The 344 acre Preparation Canyon State Park is a remote and lovely area still relatively untouched by humans. The park is located in Iowa's unique Loess Hills and is surrounded by dramatic ridges on the north, south and west. The Loess Hills, made of yellow loess soil overlying older debris left from the last ice age, are characterised by cliffs cut by rivers and streams, steep ridges, and gentle slopes. It provides a beautiful backdrop for hikers and family picnics. Picnic tables, a shelter and non-modern toilets are provided. In order to help protect the canyon's natural seclusion and the remaining evidence of its dramatic past, camping is restricted to hike-in camping only at the designated sites. Preparation Canyon State Park lies at the very north end of Loess Hills Pioneer State Forest, now under development.
