Summer daytime temperatures frequently exceed 100 degrees F. Winter temperatures range from the 60's to the 80's F. Spring and fall are warm and dry, with highs in the 80's and 90's F. During summer months, be prepared for hot temperatures. Protective clothing, hats, sunscreen and personal water containers are highly recommended.

Casa Grande Ruins National Monument

Construction began in 1932 to create the current adobe visitor center. Funding was provided for only half of the open square building, final completion was delayed until 1956. Exhibits, restrooms, bookstore, and orientation movie are available in the current building. All park visitors enter the historic area by passing through the visitor center and paying their entrance fee.


Welcome to Casa Grande Ruins National Monument.
This one square mile park was set aside in 1892 to preserve what remained of an ancient Sonoran Desert people's community and irrigation system. You can learn more about the park history in the History & Culture section.

Special Events

Check out our Calendar page for special happenings and events going on in the park. There is generally more happening in the cooler fall and winter compared to the nice hot summer months. Past events include a Speakers Series, Arts Festival, Archeology Month Hand On Events, Demonstrations by Native American Artists and Craftsmen, Junior Ranger Day, Fee Free Days, and so much more.


Well behaved pets under physical control (usually a leash 6 foot long or less) are welcome. Please don't let your beloved companion stay in a vehicle where it can get very hot very quickly. You may NOT leave your vehicle running to provide air conditioning so bring your buddy with you. Don't forget to bring your equipment for cleaning up after your pet, too.

Fun for Families

Well behaved children can find some excellent adventures using the park Junior Ranger book and speaking with park volunteers. Scout groups who call and plan in advance may visit to earn patches, badges, knots, and many other awards. Look at the For Kids section for activities to do before your visit as well.
