Mary Jane Thurston State Park's day-use parking area provides access to the Maumee River via a boat launch ramp and marina with seasonal kayak rentals.

The parking area is located at the end of the drive from State Route 65 and offers convenient access for paddlers and boaters, though note that portaging around the dam is required.

Amenities include restrooms, picnic areas, and a 96-slip marina with dock rentals available on a daily basis.
