Danube-Auen National Park is one of Europe’s last remaining large-scale floodplain ecosystems — a 9,300-hectare protected natural paradise of meandering river channels, old-growth riparian forest, and vast water meadows stretching along the Danube between Vienna and Bratislava. One of Austria’s six national parks and part of the transboundary Ramsar wetland complex shared with Slovakia, the Donau-Auen offers a remarkable wild refuge within sight of two capital cities — a biodiversity hotspot where beavers, white-tailed eagles, and the endangered European pond turtle thrive.

Exploring the Last Wild Danube
The Danube here flows unconstrained — a rarity for a river that has been heavily regulated along most of its European course. The park protects one of the last free-flowing sections of the Upper Danube, where seasonal floods reshape the landscape annually, creating a dynamic mosaic of water channels, gravel banks, softwood and hardwood forests, and open meadows.
The park is home to over 800 species of vascular plants, more than 30 mammal species (including beaver, otter, and wild boar), and over 100 breeding bird species. The return of the white-tailed eagle — Europe’s largest eagle — as a breeding species is one of the park’s great conservation success stories.
Exploring by bicycle or canoe is the best way to experience the park. The Danube Cycle Path runs through the northern edge of the park, and rental canoes are available for guided paddles through the silent side channels where kingfishers dart and dragonflies shimmer above the water.
The Danube-Auen National Park or Nationalpark Donau-Auen in German covers 93km2 and it is situated between the European capitals Vienna and Bratislava and is one of the largest remaining floodplains of the Danube in Central Europe.
Danube is still free flowing here and is the lifeline of the National Park. It creates a habitat for a number of animals and plants, some of which are rare species. Accompanied on guided walking tours or on boats, visitors have ample opportunity to get to know the fascinating world of the “Donau-Auen”, the Danube wetlands.
Donau-Auen National Park was established in 1996 and in 1977 the Lobau region was declared a preserved area by the Austrian government, as well as by UNESCO.
It is good alternate at your visit to Wienna.
