Hudson’s St. Croix RiverFest is an annual community celebration in mid-July. This event includes a wide range of activities designed to allow people of all ages to actively enjoy the Lower St. Croix River and all that it provides. Several local organizations and individuals have collaborated to make “RiverFest: A Party with a Purpose” a success. The six-day event celebrates the river while also recognizing the need to preserve its health and beauty.
