I camped in the area around the falls as a kid, and have fond memories of it. Nothing prepared me for camping near the river mouth. You want the old part of the campground, right on the river, with no electricity. The sunsets are magical, and are happening right in front of you. Simply the best experience short of backpacking. It is a short walk to the newer part of the campground where there are flush toilets. That just keeps everything in the old part very quiet.
I tent camped here with my parents, and came back often with my own children. Far enough from Mackinaw City for peace and quiet, near enough to visit all the attractions during the day. Tall trees and a beautiful beach. It,s a great vacation destination. One of the best state park campgrounds in a state full of beauties.
We enjoyed the one night we spent in this campground, but it isn't much of a wilderness experience. It's much more like camping in a city park, streetlights and all. Still, it's very close to the old bath houses that make this National Park interesting. I recommend a visit if you're in the area.
