We came to visit the trolls in Clinton and ended up enjoying the river and bicycle trail! This is a great campground, clean restrooms, level sites and beautiful Mississippi sunsets.

Very clean, well maintained campground. Beautiful scenery with the Mississippi River especially sunsets. Most sites are completely flat and are on concrete pads.

We stayed at campsite 74 and had a nice partial view of the river. It was a short walk to watch the beautiful sunset on one of the benches. Very quiet place to relax for the weekend. We also enjoyed walking the recreation area. Will definitely return next season for a longer stay.

This is always a great place to camp. It’s nice having water and electric. The Mississippi river is always cool camping next to it. A lot of awesome wildlife. Easy access and spacious sites. Will camp here again.

I was happy with the cost of the sites. I thought it was reasonably priced. I would suggest planting grass on places where there is dirt/mud on each campsite.

2nd time visiting and still like it! We stayed at site 65 right on the river and enjoyed the view and birding. Very quiet!
