Free if you become a Friend of the National Park. It's around $60 for the family.
From what i remember earlier in the month. it was about $15-16 person. I know it's a little on the pricey side. Includes museum and the cyclorama(?) The cyclorama was good though. Caught my 10 year old son's attention and kept it. He talked about it all the way home.
We bought a package deal for 3 different venues at the Jenny Wade House for under 10 dollars a museum.
