Your grandparents backyard
Stayed here for one night. My family enjoyed walking on the bridge over the Cheboygan River. This campground has boat access to the Cheboygan river and access to what I am told is 40+ miles of biking trails. There are small apple trees around the campground and it is all well kept. This campground has a homey feel and will remind you of your grandparents backyard.
Downside, you have your grandpa nagging you.
