This is a beautiful campground. The good comments from other campers are mostly true. Friendly staff. Scenic location. Well maintained.
There are 2 downsides that KOA can not correct. That "sewage" smell is not sewage. It is the smell of decaying plant matter. That old bog black mud smell. It can be strong along the shore.
Then there are the bugs. The ones we experienced that covered up everything one day are apparently seasonal. Pesky but a fogger will disperse them, so come prepared.
We enjoyed our stay. Set your expectations, and you will too.
