Permits are not generally required for camping in Iowa's state parks, but you will need to pay fees and make reservations for campsites. To reserve a campsite, you can use the Iowa State Parks reservation system. Fees vary depending on the type of campsite and amenities provided, such as electricity and water hookups. Some campgrounds operate on a first-come, first-served basis, so it's a good idea to arrive early during peak camping season. You can explore various camping options in Iowa, including forest, river, and fishing camping, on Hipcamp. Be sure to follow the rules and regulations of the specific park or campground you choose to camp in.
