Between the river and the Bugey mountains, these ancient meanders are the fruit of the wanderings of the Rhône, which passed through there several centuries ago. When it receded, the waters were gradually covered by sediments, then by peat, giving way to marshy meadows and humid forests along the river, over nearly 90 hectares.
There are more than 300 floral species including 30 remarkable species as well as 15 remarkable animal species.
All these marvelous aspects are to be discovered along an educational trail, on foot or by bike. Explanatory panels and stations extend over the 3 km loop, between marshes, alluvial forest and glimpses of the river...
