The Rhine Delta of Lake Constance is the river delta on the southeastern shore of Lake Constance, formed by the Rhine in what was once a lake. It lies largely in the Austrian state of Vorarlberg, with smaller areas in the Swiss canton of St. Gallen. The two peninsulas in the lake are called Rheinspitz and Rohrspitz.

Most of it was created by humans as part of the Rhine regulation, but nature and wildlife have taken over completely, so it was done well.

The Rhine Delta and Lake Constance are one of the most important winter resting areas for thousands of bird species. The favorable climatic conditions and the nutrient-rich shallow water areas allow many bird species to spend the winter and spring here. With a bit of luck you can observe rare species of birds and butterflies. The Rhine Delta is the oldest nature reserve in Vorarlberg; it was placed under protection in 1947. A few years ago it was even included in the list of European protected areas (Natura 2000). Source: https://www.vorarlberg.travel/aktivitaet/lagunen-rundweg-rhein-bodensee/
