We love going to Thomson Causeway. It was a wonderful surprise, and greatly appreciated, when we found water at all the sites!! Thank you thank you.

This Corps of Engineers campground never disappoints! We've visited every year for 6 years. Roomy, concrete sites with plenty of shade in the PMAN loop right on the Mississippi River. Beautiful sunsets. At this particular visit, some severe weather was moving through and the Thomson Fire Department rolled through the entire campground warning everyone. That was very much appreciated. Make your reservation now - you won't regret it!

Water at every site is a great upgrade. Great campground, love that we can ride bikes “uptown”, yet seems we’re remote.

I understand the water is still higher than before but the grass on the sights 114 and 118 is so tall. It hides the rocks of the shore, makes the sight much smaller (almost tight) and breeds flies and mosquitos. We were constantly spraying the air and ourselves with bug spray and still came home with 20-30 bites each. Was terrible. We all agreed that the tall grass didn't help. It blocks the views when sitting watching the sunset. We stayed at 114 a few weeks ago and thought the same and last week stayed in 118. Both need the tall grasses cut back. We camped here in 2020 & 2021 and loved it. Last year we couldn't due to some family health problems, so I was so looking forward to coming back in 2023. Booked 3 trips. We are currently here on trip 3 but I'm not sure it's my favorite anymore. Sorry, but it is so well maintained except for the river edge. REALLY needs some care on river edge. I wish the water was lower to use the little sand beach, but that's probably out of your control so that I can overlook. Thank you

Excellent campground. Great view of the Mississippi. Clean, well kept, with courteous staff. Lots of things to see and do in the area. Don't miss tour of lock and dam 13. Also nearby Fulton has windmill and other attractions. Across the river at Clinton are many more things to see and do. It was a great trip with the grandkids.
