The nutrient-rich stagnant waters of Bienener Althrein are characterised by extensive zones of floating leaves and reeds, and small areas of floodplain forest are found along the banks. The area is characteristic of the breeding birds of the Lower Rhine, as was the case for several decades. In addition to a large number of breeding birds, the nature reserve also offers many resting limicoles and, in winter, huge groups of geese and white-tailed eagle.
Parking is available in the adjacent village Rees-Bienen. The area itself can be reached via a dyke, which is designed for pedestrians and cyclists. The dyke also offers the best view of the area.

In the nature reserve, the only Black Tern colony in Northwest-Germany breeds on artificial nesting aids. The Black Tern had also disappeared at the beginning of the 1990s in the Bienener Altrhein. With the help of a species protection project, the Naturschutzzentrum im Kreis Kleve e.V. has succeeded in reintroducing this endangered species.
There is probably no need to mention that exemplary behaviour is required. In this way, the breeding birds, but also the residents should not be disturbed.
Many of the surrounding green areas and waters are recommendable.
