Do not follow the google maps or GPS directions, they will lead you the wrong way (onto private property). Access Alger Island campground via Petrie Road. There are signs for the campground on South Shore Road, follow them carefully. This camp site is water access only, there are many boat rentals in the area, but I do not believe the campground itself rents boats. Had a great time! brought our own canoe, no potable water on the island itself.
