One of our favorite campgrounds. Very clean and spacious sites. We were on site 3 which is very long and is concrete. Plenty of walking trails near by.

The site was excellent, we experienced many different types of wildlife, including sandhill cranes, a pair of mated eagles. Our sunsets and the clouds we experience were amazing. The core of engineers really knows how to pick great Campsites.
