The Saginaw Bay Visitor Center, located in Bay City State Park on the shores of Saginaw Bay, helps visitors discover Tobico Marsh, one of the largest coastal wetlands on the Great Lakes. 

Nestled under a canopy of sheltering hardwoods on the edge of the marsh, the modern visitor center stands on the site of the historic Jennison Nature Center, built in 1940 and named for George B. Jennison, a prominent local conservationist. In 2023, the aging nature center was given a $2 million makeover. The 10,000-square-foot building, with a 100-seat auditorium, now boasts a fully renovated exhibit area and an experiential classroom.

The Wetlands Wonders Gift Shoppe is located within the center and run by volunteers from the Friends of Bay City State Park. The shop has a wide variety of educational resources for all ages, as well as a large selection of nature-related gifts.
