In the former gravel pit south of Grenzach-Wyhlen, a diverse habitat consisting of pioneer waters and dry habitats has emerged following the mining. The deepest areas of the pit are in contact with groundwater. This fluctuates accordingly depending on the Rhine and groundwater levels. Already in the accessible part of the nature reserve a rich flora and fauna can be observed. However, reeds and marshes in the eastern part are not accessible to visitors as they are breeding grounds for endangered bird species. Through the rest of the area, a footpath leads past remarkable plant species, such as the marsh horsetail or the Japanese knotweed. In addition to amphibians, numerous dragonflies, water beetles and water bugs also colonize the vegetation-poor areas of the water bodies. Even the banded damselfly, which has become extremely rare in the Basel region, can occasionally be observed here. With a bit of luck, a grass snake can be spotted swimming silently through the ponds. Currently, there are plans to flood the former gravel pit with the Rhine's high water in order to create an artificial Rhine side arm for nature conservation purposes.

The site is not wheelchair or stroller accessible.


Since there are no picnic or barbecue areas in the nature reserve, food must be brought from the backpack. However, there are several restaurants and shopping facilities in Grenzach-Wyhlen and Kaiseraugst.
