Located on the Altona flat rock sandstone pavement, Flat Rock State Forest consists of several separate parcels within a rare jack pine sandstone pavement barrens habitat. The largest parcel has multiple-use trails and a snowmobile trail. Much of the property is largely undeveloped and well suited for hiking, hunting and nature viewing.

Flat Rock State Forest features 1.4 miles of forest haul roads as well as 2 miles of snowmobile trails, which are open to other uses. There is an access point and a place to park off of the Military Turnpike. A parking area is also located at the end of Pedobo Road off Rock Road. Although public access is allowed, there are no maintained trails on the smaller parcels of Flat Rock State Forest.
