Let’s start with the pros. Nice grounds. Great park and jump pillow for the kids. Well stocked store. We stay at KOAs all over the country and this one is middle of the road. No one spoke to us during our entire stay (could be considered a pro or con). The reason for only 3 stars is the proximity to the busy road and train tracks. You can hear traffic and trains all day and night. Some of the spots could be difficult to navigate with a bigger rig as well. About 30 minutes to St. Louis Arch. 5 minutes to six flags.
