I just had my 1st grader there 3 days ago as part of a school sponsered field trip. He loved it.
Our tour guide was an elementary school kid who was volunteering and she brought an "assistant" who was about 6 years old. Obviously these kids are well trained and well aware of the history.
Some areas of the jail might be considered a little scary for younger children, such as the solitary confinement area and the gallows. Hope this helps.
