Everything about Thomson Causeway is great. The marshes and shoreline are fantastic and sunsets across the river are always spectacular. You can find everything from sand prairie to riparian forest within a few miles of the campground on the Great River Trail which is the main reason I camp there. The campsites are flat, level and well maintained and the restroom-shower buildings are clean and have plenty of hot water. I'm just happy we are back to being able to do same-day arrivals without reservations so I can again enjoy one-night stays at Thomson Causeway when riding the trail.

Bring lots of mosquito spray. Plan for the "old" check in system as this park hasn't caught up with the, much handier and newer check in at your sight system. Staff is not particularly cordial or helpful.

We come to Thompson Causeway several times a year. Never stayed in the River Loop. We got a good site looking out at the Mississippi River. Liked the spot.

Definitely needs more parking in the camping areas. The sites are a bit close to each other. And could be longer. Again i had to park my vehicle a half mile away and walk to my site.

Nice place, enjoyed the wild life, turtles , deer, crawfish, birds. The mayflies were bad the 1st few days but then they were gone. Bath house was clean and the showers hot.
