Onaway State Park is a public recreation area covering 158 acres (64 ha) on the southeast shore of Black Lake in North Allis Township, Presque Isle County, Michigan.

It contains sand and cobblestone beaches, large rock outcroppings, a campground, and nature trail highlighting a diversity of trees.

In 1921, the state began developing the park, adding two small bathhouses and toilet facilities to the picnic pavilion already in place.

[6] In 1933, the Civilian Conservation Corps (CCC) established a camp at Black Lake, with 15 men assigned to Onaway State Park.

They regraded the entrance road and installed a foot trail, and the next year began excavation of a basement for the already existing pavilion.
