Casa Grande Ruins National Monument is Fee Free
Casa Grande Ruins National Monument no longer charges a fee to enter the monument. The annual and senior passes are no longer available for purchase, however we are still able to issue the free passes.
Casa Grande Ruins Picnic Area is closed through April 30, 2024
Casa Grande Ruins picnic area is closed March 28 - April 30, 2024, due to the density of an invasive and noxious weed called Stinknet, which can cause skin rashes and serious breathing problems. The park is working to open it back up as soon as possible.
