Very good spot on the left bank to admire the plain of Mazerolles, this vast body of water on the Erdre, 1 kilometer wide by 3 kilometers long, which is more reminiscent of a lake than a river. The path that runs through the site is frankly pleasant, apparently popular with local joggers. Picnic tables.
