Sleeping Bear Dunes Naional Lakeshore has a number of SOTA summits - Shauger Hill might be considered to be in the heart of the Lakeshore. Note That the official NPS map shows "Shauger Hill" (E on the map) quite a distance from the USGS coordinates used by SOTA.
Take M-109 off of M-22 and check in at the entrance station - this is a fee park. I recommend getting a copy of the Lakeshore map to follow the one-way Pierce Stocking Scenic Drive and the numbered features.
