GuideThe location to St. Louis is great, and the utility hookups for RV were convenient, but there was ZERO privacy at the sites and hiking trail were extremely limited. Great coverage for Verizon and Starlink.
TravelerThis place was amazing other than the humidity (mid july). Showed up and the hosts were super nice and helped me to my spot. They have lots of camper spots, most seemed like long term campers. I used a tent and had a great spot near the lake. No other tent campers around. They have a good open spot for tents that you just find a spot and set up. Campers seemed nice and we re quiet.
GuideGreat views. Lots of water view sites. Just not a lot to do in the area. Hosts are very kind
GuideBeautiful grounds. Paved level sites. Great path around the lake. Wish there were trees
GuideThe grounds are so well maintained. The spaces are level and paved. The path around the lake is awesome. A lot of activities in one location. My only issue is no shade. It’s a newer facility so the trees are not mature.
GuideNice campground with full hookups. Only one row has shade since the campground is so new. Shower house is good. My only negative is the wifi was weak in the two spots I stayed in.
ScoutThis is close to the Arch but not well maintained and security is lacking, No staff onsite and the gate is broken. we heard gunshots at 2 AM and left early the next day.
ScoutWe camped here for 5 nights. It is so clean and well maintained. It’s quietly tucked in along the Mississippi River (except for a train that runs nearby). Nice level concrete pads with electric hookup! Water (not potable) and dump available. It’s close proximity to everything in the St. Louis area can’t be beat!
GuidePulled in after the office had closed. They knew we would show up late. Around 1930. Still light outside. Opened the after hours check in and there was nothing for us. Or a map. Luckily there was a number to call. We called. Lady said she was on break and would call us back. Never did. After digging through emails, we finally found what site they had assigned to us. Very small print. Due to this app we were able to use the map posted. However there was no p10 site. Just up to p09. Called the lady back. Said there’s a p10 but that she would move us to p9 in the system. Just decide to stay because we’ve been driving all day. Beautiful grounds/location. Enjoyed a nice sunset. It’s sad it’s “kept up” by these people who can’t help someone because they are on break. Appears a lot of the campers live here. Which to me doesn’t matter. But it does when you can’t help someone for 5 min. Campers are nice. Bath house is a bit dirty. But usable. Skipping a shower tonight but the toilets and sink work.
