Petronell - Bad Deutsch-Altenburg - Hainburg - Bratislava
Route description:
You start your tour in Petronell where you follow the main road (Hauptstrasse) eastward until you turn onto Solafeldgasse (road) at the outskirts of town. At the end of that road, you follow the path continuing east until you arrive in Bad Deutsch-Altenburg, the quarry is visible from afar. If time allows, you can get your tired legs back into shape at the local hot springs baths. Bad Deutsch-Altenburg has the strongest iodine-sulfur springs in Europe.
After Bad Deutsch-Altenburg, you head toward the Danube bank and pass under the B49. Shortly thereafter you arrive in Hainburg. There you rest and visit the old, but very well preserved castle. Back on the bike path you say goodbye to the Danube, which you will not see again until Bratislava. You travel along the railroad tracks, then travel a short distance on Thebnerstrasse, taking a left off of this road as soon as possible. You then hit the B9, which has a bike path on its north side. Follow that path.
Just before the border, the road and bike path diverge. After lengthy left and right turns, you ride along the riverbank promenade in Bratislava enjoying views of the Danube, Bratislava Castle and St. Martin's Cathedral as you pedal the last few meters to your destination.
