What Guests Are Saying
Thomson Causeway is praised for its beautiful riverside camping, clean facilities, and friendly staff, making it a favorite among visitors. Campers appreciate the spacious concrete pads, proximity to nature, and stunning sunsets over the Mississippi River. While some concerns were raised about noise from barking dogs and a less-than-friendly host, the overall experience is highly positive, with many planning to return.

Our first time at Thomson Causeway. We spent the last week of the ‘24 season in site 114. Stunning location. Very pleasantly surprised to fine water at each site. Most sites were well spaced. Paved roads with level concrete pads. Restroom's were clean and supplied. Close proximity(~20 min) to Clinton IA for whatever you need. Verizon coverage was sufficient. We’ll be back!!

All the campsites are nice but, it would be helpful to have some sites that don't require a reservation.
