Late Fall, Winter, and Spring
Summer and Early Fall
Guided tours in May through October are offered as staffing, weather, high temperatures, and group size permit. Please ask or read postings at the front visitor center information desk to learn about tours, special events, or guest speakers featured on the day of your visit.
Tours Inside the Great House
No tours enter the Great House due to safety and resource protection concerns. There are bats, insects, birds, and other animals who make the Great House their home or hotel. Most of these residents, or their droppings, are unhealthy for humans to meet. The wear and tear on the Great House from tours would also do permanent damage, vandalism aside. And, as discovered after a 1974 earthquake, there isn't much holding the Great House together so it is best we leave it be.
Fees and Reservations
Entrance to Casa Grande Ruins National Monument is free. Unless you are bringing a group of 15 people or more, or if you need special accommodations, there is no need to make a reservation in advance. Special tours such as backcountry archeology walks are sometimes offered in the spring. Please contact the park in advance as these programs fill quickly and will require reservations.
