Starting south of Vienna near the suburb of Inzersdorf, the Thermenradweg (Spa Cycle Route) is one of the most popular cycle paths in Lower Austria. The 53-kilometre (33 mile) route leads to Katzelsdorf, a municipality near Wiener Neustadt. It offers both enjoyable cycling and plenty of things to discover. On the way, you pass historical towns, experience unique culture through the Vienna Woods, and visit important industrial and historical monuments.
The Thermenradweg is named after the numerous springs found in the region south of Vienna which are fed by the so-called Thermenlinie (thermal fault line). Places like Baden and Bad Vöslau owe their history as spa towns to this geological fault zone. The Romans also appreciated the thermal waters and public spas still operate today such as Römertherme in Baden. As well as sophisticated spas, you also ride along the Wiener Neustädter Canal with its numerous locks and aqueducts that are not only beautiful to cycle through, but also reveal an interesting insight into the era of early industrialisation.
In 2019, some sections of the cycle path were improved and renovated. As the route is well signposted and relatively flat, it’s particularly suited to families and pleasure cyclists. However, the Thermenradweg is also interesting if you want a sporty ride as it guides you in an uncomplicated way out of the suburbs in south Vienna. You can also combine the route with other cycle paths to create a large lap with minimal traffic. For example, you can join the Triestingau Cycle Path from Schönau. The Piestingtal Cycle Path is also easy to reach. The Thermenradweg is also part of the Eurovelo 9 which leads from the Baltic Sea to the Adriatic Sea so you can ride southwards for almost as long as you like.
There’s another reason why this thermal region is so popular – for its wine and culture. On many stretches, the landscape is characterised by wine growing and there are beloved Heurigen, inns where homemade wine is served, in almost every village. An obvious end to your bike Tour is a visit to a cosy Heurigen garden where you can enjoy homemade wines and try hearty local cuisine.
If you end up taking a little longer than expected, you don’t need to worry in most places. The Südbahn train line makes it easy to return to the starting point in Vienna quickly and safely from almost anywhere along the route.
The Thermenradweg begins on the southern edge of Vienna, directly at Vorarlberger Allee. To reach the starting point, the Laxenburg cycle path is ideal, as it brings you here from the city center without stress. After you cross the S1 expressway, you follow a gravel path to Vösendorf, past the castle of the same name and on to Biedermannsdorf. You will pass Laxenburg, whose wonderful castle park is ideal for a detour. Immediately afterwards you cross the Südautobahn to Guntramsdorf on a bicycle bridge. You will reach the Wiener Neustädter Canal, which you will follow from now on, with short interruptions, to the stage destination.
After Guntramsdorf, the many vineyards that thrive on the gentle foothills of the Vienna Woods come into view for the first time. On hot summer days there is a touch of Tuscany in the air. After a few kilometers you will reach the outskirts of Baden. If you have enough time, a trip to the sophisticated city center with the beautifully landscaped spa gardens and many nice cafes is worthwhile. The actual route leads past Baden and immediately afterwards over the Schwechat River. A few kilometers now follow through a beautiful, unspoilt cultural landscape with fields and vineyards. In the west you can see the Hohen Lindkogel and other beautiful Wienerwald elevations.
You now cross the Südautobahn again and you will soon reach the castle park in Kottingbrunn. In the center of this beautiful area there is a moated castle. If you want to visit it, you have to leave the Thermenradweg briefly, but I can also recommend this detour. Alternatively, you can also use the nice break areas directly on the bike path. The route of Eurovelo 9 is engraved in one of the benches - maybe an inspiration for the next tour? Shortly afterwards you come to the intersection of the Wiener Neustädter Canal with the Triesting near Schönau. If you want to take an alternative route back towards Vienna, you can branch off here onto the Triestingau cycle path (Eurovelo 9a).
Only a few kilometers after you have crossed the Triesting, you will cross the river Piesting near Sollenau - beware of confusion. Here the Piestingtal cycle path branches off, which leads into the Gutenstein Alps to Rohr im Gebirge. The following kilometers you drive along a military training area with a beautiful view towards Schneeberg, the easternmost two-thousand-meter peak in the Alps. You will soon reach Wiener Neustadt. The second largest city in Lower Austria is known for its castle, the lively center and the Theresian Military Academy. The bike path also runs along the academy park belonging to the academy.
In theory, you could end the tour in Wiener Neustadt, as the city has a large train station and regular trains run back to Vienna. The official end of the Thermenradweg is a few kilometers further south, just before Kleinwolkersdorf. To reach the place, you follow the Leitha river for a few kilometers. The section is really nice and there is also a good train connection in Kleinwolkersdorf.
