Experience Pure Relaxation at GrimmingTherme
GrimmingTherme is located in Bad Mitterndorf, Styria, Austria, drawing its thermal water from a 2,413-meter deep borehole into the Wetterstein limestone of the Grimming massif. The water emerges at 40°C at the well bottom and is classified as an akratische fluoridhaltige Calcium-Magnesium Sulfat-Therme, with a total mineral content of 1,876 mg/L. The architecture follows a modern alpine spa design, with the massive peak of the Grimming mountain serving as the constant visual anchor. Five levels of relaxation space house three indoor and four outdoor pools, all arranged to maximize that mountain panorama.
The signature setup includes separate zones for different needs. The thermal relax area features indoor pools with floor bubble jets, massage nozzles, and whirlpool loungers, plus outdoor pools maintained at 33-34°C. The sauna village operates independently from the bathing area, offering multiple themed saunas, a bio sauna (50-60°C, 50-60% humidity), an infrared cabin (40-45°C), and a dedicated ladies’ sauna area. A cold-water pool at 12-14°C sits ready for the classic Aufguss refresh. The Welldiana Club Spa on the first floor handles massages and cosmetic treatments from 10:00 to 19:00. The wellness philosophy here is straightforward: warm water, heat, and quiet, with no gimmicks distracting from the core thermal experience. Guests come for the reliable 33-34°C pool temperatures, the structured sauna rituals, and the direct view of the Grimming.
This therme works best for adults seeking a calm thermal and sauna day, but it also accommodates families thanks to a separate children’s area with a giant slide, a kids’ pool at 33-34°C, and a youth sports pool at 26-27°C. Plan for a full day: the 4-hour ticket costs €19.50 for adults (therme only, weekday), and the day ticket runs €24.00. If you add sauna access, expect €32.00 for a day pass. The standout feature is the direct connection to the Aldiana Club Salzkammergut, which means you can stay overnight with direct access to the pools and saunas, plus fine dining and winter sports equipment rental on site.
