There are many attractions included. Everything else is free to see except the museum. Of the many attractions, the printer in the yard is probably the best. Now that printer is still available. National park staff will show you how to use it. Really great to see how Frankley worked here. Also allowed to see the haunted house, it was really cool when Franklin lived there. That little fire house, few people went to see it, but it was fun to think that Frank used it. Note that they close a smaller door than you expect. So don't wait until it's dark.
