Rheinholz Forest Trails

Highlight • Forest

Head to Rheinholz, near Altenrhein, for a peaceful cycling experience where forest trails meet the shores of Lake Constance. Here you’ll find a mix of wooded paths and open views of the lake, making it a great place to cycle or simply relax by the water.

Rhine Delta Nature Reserve

Highlight • Natural Monument

The delta of the Alpine Rhine forms a common delta area with the eastern deltas of Dornbirner Ach and Bregenzer Ach. This delta area extends over the entire valley area (in the shore area from Staad in the west to Bregenz in the east). In the north, naturally the current Bodenseeufer forms the limit, if one disregards the delta continuing under the sea surface. The southward limit depends on the determination of the course of the Bodensee shore after the melting of the Rhine glacier and should be at least a few kilometers. The beginning of the 20th century in the created Rhine trough between Lustenau and Fußach is not an original delta arm and runs in its lower section through the area of ​​the historic Dornbirner Ach delta. Nevertheless, since then the main delta formation has been at the mouth of the Rhine trough between Fußach and Hard, and no longer at the former main mouth of the present Old Rhine. Like the Rhine near Lustenau, the Old Rhine nestles close to the western Rhine valley slope and forms the state border between Austria and Switzerland. The riparian forest on the Austrian side of the Rheinspitz on the old Rhine is called Rheinholz.

The Rhine delta of Lake Constance is the river delta on the southeastern shore of Lake Constance, which the Rhine (also called Alpenrhein) has formed in a former sea area. It lies mostly in the Austrian province of Vorarlberg, smaller areas are in the Swiss canton of St. Gallen. The two peninsulas in the lake are called Rheinspitz (west) and Rohrspitz (east).

Habsburg Bar & Restaurant, Widnau, directly on the Swiss side of the Rhine Cycle Path opposite the customs station. Shouldn't have any days off. Extensive range of snack bars, cheap by Swiss standards. Tasted good.
