Marais de Saint-Hilaire-Arçais

The Marais de Saint-Hilaire-Arçais is a wetland in the Poitou region with a network of canals and waterways spanning across 2,500 hectares. The landscape features varied plant life and supports water birds that move through the quiet waters and marshy areas.

Medieval farmers developed this section of the Marais Poitevin by digging ditches and building levees for farming purposes. These human changes shaped the natural landscape over many centuries.

Local residents grow vegetables in traditional garden plots using methods handed down through generations. These gardening practices shape how the place looks and reveals a way of life adapted to living among waterways.

The area can be explored from La Roche starting point with marked trails and boat rental options, plus bicycle paths throughout. Wear appropriate clothing and sturdy shoes since the ground is wet and can be slippery in places.

A former tile factory that operated until the 1980s left behind clay holes in the marsh that became their own ecological micro-habitats. These human-made ponds now support specialized plant and animal communities that exist nowhere else.
