Frightened Felons

FRIGHTENED FELONS XII, 12x the Terror! Frightened Felons will return in 2021!

While we are disappointed that Frightened Felons, our annual Halloween spectacle, is not taking place this year, we are excited to offer visitors a different Halloween experience on a smaller scale that will allow guests to soak in the naturally spooky atmosphere of the Old Idaho Penitentiary. From premiere screenings of Paranormal Prison, the new horror film recently shot at the site, to Sweet ‘N Spooky, an opportunity to trick or treat within the penitentiary, there is something for everyone this year while we wait for Frightened Felons to return!

Check our our Events page for information on all of these events. Tickets are on sale now!


We invite you to tour the site at night and dare to enter Terror in Cell Block 4, the only haunted cell house in Boise (expanded even more this year with more frights per cell!). With special performances of the Zombie “Thriller” Dance, ghost story presentations, costume contests with cash prizes, actors portraying inmates of the past, Old Pen mugshots and photo ops, photos with our historic hearse and undertaker, music, games, scavenger hunt, food trucks, coffee and hot cocoa! Beer and wine will be available on Adult Night.

18+ Only, ID Required at the Door. This event is rain or shine, dress accordingly! Masks are not recommended. Staff may ask you to remove your mask in certain areas due to visibility concerns and safety hazard.

Some accessories (prop weaponry, etc.) may not be allowed inside. Costumes deemed inappropriate are subject to staff discretion and may result in denial on entry. Please reach out to us beforehand for specific questions about this policy, or your costume.
