We had a great experience at Thompson Causeway! Campsites are clean, well kept and easily maneuverable. The staff is super friendly and helpful. The showers in Potter’s North were the push button kind and super hot with great water pressure. We love that the bike trails to Fulton and Savanna are easily accessible from the campground. We will definitely return.

Rained most of the time....we came home a day early. Can't get any tv reception ! I would suggest you get wifi up there. With so many trees. Charge for it if people want it. I would def pay extra. This trip to Thomson wasn't our best but we'll be back.

As expected the shambles came in a bit. With the rain, we decided to visit the Sawmill and find one of the Clinton trolls.

Frequent storms were the only negative. This caused soggy grounds & flooding. Nice sites. Great scenery, bird watching & General views of Mississippi River.

Clean and tidy as campsites go. Ranger assisted with a downed tree limb in my campsite after the storm. No damage to my equipment. I’d go back.

Lovely site looking over smaller marshy area. Quiet and shady, nice breeze so minimal bugs. Lots of birds to watch and even a deer that comes out every evening on the other side of the water. I extended my stay for the full 14 days it was so peaceful here. 💖
