Casa Grande Ruins National Monument is a unique structure built by the Hohokam Indians in the 14th century. The Big House stands an impressive four story building. The ruin is 40 feet by 60 feet at the base and some of the walls are more than 3-feet thick.

Explore the mystery and complexity of an extended network of communities that rivals today's cities. An Ancient Sonoran Desert People's farming community and "Great House" are preserved at Casa Grande Ruins. Whether the Casa Grande was a gathering place for the Desert People or simply a waypoint marker in an extensive system of canals and trading partners is but part of the mystique of the Ruins.

Guided tours are offered nearly hourly from late November to mid-April. Tours meet in the shaded Interpretive Ramada located immediately outside of the visitor center's rear doors. While you are seated for the introduction the guide will explain the history of the ruins, the archeology, and the Hohokam Culture. Your guide, either ranger or trained volunteer, will then lead the tour into Compound A and point out interesting features. You may enter or leave the tour at any point, or you may chose to visit the park on a self-guided tour. There are signs and exhibits to enhance your visit with volunteers and staff eager to hear your stories and discuss your questions. Tours are wheelchair friendly.

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.

No tours enter the Great House due to safety and resource protection concerns.

There are no additional fees for guided tours. Special tours such as backcountry archeology walks are offered in the spring. Please contact the park in advance as these programs fill quickly.
