Forest Nature Area is a unique park property— you may have visited without realizing it was city property, or you might not realize that it even exists! Forest is connected to Parker Mill County Park and only accessible by walking through Parker Mill. Both Forest and Parker Mill are managed by the Washtenaw County Department of Parks and Recreation. Forest is a 17-acre woodland and wetland along the Huron River and Fleming Creek​. View the Ann Arbor Parks and Nature Areas map for location context. Fleming Creek flows through the park with a boardwalk following its course. During your walk, you will visit a forest community that has a rich layer of woodland wildflowers. The Hoyt G. Post Trail memorial boardwalk trail leads the hiker through an excellent example of a wet forest including black maple, hackberry and rock elm and has interpretative signs throughout. A historic mill and other buildings are located at the northwest end of Parker Mill.​​ Forest is one of the few Ann Arbor park locations that has hosted the Prothonotary Warbler, which is a sp​ecies of special concern.

Access and Parking

Forest Nature Area can only be accessed by walking through Parker Mill County Park​. Forest is accessed by walking on the Hoyt G. Post Trail— the trail enters​ Forest when it goes underneath the railroad bridge. The park is sometimes inaccessible in the spring when water levels are high.

There is a parking lot for Parker Mill off of Geddes Rd. It takes about 10 minutes to walk from the Parker Mill entrance to get to Forest.​

Parker Mill connects to Gallup Park and the B2B Trail​ to the west via a paved path, which walkers and bicyclists can use to get to the park. There are bike racks in Parker Mill. Bicycles are not allowed on the trail in Forest.
