Onaway State Park is located in the northern part of Michigan's lower peninsula, and is a popular destination for outdoor recreation enthusiasts. The park offers a variety of activities, including camping, fishing, boating, swimming, hiking, and wildlife viewing.

One of the main attractions of Onaway State Park is its location on Black Lake, which is known for its excellent fishing. Visitors can fish for walleye, pike, bass, and other species, both from the shore and from boats. The park also has a swimming beach, boat launch, and several hiking trails that offer scenic views of the lake and surrounding forest.

In addition to its natural beauty, Onaway State Park is home to several historic sites. One of the most notable is the Tower of the Winds, an observation tower that was built in the 1930s as part of a depression-era public works project. The tower offers panoramic views of the park and surrounding area.

Onaway State Park also has a rich cultural history, with evidence of Native American habitation dating back thousands of years. Visitors can explore the park's history and culture at the Onaway Area Historical Museum, which is located nearby.

The best time to visit Onaway State Park depends on the activities you are interested in. Summer is the most popular time, with warm weather and plenty of opportunities for swimming, boating, and hiking. Fall is a great time to visit for fishing and leaf-peeping, as the trees in the park and surrounding area turn brilliant shades of red, orange, and yellow. Winter offers opportunities for snowmobiling and ice fishing, while spring brings wildflowers and migratory birds to the park.
