This rating is for the Cottonwood section of Foss State Park. It was a very disappointing stay. We stayed in the full hookup section of this area. You can literally touch the camper next to you due to the cramped sites. The neighbors sewer hookup ran under our awning. The grass is almost knee high all around here even at the site. This section is not maintained at all. Lots of people partying late nearby as well. The tent camp section was bad as well. Grass so high it was almost 18 inches tall. This section is nowhere near the lake. I hope the other sections of the campground are better. AT&T cell service was unusable due to weak signal. Verizon was good.
