Since 1989, the Société d'aménagement de la baie Lavallière has worked to preserve and promote the marshes and swamps of Baie de Lavallière. By taking a path through the wetlands, visitors can observe a great variety of flora and fauna, including some rare species.

With a surface area of 21 km2, Baie de Lavallière is the largest managed marsh in eastern North America.
This fish ladder was installed to allow late-spawning species, such as Largemouth Bass, to enter Baie de Lavallière from the Yamaska River when water levels are low.
The wetlands of Baie de Lavallière are a great place for birdwatching.
