About
Overview
Thomson Causeway provides the unique experience of island camping on the great Mississippi River and it's well worth a try!
The western edge of the recreation area offers visitors an unobstructed view of the widest spot on the Upper Mississippi River Basin, 3.5 miles from shore-to-shore. Here, campers can enjoy memorable views of the river and the valley, and partake in plenty of great water activities.
Recreation
Popular activities include fishing, hiking, hunting, biking and boating. Common fish species include the channel catfish, bluegill, walleye, large mouth bass, and northern pike. The Central Trail section of the famous Mississippi River Trail passes beside the campground, offering visitors miles of walking and biking trails along the river bank.
Facilities
Of the 125 reservable campsites, 120 have electric hookups and 5 campsites do not have electric hookups and are for tents only. Campsites in the Hickory, Potters South, and Potters North camping loops have water available at each individual campsite. Thomson Causeway provides the comforts of modern camping, including drinking water, an accessible flush toilet, electrical hookups, shower house and boat ramp, while still providing visitors with an authentic outdoor experience. This park also offers 2 reservable picnic shelters for day use.
Natural Features
The campground is built mainly on an island in the backwaters of the Mississippi River. Slow moving water on the eastern edge of the main recreation area creates a rich environment in which wildlife and fish abound.

Is THOMSON CAUSEWAY fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
