Passes

Because Effigy Mounds National Monument does not collect an entrance fee, it cannot sell or issue interagency National Parks and Federal Recreational Lands Passes. Passes can be obtained through the mail or at participating recreation sites that charge a fee. Always call ahead to ensure the recreation site is able to issue the pass you are seeking.
