Swan, Iowa
We stayed here 10/2 and 10/3/20. One of the best boondocking sites we have been to. There are ten designated sites here and you must register at the kiosk at the entrance of the campground (this is towards the end of the road, you will go past a pavilion and up a hill before you reach the campground). The sites have picnic tables and fire pits that are inlaid in a cement patio. There are bathrooms at the entrance to the campground. And, the kiosk at the entrance has a map of the park which shows some hiking trails that can be accessed from the campground.
