About 80 kilometres north of Vienna on the Czech border, this spa may be well off the beaten path for many visitors, but whether you decide to stay in the on-site hotel or go out for the day by train or car, ThermeLaa is one of the most inviting spas in the area. With both indoor and outdoor thermal baths heated at different temperatures, you can relax in both rain and shine. The sauna area offers several saunas and steam baths, and the themed “Aufgusse” add a touch of class to an already top-notch establishment. After spending time in the saunas, float in the twin-size waterbeds in the relaxation room.
