Sand Docks area is just south of the main channel to Lake Michigan
There is a marina, Harbor Towne, right in the middle of it.
There are wooden pilings still visible from were the ships that hauled the sand away docked for loading
The Harbor Towne development used to be Pigeon Hill, one of the highest elevations in the lower peninsula
Take Laketon all the way out to the bea h and follow the road along the channlel.
At the end will be a parking area.
Short walk out the perch
Hope this helps
Good luck.
