Kern Valley State Prison is located in Delano, a culturally diverse community that celebrates their culture and heritage with festivals throughout the year. There’s the Cinco de Mayo celebration in early May, put on by the Cinco de Mayo Fiestas Incorporated, and a few months later, the Filipino culture is celebrated with the Philippine Weekend, 30 years old and still going strong. In the fall, there’s the Harvest Holidays, a four-day festival of fun. Agriculture is the heart and soul of the community. There are 260,000 acres of citrus groves in California; 70% of those are in the Central Valley and 121,000 acres of table grapes grown in the counties of Fresno, Kern and Tulare. The Delano Breezeway Murals are a must see and a way to showcase the culture, agriculture and the people who shaped a way of life in this Central Valley community.

Local Inmate Family Councils (IFC’s) are a gathering of family and friends of the incarcerated who meet regularly with Wardens to support visiting since keeping strong family connections with loved ones is a powerful rehabilitative tool. These IFC’s promote visiting by clarifying rules and regulations as well as discussing health, education, vocational training, packages, books, and related issues.
