Mule Creek State Prison

Sponsored Links

Mule Creek State Prison is state prison for male inmates that is located in Lone, California. It was designed to hold a maximum of 3,284 inmates, but it currently houses over 4,000. MCSP houses long-term offenders, and it has a re-entry program to help inmates who have been incarcerated for a long period of time learn how to successfully reintegrate into society.

MCSP is the only California state prison that is exclusively for Sensitive Needs Yards inmates. These are inmates who are segregated from the general prison population for their own safety because they are gang dropouts, informants, sex offenders, and former law enforcement officers.

Notable current and former inmates include:

  • Robert John Bardo, who is serving a life sentence without the possibility of parole for the murder of actress Rebecca Schaeffer
  • Roger Kibbe, also known as the I-5 Strangler
  • Lyle Mendedez, serving a life sentence for killing his parents

Mule Creek State Prison has an 800 Visitors’ Information number (800-374-8474) that you can call for up-to-date information on lockdowns, medical quarantines, or other circumstances that affect visiting.

We recommend that you read the California Department of Corrections and Rehabilitation’s detailed Visitation Guidebook before visiting an inmate because there is a ton of information in those 28 pages that will answer any questions you might have.

You can schedule a visit at Mule Creek State Prison by using the VPASS system. We highly recommend that you take advantage of this because not only will it guarantee you a spot in the visiting room, but it will also reduce your wait time. Scheduling a visit in advance is required for non-contact visits.

Getting Approved for a Visit

Before visiting an inmate at Mule Creek you must get on the approved visiting list. The first step is to ask the prisoner you want to visit to mail you a signed visitor questionnaire. Once you fill it out, mail the completed questionnaire to:

Mule Creek State Prison
Visiting Sergeant
PO Box 409099
Ione, CA 95640-9099

The prison will notify the inmate when you are approved, and it is their job to notify you. When you are approved you will be listed in the CDCR computer as being an approved visitor for that specific prisoner.

If you are denied, the prison will send you a letter explaining the reason for disapproval.

Contact, Non-Contact, and Family Visits

Most Mule Creek inmates are allowed contact visits. At a contact visit, the prisoner can sit with you in a large visiting room, and they may have limited physical contact with you.

Contact visits are restricted to five visitors at a time.

Inmates in ADSEG (Administrative Segregation) are only allowed non-contact visits, which take place in a separate visiting room, and the inmates and visitors are separated by a glass partition. You must have an appointment for a non-contact visit.

Some prisoners are eligible for family visits. These visits occur in private, apartment-like facilities on prison grounds and last approximately 30 to 40 hours. Prisoners with life sentences, convictions for sex offenses, or who under disciplinary restrictions are not eligible for family visits.

Family visits are restricted to approved visitors who are immediate family members of the prisoner, and they are restricted by availability; usually one visit every three to five months.
