The park is located adjacent to US-23 about 12.8 miles east of Rogers City and 23 miles north of Alpena, turn onto the marked access road to the park (again, motor vehicle permit required for entry). Go for a half mile, and then turn right and go 0.6 miles to the Trailhead.
From here there are several well marked trails looping out towards Lake Huron.
A June early morning walk is an auditory challenge to the visiting birdwatcher! Good birding habitats include the re-growing clearcut area along the main Trailhead Road, the brushy alder swale where the Grand Lake Outlet crosses Old State Road, and the cattail marsh (where Virginia Rails, Least Bittern and Marsh Wren nest) at the end of Thompson Harbor Road. THSP is a well-known site for the wide variety of wildflowers!
Hunting is allowed in season, so dress appropriately if you are here during October and November.
