Joaquín “El Chapo” Guzmán is held at the United States Penitentiary Administrative Maximum Facility, known as ADX Florence, in Fremont County, Colorado. It is the most restrictive prison in the federal system, and it is where he will spend the rest of his life. A federal jury in the Eastern District of New York convicted him on all ten counts of a superseding indictment in February 2019, and Judge Brian M. Cogan sentenced him that July to life in prison plus 30 years, with a $12.6 billion forfeiture order.1U.S. Immigration and Customs Enforcement.

Why He Was Sent to ADX Florence
Two Mexican jailbreaks explain the placement. In January 2001, Guzmán escaped from the high-security Puente Grande prison, reportedly smuggled out in a laundry cart, and stayed a fugitive for more than a decade. His second escape, in July 2015, was more elaborate: he left Altiplano maximum-security prison through a tunnel over a mile long that opened directly under the shower in his cell, complete with a rail system, a modified motorcycle, lighting, and ventilation. After his recapture in January 2016, Mexico extradited him to the United States on January 19, 2017.2U.S. Department of Justice.

The Charges Behind the Sentence
The trial ran three months. The jury convicted Guzmán on all ten counts, including running a continuing criminal enterprise, which itself covered 26 drug-related violations and a murder conspiracy, along with narcotics trafficking, using a firearm to further drug crimes, and money laundering conspiracy.3U.S. Department of Justice.

What ADX Florence Is
ADX Florence sits at 5880 Highway 67 South in Florence, Colorado.4Federal Bureau of Prisons. USP Florence ADMAX The Bureau of Prisons classifies it as administrative-security, a category built for inmates the government considers too dangerous or too much of an escape risk for any other facility. Its population reflects that: fellow inmates include Zacarias Moussaoui, tied to the September 11 attacks; Ramzi Yousef, convicted for the 1993 World Trade Center bombing; Richard Reid, the “Shoe Bomber”; and Umar Abdulmutallab, the “Underwear Bomber.” No inmate has ever escaped from ADX Florence.
Security Designed Against His Methods
The building is made of reinforced high-strength concrete engineered to resist tunneling, with steel rebar running through walls and floors. After a mile-long tunnel under a shower drain, that construction is a direct answer to his proven playbook. Interior corridors run on remote-operated steel doors. Motion sensors and acoustic monitoring cover the facility. There are no traditional windows, only narrow reinforced slits positioned so an inmate cannot identify his location or orientation inside the complex.
Life Inside the Cell
Guzmán spends 22 to 24 hours a day inside a single cell of roughly seven by twelve feet, about 84 square feet. The bed, desk, and stool are poured concrete, fixed in place so nothing can be moved, disassembled, or repurposed.4Federal Bureau of Prisons. USP Florence ADMAX The cell has its own shower and toilet. Light enters through one narrow slit that does not show the sky.
For about an hour a day, an inmate may leave for recreation in a deep concrete enclosure with a caged ceiling. Control-unit inmates use narrow empty spaces alone; general-population inmates are placed in individual cages inside a larger concrete yard, where they can see and speak to a few others but cannot touch them.5D.C.

Contact With the Outside World
Guzmán’s communications are governed by Special Administrative Measures. Under 28 CFR 501.3, the Attorney General can direct the Bureau of Prisons to restrict an inmate’s correspondence, phone calls, visits, and media contact when there is a substantial risk that his communications could produce serious harm.6eCFR. 28 CFR 501.3 – Prevention of Acts of Violence and Terrorism The same rule allows monitoring of attorney-client communications on reasonable suspicion that they could be used to facilitate terrorism or violence.
Visits are non-contact and take place in isolated rooms. Standard ADX inmates may receive up to five visits per month of up to seven hours each, and SAMs can cut that further.7Federal Bureau of Prisons.

Challenges and the Question of Transfer
Guzmán has challenged his conditions. In July 2024 he filed a federal complaint alleging that the isolation at ADX amounts to cruel and unusual punishment, citing untreated sinus, ear, nose, and throat pain, sleep deprivation caused by hot air blown into his cell at night, and little access to Spanish-speaking mental health staff. He was appointed pro bono counsel in December 2024, and the case was in discovery as of mid-2025 with no rulings on the merits.
His lawyers have also floated a transfer to Mexico under a 1977 prisoner-transfer treaty, and a Mexican federal court granted an injunction in 2024 directing a judge to examine whether repatriation is possible. The court did not order the Mexican government to act, and observers rate the odds of a transfer as extremely low. For now, and for the foreseeable future, the answer to where El Chapo is imprisoned stays the same: ADX Florence, Colorado.
