If you've camped at a KOA before, then you know what you're getting here. Easy on, easy off I-75. It's close to the interstate, but the noise was never intrusive. Mostly because of the stiff wind blowing out of the North. 

  The sites are tight, particularly the inside pull throughs. The back in sites are more spacious, though that's relative. Site 7 is a very spacious back in site. 1-6 are by Trails End Road, but it isn't really that busy or noisy. I would get a back in site, especially if you can get away with 30 Amp service. 16-20F  are back in sites with 50 Amp. There are some deluxe pull throughs with patio & grill on site. There are some extra long pull through sites.

   There are the usual KOA amenities like a heated pool, playground, a game area & bike rental. There's a nice hiking trail in the back. It takes you to the bike trail, so back track back to the campground unless you want to walk on the bike trail/road. 

 What makes KOAs & this KOA special are the clean bathrooms & showers. It's always a pleasure to know that a shower will be KOA clean!

 Staff was courteous & efficient. They delivered ice & wood to your site. 

This is a good base camp for the area. I would stay again if in Mackinaw City!
