The Acheneau

Highlight • River

A place on the bridge overlooking the Acheneau river. The river is 30 km long. An interesting point is that this watercourse has such a slight slope that its course can be reversed when sufficiently high tides influence the river level. Human control of this river and the marshes of the southern Loire began especially under the influence and control of the Cistercian monks of the abbey of Buzay from the 12th century.

Window over Lake Grand-Lieu

Highlight • Other

The lake is a natural site and an ornithological reserve and its access is very limited to the public. There are not so many views on this one. You can find them on the lacdegrandlieu.com website

Saint Peter's Church

Highlight • Religious Site

As much as the northern entrance into Port Saint-Père is pretty, with the banks of the Acheneau, the rest of the city and in particular the southern exit towards the ocean, a real nightmare for cyclists, has not left me an unforgettable memory.

Saint-Léger Church

Highlight • Religious Site

Clearly not the most beautiful church in the region, but there are toilets, and therefore water, and bike racks on the square. Thank you to the municipality of Saint-Léger-les-Vignes.
