I saw this while looking up things to do in Philadelphia and immediately added it to the to-do list during one of my upcoming trips. I decided to go on an early Sunday afternoon. There is lots of street parking available in the immediate area...but its probably best to stick to the main streets (Fairmount and Corinthian Avenues...). Once you get into the side residential streets, the signs there mention "permit" which made me a bit nervous. I know some neighborhoods require residential permits to park on the streets and I didn't want to take the chance. Admission prices were $21 for adults and $17 for childen. Children under 6 are free. (Online prices...not sure if was more at the ticket window) After entering the front, you pick up your audio device. A small device with headphones that you can select various numbers marked throughout the penitentiary that will tell you a bit about that area or exhibit. I hope at some point, they would offer an app or online guide where you can use your own phone and earphones for this...the device provided is very dated and comes with wired over the head headphones which can get in the way if you are carrying items, a camera for example. The penitentiary itself was great. While the audio device was cumbersome at times, the information provided throughout the self-tour was impressive. It is very well-paced and guides you through the main areas before letting you know the formal tour is over and your are free to explore. There are many smaller areas and exhibits throughout the penitentiary with wonderful little details about prison life at that time. A must for any history or architect buff. One of the larger areas is the prison yard which leads into an indoor exhibit focusing on the impact of prison reform and overall effectiveness of the various prison philosophy. I like how they included something relevant to modern-times and its impact on today's society. It really stresse that we, as a nation, can do a lot better. I usually get through museums pretty quick...reading the exhibits while taking lots of photos. This took me about 2 hours to get through most of the areas. There were certain areas I was less interesting in that I didn't read or listen to the entire description. So give yourself time if you plan to see everything...also wear comfortable shoes as there is quite a bit of walking. There is a small gift shop toward the end of the tour with clothes, mugs, books...etc...what you'd expect to find in most gift shops. There is also a bathroom trailer as you exit...very clean actually. All staff I encountered were friendly and polite. As for children...some older children may be interested in the history and stories of the prison...but there really isn't much "to-do" for younger children. The entire tour is on one level throughout the cell blocks, prison yard and other sub-areas...there arent any stairs except for one view from the upper cell block level. The penitentiary is in walkable distance to the Philadelphia Museum of Art, Rocky Statue and Steps and surrounding park. There are also some nice eating options along Fairmount Avenue which leads right into the park...not a bad idea to make a day trip to include the penitentiary, food stop and park.
