat for me to swim in the Ronacher's thermal water, the tension in my back soon vanishes. I recommend all guests try the beneficial healing water in combination with the new "orthomolecular infusion therapies" for instant results."
Spa doctor Dr. Wolfgang Hofmeister

"One real benefit is an eye bath with our healing water. We offer you this treat in the SPA area right next to the thermal water fountain. You will be impressed with how wonderfully your eyes sparkle afterwards."
Qualified cosmetics & beauty expert Erika Mauschitz
