Very level site!. We got to see a beautiful sunset, despite all the flies and mosquitoes! At this point, the Mississippi is at it's widest, 3 1/2 mi wide. We got to picnic on the water! Lots of critters in this eco-system. Turtles, beaver, bullfrogs, herons, dragonflies, deer and a red-headed woodpecker!! Potters South had a lot of empty sites because they had a lot of new sites poured! There was a dump station at the beginning of the campground, but it also featured a gray station dumpsite for those portable gray tanks that we all use. There is a boat ramp

This was our first time camping at Thompson. It was amazing. We thoroughly enjoyed the wildlife, water views and wonderful area to hike. We we defiantly be back. Hopefully yet this year.
Thank you for a wonderful time.

Our loop had problems with power. (Site 60) There were multiple power surges almost every day. We have a good surge protector which shut off our rv power to protect it from damage. Our neighbors had the same problems. We left a day early as it was hot and we were tired of the power going out. We loved the campground otherwise.

Love the views. Met a former co worker for the week. Usually yearly, last year flooded out. Love the improvement of pads and new pedestals in South, and more water hydrants in Potters.

I incorrectly picked out my site on the map and when I arrived there was disappointed. The recreation booth opened at 4pm so I drove around with the campsite map open on my phone looking to see if another spot was available. There were a couple great spots right on the river. When 4pm came I stopped by park booth when a very helpful and friendly staff member changed my reservation in seconds to the new spot I wanted. Very nice experience and will keep this tip in mind on future trips if needed. Thanks, Bob

Thomson Causeway is our favorite campground! Large sites, clean bathrooms and so peaceful and quiet. We love to ride our bikes and kayak on the river. I wish we could go more often.
