The park, approximately 6.1 acres (2.5 ha), is located along the east bank of the Saginaw River in Bay City, Michigan, United States and centered on an amphitheatre.

Wenonah Park was established in 1908[1] as a part of the construction of the adjacent Wenonah Hotel (the site is now occupied by a DoubleTree by Hilton), giving the hotel a clear view of the riverfront.

Full development of the park and construction of the auditorium began after the hotel opening.

It was contingent upon the citizens of Bay City approving US$200,000 (equivalent to $6,782,222 in 2023) in bonds for the purchase of two blocks along the Saginaw River, the removal of buildings, and conversion of the sites into a public park.
