They have an interesting and informative tour available for a fair rate. I left with a head full of history about the penal system in Idaho, particularly the former death penalty. It's also a great place to take pictures and get a little creeped out by all the old buildings and execution chamber.

This was a fun place to go for a bit of history. A little pricey, but I know they have to do maintenance and keep it staffed. We went on the guided tour which was good.

Went for an after-hours self-guided tour. It was super cold, but a blast! Very cool facility. The docents were very nice and knowledgable. Definitely want to go back again (during daylight) for a more thorough tour.

I took the opportunity to photograph the Penitentiary on a photographers night. I was there day and night and it is cool. There are some restored buildings and some in decay. You can go through nearly all of the building including death row, which does have a vibe, I heard others mention it to. They have lots of historical pictures...

This place is a great look into Idaho history. It is nice and peaceful up there. You can also visit the Warden and Bishops house, I believe
