Located west of the town of Petit-Mars, the Port de la Rivière is one of the few public spaces in the town providing access to the Erdre River. About fifteen boats and rowboats moor there year-round. A protected natural area, its banks are accessible on foot. A footbridge allows you to cross one of the branches of the "most beautiful river in France" to continue your stroll closer to the water. Picnic tables are set up there to make the most of this bucolic spot, which welcomes visitors every year at the end of August. https://www.petitmars.fr/decouvrir-petit-mars/tourisme/visite-guidee

What we'd heard about Brittany was that it's supposed to have lots of forests, a special kind of people, and nature beyond nature. But we weren't expecting such a beautiful little town, and as for the special Bretons – they're just super friendly!
