Data & Figures

Riverine Wetlands National Park, Category II, recognized by the IUCN. Total area currently over 9,600 hectares; of these, approx. 65% is riparian forest, 15% meadow, and approx. 20% is covered by water. Expansion of area is planned.


With over 9,600 hectares area, the Donau-Auen National Park protects the last remaining major wetland environment in Central Europe. For a distance of just over 36 km, the Danube flows freely and is the lifeline of the national park. The dynamic rise and fall of water levels - sometimes up to 7 meters - mean that the wetlands landscape is constantly recreated and reformed. In this way, the flow of the Danube creates habitats for a large number of plants and animals.

With the founding of the Donau-Auen National Park in 1996, this area was made an international refuge for posterity. Here, an ecosystem can blossom free of commercial constraints, thus guaranteeing that future generations may also experience first hand its power and beauty.

The Donau-Auen National Park extends from Vienna all the way to the mouth of the March River (also called Morava) on the border to Slovakia. Thirty-eight kilometres long, at its widest point the Danube measures only around 4 km; the wetlands are only found directly on the Danube. To the north of the national park are the broad plains of the Marchfeld. To the south, the boundary is formed by the breakline of the Vienna Basin. The Lobau area has always been a popular recreational area, especially for the Viennese.

The Lobau area has always been a popular recreational area, especially for the Viennese. Running through the national park are both the long-distance rambling trail 07 and the Danube Cycling Path, which comes from Passau and continues to Hungary via Hainburg.

The protected area can be freely visited for walking, hiking, cycling etc., no entrance fee is charged. However, the rules of conduct must be observed: Hiking trails may not be left, there are some routes approved for cycling, as well as waters that may be navigated by non-motorised boats.

A wide-ranging visitor programme with guided hikes, canoe and rubber dinghy tours, events, etc. also offers many opportunities to explore the national park in the company of national park rangers for a fee and to learn interesting facts.

Tasks and Aims

Extracts from the agreement according to Article 15a of the federal constitution ("National Park Law")

  • Work in accordance with the IUCN criteria in consideration of acceptance by the general population

  • Advancement and maintenance of this area as a gem of nature and one of both national and international importance

  • Preservation of the representative landscapes of the area as well as wildlife and plant ecosystems, including their respective habitats

  • Utilisation of the opportunities for using the area for the purpose of education, recreation, science and research

  • Safeguarding of groundwater levels in the Danube wetlands

According to international criteria, a national park serves to:

  • Protect the ecological integrity of one or more ecosystems for future generations

  • Exclude exploitation or occupation inimical to the purposes of designation of the area

  • Provide a foundation for spiritual, scientific, educational, recreational, and visitor opportunities, all of which must be environmentally and culturally compatible
