The renaturation of the Danube near Hainburg, particularly in the Johler Arm area, is one of the most important ecological projects in the Austrian Danube region. The goal was to return the heavily regulated Danube to its natural state and to restore valuable floodplain forest and river habitats. The Johler Arm, a former branch of the Danube near Hainburg, was reconnected to the main stream as part of the project. This reconnection ensures regular water flow through the branch, restoring dynamic river processes such as flooding, sediment relocation, and natural bank formation. As a result, many rare animal and plant species – including fish, amphibians, and waterfowl – benefit from new habitats. The project also improves ecological continuity for migratory aquatic organisms. A landscape-enhanced floodplain landscape was created along the Danube, where the natural diversity of the Danube can once again be seen and experienced – a successful example of near-natural watercourse development in the Danube Floodplains National Park.

Baroque Garden - The Garden Paradise, Hof Castle The area sloping down to the March lowlands to the east of the castle was predestined to create a garden based on the French model simply because of its location. In just a few years, Prince Eugene had the architect Johann Lucas von Hildebrandt and the garden engineer Anton Zinner create one of the most important gardens in the German-speaking world on a total of seven terraces. The vertical central axis, along which there are numerous fountains, divides the garden into two mirror-image areas on each level. A well-thought-out sculpture program created by the sculptor Johann Christoph Mader pays homage to the lord of the castle, Prince Eugene. The water required to operate the fountains and to supply the plants was derived from three ponds in the nearest village of Groißenbrunn. In the 19th and 20th centuries, the garden gradually fell into disrepair. The three paintings by Bernardo Belotto, known as Canaletto, were one of the most important sources for the gradual reconstruction of the individual terrace areas since 2002. These views of the palace complex were created on Maria Theresa's commission around 1760. Text / Source: Schloss Hof, 2294 Schloßhof 1 https://www.schlosshof.at/ueber-schloss-hof/garten

A river and forest setting that pleases. In Italy similar settings are found only in high mountain landscapes. Handsome.

The Marchegg area is renowned for the expansive floodplains of the March River, forming the significant Untere Marchauen nature reserve. This region boasts ancient alluvial forests, diverse riverine environments, and is a crucial habitat for numerous species. You can also experience the natural jungle-like environment along the Danube at the Hainburger Au Trail.
The Marchauen Nature Reserve is a haven for wildlife. It hosts the largest tree-nesting white stork colony in Central Europe, with up to 40-50 active nests from late March to mid-August. Beyond storks, you might spot beavers, kingfishers, fire-bellied toads, and even herds of Konik horses. The area is also home to various bird species like the black stork, grey heron, and white-tailed eagle. At the Danube River Restoration site, with a bit of luck, you can also see kingfishers and beavers.
The best time to visit the Marchauen Nature Reserve to observe the white storks is from late March to mid-August, when they are nesting and raising their offspring. Generally, spring and summer offer the most vibrant natural experiences with lush landscapes and active wildlife. Autumn provides beautiful foliage, while winter offers a different, quieter perspective, though some facilities might have reduced hours.
Yes, several natural monuments are suitable for families. The Weikendorfer Remise Nature Reserve offers forest landscapes ideal for nature observation. The Hainburger Au Trail provides a scenic and cooling experience on hot days, perfect for families.

You can find more details and routes in the Hiking around Marchegg guide.
While primarily natural, some sites offer a blend of history and nature. Devín Castle, though a historical site, is considered a natural monument due to its strategic location and scenic views of the confluence of the Morava and Danube rivers. It was an important historical crossroads used by Romans. The Baroque Garden of Schloss Hof is another example, a meticulously restored 18th-century garden that is a man-made monument within a natural setting.
While specific rules can vary by exact location within the broader Marchauen area, generally, dogs are often permitted on trails in natural areas if kept on a leash. However, it's always recommended to check local signage or specific reserve guidelines, especially in sensitive wildlife breeding areas like parts of the Marchauen Nature Reserve, to ensure compliance and minimize disturbance to wildlife.
The Marchauen Nature Reserve features well-maintained visitor trails and observation platforms designed to allow close-up views of flora and fauna. While many paths are natural, some areas, particularly around visitor centers like the Storchenhaus Marchegg, may offer more accessible routes. For specific accessibility information, it's advisable to contact the visitor information center directly.
Beyond hiking, the region offers excellent opportunities for cycling. You can explore various MTB trails, such as the 'Devín Castle – Devín Castle Ruins loop' (14.1 km, easy) or the 'Marchegg Lake – Border bridge over the Morava loop' (40.8 km, moderate). Gravel biking is also popular, with routes like the 'March Gate, Schloss Hof – Schloss Hof Palace and Gardens loop' (34.5 km, easy). More options can be found in the MTB Trails around Marchegg guide and the Gravel biking around Marchegg guide.
Marchegg is generally accessible by public transport, particularly to the town center and Marchegg Castle, which is adjacent to the Marchauen Nature Reserve. From there, many natural areas are within walking or cycling distance. For specific routes and schedules to individual natural monuments, it's best to consult local public transport information.
Visitors particularly appreciate the unique opportunity to observe the large white stork colony in its natural breeding environment within the Marchauen.
