Clean bathrooms, easy access to bike trails, friendly staff, large concrete sites so no leveling involved. 2 loops were right by very swampy ,green, stinky stagnet water.

I love the full hook-up concrete pads. The campground and the bath houses were clean. We had great view of the river. The bugs are the only negative.

The area has lots to offer families and retirees. Great bike trail extends North and South right from the campground. Bike or drive to Lock and Dam #13 very close, Fulton IL Heritage Canyon, deImmigrant authentic Dutch windmill that grinds and sells flour along with very interesting Cultural Center with a fantastic collection of built to scale model windmills.
Drive to Clinton IA lumber mill museum for lots of local history and interactive things for children indoors, Four Thomas Dambo trolls are located in Clinton. Good food at Tin Roof on Rt 84 and specialty coffees at The Pour on 84 next door. Steam Anchor Cafe in Fulton also has coffee and deli style food. Dusty's in Thomson good food and great pizza. Clinton offers all of the fast food stops along with pub style and fine dining, movie theater.
The campground has access to Mississippi River for kayaks, canoes and fishing boats, or fish from the shore. Views of the river are spectacular with breathtaking sunsets. Indian mounds within the park date back to 100 BC. Pleasant walking along the river in the park. This campground is clean and everything is well maintained.

The sites were basic electric and water with a dump station outside the park. Pit toilets in the loops and a couple of bathhouses spaced well apart. The mosquitoes were active so be prepared. Nice place to stay for a short time especially if you’re visiting Clinton IA to see the Dambo trolls
