Things To Know Before You Come

Exploration of new things and new places may require new skills. We want you, your family, and even your pet, to have a very safe and enjoyable visit at Casa Grande Ruins.

Please remember that the park is located in the Sonoran Desert. In the summer that means very hot and dry conditions. Even in the 'cooler' seasons we run very warm!

If you have discovered you forgot an essential- a hat, sunscreen, lip balm, etc- do check in the park bookstore for such things on sale. An ounce of prevention is truly worth a pound of cure, especially as regards sunburn or the potential for skin cancer. Plan ahead!
