Island Park 
Previously called Sportsman Island, and Oxbow Lake, the city-managed island houses 17 acres of varied and distinct ecosystems as well as extensive trail systems. Meadows, oak grove, pine forest, and cedar marsh areas radiate with beauty and wildlife. Hike through the woodlands, or travel the gentle sloping trails along the 4,400 feet of Thunder Bay River shoreline. With a variety of ecosystems, no two paths are alike. There are several fishing platforms and a lookout area that is handicap accessible.

Island Park is located on the Thunder Bay River, at the corner of US-23 and Long Rapids Road. Access to the island is gained by way of a beautifully hand-hewn covered wooden bridge, created by Michael Kendziorski. The bridge and the island are closed to vehicles. (Please contact the city if additional access is needed to reach the handicapped accessible viewing area). Visitors are encouraged to remain on the trails to help preserve the fragile ecosystems of the island. Please, “Take only pictures, and leave only footprints.”

Duck Park
Duck Park offers fishing and a picnic area and provides a great vantage point for viewing a large variety of bird species in the sanctuary area. Kayak and Canoe rentals are available seasonally.

Within the city limits of Alpena in an oxbow of the Thunder River, there is a wildfowl sanctuary, located north of M-32 (Washington Avenue) and west of US-23 (Chisholm Street). The Alpena County Fairgrounds, at the intersection of 11th Avenue and Fair Avenue, provides excellent views of this sanctuary. The sanctuary can also be viewed from Island Park, located just west of the intersection of Long Rapids Road and US-23 (Chisholm Street). A footpath circles the island with good views of the river and marshes.
