Very nice COE campground. Location is nice, not much locally - but Clinton IA is 9 mi away.
Campsites are level, and easy back-ins.

Great place on the river -- saw 5 tows go through the #14 lock which is close to camp -- clean place with low water pressure in the showers but the water was the right temp. -- I/we will be going back -- Voulonteers are the best!!

Nice campground. Quiet. Much wildlife in stream off of the Mississippi River to view. Campfire could have been a little farther from trailer but ample wood available from camp host and easy to purchase. Would return

This is a very nice campground. Mayflies were prolific but that’s to be expected by the river. Families with kids showed up on Thursday with their bikes and the parents hadn’t trained their kids to respect other people’s campsites. I’d say that was the only drawback to the experience.

Nice facilities, easy access to drinking water, and the campsite was literally on the bank of the Mississippi. The pit toilet was the right distance away (not too far away, but not too close either) and the modern restroom/showers were a short walk up the hill and clear the whole weekend.
Overall it was a nice experience, the campground is RV oriented, but we used a camp without issue. There is easy access to the bike trails in the area.

Rained a lot. We had puddles on our lot and on the road in front of our site. Was fun watching the kids ride their bikes through the water. Nearby attraction is the Dutch Windmill at Fulton ,IL. Bear's Drive Inn at Thomson messed up our food order twice.
