This was our first visit to this beautiful campground. We had site 87 in the River Birch campground loop. The view and space were all I had hoped for and more! We took time to ride through all 4 campground loops and the day use area. The south Potter loop looked a little too wooded for our preference but there were a LOT of nice sites in all the loops. There were five shared water spigots in the River Birch loop, two of them actually on the outside of the loop, across the road from campsites. These two were useful for anyone entering the loop to fill their tank. It would have been nice to have a small dump site for "turd toters" at the shower house nearest this loop like the one in the north Potter loop. Having a local site would save towing waste all the way to the main dump station which is "outside" the campground areas. Each loop had a a playground area, as did the day use area. Each playground had different equipment.

We had another great time at Thomson Causeway. The weather was good and the bugs weren't too bad. A bike ride to Fulton is a nice thing to do if you are willing to ride 18 miles or so. It is on a bike path for the most part so you don't have to deal with traffic, although the pavement gets a little rough in stretches. The worst thing about our time there was the showerhead in the shower stall I used. The water came out with very high pressure so it felt like you were getting sand blasted. It hurt if you stayed in one spot too long. Not so good for rinsing off your face.

We loved the camping spot right on the water. The facilities were clean and even though it was HOT, the breeze off the water made it tolerable. Gorgeous sunset. Hope to go back!

We enjoy the great scenery, large campsites and good access to the river. It does seem to be a very buggy location though. Difficult to sit outdoors for very long and not be tormented by gnats and flies.

We were only there for 2 nights but would have enjoyed the view of the river and sunsets for much longer. The 50 amp connection was stable & uninterrupted, which was great because we needed both AC units as the temps were in the 90s.
We also liked the way the sites are layed out with a decent amount of space. And the shade of the mature trees made sitting outside on the concrete patio enjoyable.
We brought water onboard, but we noticed several hydrants that we could have used for fresh water. Finally, the dump station on the way out could facilitate at least 3 rigs at the same time.
The only minor inconvenience was that we were unable to check in on the phone, as the phone in the ranger booth at the entrance was not working.
