  • Visitor Center Rennovations

    Park is having major heating/cooling system work done. The Visitor Center is closed (we don't know how long-mid July?) but restrooms, movie auditorium, historic ruins area, and picnic area remain open (no fees or pass sales during rennovation)


This page is a work-in-progress just as the studies and listings of animals at Casa Grande Ruins National Monument continues as a work-in-progress.


Some of our park visitors have discovered that the desert can be a great birding hotspot. We have been lucky in having talented photographers forward pictures they have taken at Casa Grande Ruins so that we can share them with you. You may see these wonderful gifts on the birding page. If you have visited the park and have pictures to share, please let us know. You are always welcome to use the 'contact us' link on each page.


Of course there are mammals within the park boundaries as well. The most abundant, and quite the crowd pleaser for most of the year, is the round tail ground squirrel.
