I grew up in the area and we like full hook up sites. When we go back a couple of times a year we stay at the Lena KOA, about 25 minutes east of Galena. It is a nice scenic drive to Galena taking either US 20 or the back way on Stagecoach trail. Take time to go to Chestnut Mountain, there is a great Alpine Slide there and the view of the Mississippi river valley is fabulous. Cave of the Mounds is kinda cool too, it is close by. Have fun!
