The national park between Vienna and Bratislava starts right next to the Prater Park in Vienna and continues to the border with Slovakia (where the wonderful Devin Castle is located). The park, called Nationalpark Donau-Auen, is an area of wetlands and lakes that are formed each season as a result of parts of it flooding when the Danube River overflows its banks after heavy rains. In fact, it is the largest park in Central Europe that is still partially flooded when the Danube overflows.
If you are planning to cycle from Vienna to Bratislava (highly recommended), you can enjoy the park along your cycling route.
The park contains several interesting historical sites such as the ancient Roman city of Carnuntum and the Eckartsau estate, as well as marked and well-maintained hiking trails and places where swimming or boating is permitted.
Throughout the park, there are about 30 species of mammals, 100 species of birds, 50 species of fish, reptiles, and amphibians. Among the interesting animals in this park are pond turtles, white-tailed eagles, beavers, and more.

Lobau Area
This part of the park is within the city limits of Vienna, so it can be reached quickly and easily from the city center. In this area, there are 3 recommended hiking trails:
The Orange Trail: Upper Lobau
A 5-kilometer trail that takes between two and three hours. The hiking trail starts from the visitor center in Lobau and can be reached by city bus line number 92B (get off at the Raffineriestrasse/Biberhaufenweg stop).
Along the trail, you can see the Dechantlacke, an ancient natural swimming pond, or get a view of the entire area from the Tischwasser observation post.

Along this route, there are several stations related to Napoleon’s army, which fought in this area when it defeated the army of the Holy Roman Empire at the beginning of the 19th century.
