Would you recommend visiting the Salem Witch Museum or the Witch House? (With 3 school aged kids - only have time to do one place)

With little kids I would do the witch museum. I think there is more to keep younger kids interested. But my teenager loved the witch house.

Yes, it has a lot of historical information.

I would probably do the Salem witch museum. The witch house is small. It does not take very much time though.. you may be able to do both. The witch museum is closed until after holidays
