Very nice campground. The sites are level concrete with newer electrical hookups. Each site is angled nicely so you’re not looking directly at your neighbors site. Easy access to the Great River Trail. We will definitely be back.

Always enjoy our visit to Thomson, Illinois. Just love the setting--along the beautiful Mississippi River.
So much to do in the area. We like to go into Clinton, Iowa which is just across the bridge into Iowa. Plenty of good places to eat within a 15 mi radius of Thomson. Depending on what quisine appeals to you.
Nice biking trails from Thomson to either Savannah, Illinois or to Fulton, Illinois.
We personally try to make it to Thomson Causeway 2 times per camping season---a week at a time.

Our favorite spot. Mayflies were out in force but they didn’t scare us away.

I have camped at Thomson Causeway many times. Each and every time I find something new and amazing. The wildlife is everywhere! The sites are level with electric and water hook ups. Just a great, relaxing time.

This was my second camping experience on the Mississippi River trail and it was even better than my first one at Fisherman’s Corner. The views and overall scenery were serene and beautiful.
Facilities were great again as usual.
