We've always had a great time at Thomson. There is a lot to do and the sites are clean and spacious. During the week it is quiet. We avoid the weekends. Bike trails are convenient, and there are plenty of things to do in the area or you can just sit and watch life go by.

This is our favorite place to camp and relax. The sunsets are breathtaking, love camping right along the Missippi, and the camp ground is very well kept. The people running it are friendly and approachable and always willing to help.

As always, this is a very relaxing campground.. Nice level sites, electric only. for adults there’s kayaking or riding the trail outside the park north or south, and fishing. Some hiking nearby (small trail in park, usually very buggy). As two mature adults, we love staying here for the relaxation.

Beautiful campground all around. Our site area was our entire group, right off the river. Peaceful, spacious, and overall a fantastic experience. Bathrooms were clean for shower and public use. Will definitely be going back annually with family group from here on out.
