hot springs
There are many hot springs in southern Burgenland and south-eastern Styria, so watch out that you don't fall into one of the many thermal basins if you don't watch your step. The water for the thermae comes right out of the earth, heated by volcanic activity and is mostly around 36°C, enriched with minerals and very nice to relax in. There will also be offered common wellness services such as solarium, massages, drinks, mudbaths, sauna and others. Often enough there are opportunities to play golf, do horseriding, go bicycling or hiking, do sports and such.
The Village you find the thermae in will contain a lot of expensive hotels and cheap hostels to spend your time. You should not think about staying outside the actual thermae village, because stretches of way between villages are rather long in Burgenland, and the public transportation infrastructure is, to say the least, poor.
Thermae in Burgenland with their primary targets are:
Bad Tatzmannsdorf (http://www.burgenlandther...) A village more for elderly people mostly on rehab
Stegersbach (http://www.dietherme.com/) For families with children, with golf links
Lutzmannsburg (http://www.sonnentherme.com/)
Not in Burgenland, but in the area:
Loipersdorf (http://www.tiscover.at/lo...) Very nice for kids, with golf links
