Danube Riverside Promenade, Hainburg

Highlight • River

The Danube near Hainburg is one of the few sections where the river is still free-flowing and natural. We recommend a trip to the Donauauen National Park.

Cave Entrance

Ruins are always worth a visit! It's on the path, so it's not a special detour. The ruins are not particularly large. At the top there is a small viewing area with a bench. Beautiful view of the Danube included.

From here, there is a wonderful view of Hainburg on the Danube and the mighty river that shapes the landscape. The historic old town, the Danube floodplains, and the gentle hills of the surrounding area combine to form a particularly charming panorama.
