Booked on-line, check-in was seamless.
I love having water at each site! Great improvement.
Shower house and campground was very clean.
I camp here 4~6 times a year to ride the Northern half of the Great River Trail.
Dusty's is a great place to eat, and there is a bar across the street. Also, on the same block is Arnold's Bike Shop.

1st time staying here. Reservations were very easy to make. Met friends with their 34' 5th wheel on site 68. Ours is a 32' 5th wheel and we were on site 70. Plenty of space for RV and tow vehicle on very good concrete slabs. Visited near-by Lock & Dam, Fulton (groceries), and Savanna (pizza restaurant). Been to Poopy's restaurant in Savanna in the past - highly recommended though we didn't go there on this trip. Campground very quiet and relaxing except that the mowing crew started at 7:30 AM. Very nice dump stations - easy in and out. Great stay - highly recommend. Will stay here again.

One of my favorite camping parks in the upper Midwest! Large sites, most now have water connections! Clean showers and bathrooms. Great place to ride bikes and view the Mississippi river.
