How much would it cost for adults and kids?

20$ adults 15$kids

Adults: $20, kids 3-12: $15. Add an additional $4 to either if you want to see the planetarium as well! (Source: website)

It has been awhile since I have been to the Virginia Living Museum. I cannot remember just how much my sister paid for herself, and me. But my recommendation would be to either call the Virginia Living Museum, or try to Google the Virginia Living Museum /prices, and hopefully this is helpful for you.

You can save on Admission if you are military or have AAA membership. AAA membership will save you$2 off each ticket
