Nice sites...awkward access. There are two sections of this facility: East and West. You are directed to check in at the West unit for both sections. The check-in booth at the West unit has a narrow access lane (notice the scars on the eves!) After checking in you are directed on a small road (Prairie Du Chien) to the East unit. We would like to see the need to pull into the West unit eliminated. The road into the East unit is hilly and curvy, make sure you have good brakes! The sites are nicely done with adequate room. The East Section was clean and in good repair. We stayed here to visit the Herbert Hoover Presidential Library and Iowa City.
