DirectionsOfficial site
Yuma Territorial Prison State Historic Park

Surviving cells, the guard tower and museum interpretation introduce the lives of the people confined here and the harsh environment around them.

Explore the site as a historic prison rather than a working correctional facility. Outdoor areas can become hot, so plan for sun exposure and check the operator’s current visiting arrangements. The park is close to downtown Yuma and other Colorado River heritage sites, making it useful as part of a broader local-history itinerary.
