Electric went out 1 day and water the next. Both were taken care of right away. We were notified about electric but not the water but we managed

Bathrooms were clean, volunteers rode around checking sites. We don’t have one bad thing to say about Thomson-it was a great stay!

The camp site (068) was clean, good shade, friendly neighbors. Easy check in and out. The only bad part was the bathroom air freshener some kind of ventilation system very much needed but otherwise had a great time.

The addition of water pumps at each site is enormous - great benefit to lovers of Thomson.
The campground is kept VERY clean and in that sense VERY enjoyable.

Our campsite, #67, was great, the view of the Mississippi River was excellent, especially the sunsets. The biting flies were bad but expected. A wind storm coming across the river was scary, but not the fault of the campground of course. The upgrade to the campsite with a water hookup was very nice and we liked the concrete pad even around the fire ring!

We were in the loop that was on the lily pad marsh (site 18). It had rained...other sites had flooded, roads and site pads stayed wet and muddy all weekend. The other two loops were beautiful 😍 and on the river. One note...many areas of mud caused by trucks not having enough room to back rigs in, and driving over the grassy area. Even if site accommodates your rig, the street is narrow. There is a hiking trail, but due to weather, we did not use. We will return, to one of the other loops.

Beautiful location with picturesque sunset views. Bugs were bit intense during the evening due to annual swarms at that time, but well worth it for the quiet & time with nature. My family will definitely return in the future.

When we got there at check in time we went to our site and some other people were in it. We were confused so we went to the front gate to talk to the attendant and told her. We said we would take another site nearby so we did. After setting up our site for almost an hour the people who were on our original site left. We had already set up so we stayed at the 2nd site. We were upset because we had booked that original site months ago. Other than that and the shadflies coming out of the river, it was nice.
