Clean bathrooms and roadway. Was not able to stay last year, but the cleanliness and interactions with the Ranger staff was a great improvement. Have always loved this campground and will continue to stay

I have been camping at Thomson Causeway for over 15 years and I have to say I enjoyed every visit ! My wife and I enjoy bike riding, cooking out doors and just relaxing and enjoy the views. The Army core of Engineers of been up grading little by little each year and have done an Excellent job to raise the standards for all parks to strive for ! They have a great staff of volunteer's and the people are very welcoming and helpful ! I'm looking forward to are next visit !!

We had a great time. The fact that the weather was perfect did not hurt. ;-) We really enjoyed watching the wildlife and riding the Great River Bicycle Trail. One concern is that the site picture online was different than reality. The "no concrete" site had recently been upgraded with a concrete pad. For most, this would be a happy surprise. For us, it meant putting up our changing tent was challenging (we travel with a very small trailer in which we cannot stand up). Also, depending on which site you choose, the closest may be only pit toilets.

What an absolutely beautiful campground! We had such an amazing view of the river. The sites were level, and nicely arranged. We look forward to visiting again!

Beautiful views. Could use another shower house - only put toilets were within a reasonable walking distance from our camp sight.

very nice campground, Good power, reasonable bugs, good wildlife, clean restrooms and civilization resources just across the bridge over th e river! It can feel a little crowded if not reserved early and smartly

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
