SRDC and Patriot Harbor Lines are partnering to provide riverboat tours of the tidal river. Tours are scheduled for select Thursdays and Sundays starting on May 9th (Mother’s Day). The full schedule and ticket prices can be viewed here. Riverboat tours leave from and return to the Walnut Street Dock, which is located under the Walnut Street Bridge. Tours are one hour long and narrated, so participants will learn about the river and buildings along the riverbank during the tour.
