We always enjoy camping here. The campsites are excellent with electric and water. The scenery is amazing! We enjoy watching the sunrise and sunset from the shelter along the Mississippi River. We love the River section for camping -perfect for watching the river traffic! The campground is clean and quiet even when full of campers. If you enjoy hiking or cycling this campground is adjacent to the Great River Road Trail. Highly recommend camping at the Thompson Causeway it's an excellent campground with a friendly informative staff.

Lower bathhouse had many snakes under and around it. Was very hot today in bathhouse fan not keeping air moving. At top bathhouse the outlets did not work. Overall we love going to Thompson for camping.
Thank you

Beautiful view of the widest pool in the Upper Mississippi River. 3 miles wide, the barge channel is 2.5 miles out from shore. This makes for a quiet day as boat traffic cannot be heard. Fishing is good right off the shore. A ramp is available for launching boats, canoes, and kayaks. The Great River Bike Trail runs along the edge of the park, offering a 6-mile ride to Lock and Dam 13 or a 12-mile ride to Savanna, IL. Try to catch a barge running through the lock, a fascinating example of engineering.

A very nice park. It was great to have 50A and water at our site. Some sites are too close but overall very nice. Very quiet for our stay.
