Campground at Chain O Lakes State Park is a moderately wooded campground with standard sites. Some camping sites are more private than others and caters to RVs since many of sites are not level. They have a primitive loop with flat sites which makes for great tent camping. The beach is a fun activity for the kids and there are several lakes linked together via narrow creeks which can used by canoes and kayaks.
There are three campgrounds on South Manitou Island. I have stayed at the Weather Station Campground. The sites are back country camping with little to no amenities. A few sites are secluded while others are close together. A few sites offer amazing views of Lake Michigan atop some small bluffs which make this campground amazing. The area has a pit toilet or you can use nature and bury your waste (follow LNT principles!). The solar driven well is no longer operating so grab your water from Lake Michigan and treat it accordingly. This is a fun back country campground.
This is your typical KOA campground. Sites are close together with not a lot of trees. Activities for the kids are numerous and they really enjoyed the large jumping pillow. Cable hooked into the RV didn't work. Park is named Traverse City KOA but it is actually a half hour south the Traverse City so I would choose a different campground if you plan regular activities in Traverse City.
Awesome rustic campground in Leelanau State Park. Sites are very private and well situated. You can hear the waves crashing onto shore and the light house offers tours which was a fun experience. Cons to the campground are the views of the water, there are lot of undergrowth vegetative bushes which steal the view and the mosquitos were high in numbers in the spring time. There is no beach near the campground so no swimming.
Lower Falls campground at Tahquamenon Falls State Park is a great stay while visiting and recreating at the falls. Sites are evenly spaced in a fairly wooded area. Some sites are close enough to the river to hear the rush of water (even though you can't see it from most sites). The trails near the falls are a lot of fun to hike. Fishing from shore on the river below the lower falls didn't produce much (a full small trout). Overall this is a beautiful campground and state park.
Cedars campground at Ludington State Park is nice campground with an amazing beach and river area. The sites are well spaced but the campground overall is not well wooded, especially the sites in the middle of the loop. Trails are great for walking/bike riding and the beach makes this campground worth it. Campfire rings are very well made which is a plus.
Bay Furnace Campground in the Hiawatha National Forest is what you expect from a NF campground. Sites are very secluded in a well wooded area with a few sites right on the Lake Superior shore with a view of Grand Island. Most sites are very level and good for tent camping. Non-electric sites gives the campground a rustic feel. The shoreline is excellent for walking the beach and looking at the beautiful washed stones, but there are no sanding areas to swim (if you could even brave the cold water).
Covert Park is an above average municipal park with two small loops. The short walk to the beautiful beach makes this campground worth it. Bathrooms and showers were well maintained. Cons are the sites are extremely close to each other separated by heavy rope attached to posts.
Platte River Campground on the southern end of SBDNL is an awesome campground. Sites are well spaced in a wooded area with paved parking at each site. Most sites have tent pads which have been specifically leveled. Bathrooms were well maintained. This campground was well thought out ahead of time and is a great place to stay while visiting SBDNL.
Pokagon State Park has an excellent state park campground. Sites are in a well wooded area situated on 5 different loops (1 non-electric, 4 electric). Many sites are flat (good for tent camping) while others are slightly rolling hills (helps breakup the sites a bit). There is a lot to do in the park including many trails, horse riding (horse stable on site), and lake swimming on a nicely improved beach. Only cons are no full hook up and the fire rings/grills could be improved.
