It was a very intense experience, for me. As I just simply set foot on there, I felt some tingling sensation on the ground, like it was all still too alive even though the prisoners were no longer there.
We went into the cell house and we had a guided audio tour where they showed different parts of the island. It was VERY cold though, so when you go, especially during the summer, BRING COATS and possibly gloves and scarf.
You see in all the cells how the prisoners lived and they explain everything that took place there, the attempted escapes, the shootings, everything.
And of course, there was the room for all the misbehaving prisoners, they would put them in these dark silent cells and keep them in there for months...possibly years.
You could go inside many of the cells as well.
I personally felt so much energy there, not just because of the people alive, but the place just by itself, it felt so alive...
