Donau-Auen National Park

The Donau-Auen National Park is a nature reserve which covers the Danube river as it flows from Austrian capital city Vienna through to the Slovakian border at Hainburg.

The name Donau-Auen literally means ‘the Danube water meadows’ (or floodplains) and aims to protect the unique species of flora and fauna that make their home in this particular landscape.

Much of the Danube river had been altered by flood protection schemes and by power stations and plans to protect the few remaining untouched sections of wetland and floodplain in Austria started back in the 1970s.

History of the Donau-Auen National Park

The Danube was very much a natural river up until the Industrial Revolution in the 19th century. But economic changes meant that the river course was changed to make navigation and trade easier in central Europe and that many of the tributaries were dammed or controlled. Many of the woods which stood on the river banks were also felled over the decades.

The first plans for a nature reserve covering the Danube wetlands and its wildlife were launched in 1973 with work on proposals for a Donau-March-Thaya-Auen National Park. Nearly ten years later the province of Lower Austria declared the region to be a protected landscape and, shortly afterwards, a planned power station at Hainburg met with stiff public resistance and thousands of campaigners occupied the remaining forests.

The opponents of the power station managed to achieve an investigation into the future of the Danube in the area, which led to the official formation of the National Park in 1996.

Protected birds in the National Park include various members of the eagle family, especially the white-tailed eagle, the biggest bird of prey in the region.

Travel to the Donau-Auen National Park

The Donau-Auen National Park probably has the best international connections of any major nature reserve, with Vienna International Airport located just on the borders of the protected area and the main road route between Vienna and Bratislava running along the valley of the Danube.

The southern side of the Danube is also served by the S-Bahn and regional rail services from Vienna through to Hainburg. Several postbus services cover access to the villages and the National Park centre on the northern bank of the Danube.
