Minnesota Correctional Facility – Willow River

A minimum-security (Level 1) state prison for men in Willow River, Minnesota — home to the Challenge Incarceration Program, the state's intensive boot-camp program for eligible men.

Overview

Minnesota Correctional Facility – Willow River (MCF-Willow River) is a state prison for men operated by the Minnesota Department of Corrections. It is in Willow River, in Pine County, in east-central Minnesota. The facility houses men in minimum custody (Level 1), the lowest of Minnesota’s five custody levels.

The Minnesota DOC assigns custody level based on factors that include sentence length, time remaining, and conduct, and a person’s custody level can change during incarceration. Because MCF-Willow River is a minimum-security facility, the population is generally made up of people near the end of a sentence or assigned to the Challenge Incarceration Program.

What Makes MCF-Willow River Different

MCF-Willow River is a minimum-security facility, and it is one of the sites for the Challenge Incarceration Program (CIP), Minnesota’s intensive, highly structured boot-camp program for eligible sentenced people. The men’s CIP operates here and at MCF-Togo; a women’s component is associated with MCF-Shakopee. CIP is a phased program: the first phase is a six-month residential phase at the facility that combines work, physical training, chemical-dependency treatment, education, and a strict daily schedule, followed by phases served under intensive supervision in the community. People who complete the program may qualify for an earlier supervised-release date. Because of the program’s structure, the day-to-day routine and the visiting arrangements at MCF-Willow River can differ from those at a general-population prison, so families confirm what applies to the specific person and phase before a first visit.

Visiting

The statewide MN DOC rules above — the approved visitor list, the dress code, ID, and item limits — apply at MCF-Willow River. The facility’s own arrangements:

Getting There and Parking

MCF-Willow River is at 86032 County Highway 61 in Willow River, in Pine County in east-central Minnesota. Willow River is just off Interstate 35, roughly midway between the Twin Cities to the south and Duluth to the northeast. The nearest large commercial airport is in the Minneapolis–St. Paul area to the south.

Parking is on site. Visitors confirm current entry procedures, the visitor-processing location, and what may be brought onto the grounds with the facility before arriving, because electronic devices and personal items are generally not permitted inside.

Nearby Services

Willow River is a small community with limited lodging and dining; additional options are in nearby Moose Lake to the northeast and Hinckley to the south, both along Interstate 35, with a wider range in the Duluth area to the northeast and the Twin Cities to the south. Emergency medical care is available regionally, with larger hospitals in the Duluth and Twin Cities areas. Visitors traveling a long distance generally find the most options for fuel, food, and overnight stays along the Interstate 35 corridor.

Mail

Minnesota does not deliver friends-and-family mail to the prison. Since November 1, 2024, the Minnesota DOC has personal mail processed off-site by a private vendor, TextBehind, which scans or photocopies each item and sends the copies to the facility (electronic delivery to the person’s tablet is also available for a fee). Mail sent directly to a Minnesota prison is returned to the sender.

Address personal mail this way:

First Name / Last Name, and OID number MCF-Willow River, Minnesota (do not abbreviate Minnesota) P.O. Box 247 Phoenix, MD 21131

Items missing a first and last name or the OID number are rejected, and envelopes without complete information are discarded unopened. Mail between two incarcerated people, pen-pal mail, and photo orders also go to the TextBehind address.

Some mail still goes directly to the facility, not to TextBehind: legal mail; published materials, books, and subscription renewals; business mail from courts, counties, child support, and other government agencies; and vital documents such as birth certificates, Social Security cards, and IDs (TextBehind forwards these to the facility). Legal mail is sent to the facility’s own address, and incarcerated people use the facility address as the return address on outgoing legal mail.

Verify the current mailing rules and the facility’s address before sending anything.
