Obviously, not appropriate for the tots, but if you are looking for something actually scary, here’s a couple haunted houses and Halloween attractions near  Spartanburg. I personally don’t pay money to be scared by zombies, so you won’t find any personal comments here. Some of these attractions clearly state what ages they target, others are less clear so we recommend looking at the photo gallery on the websites linked and/or calling the attraction to evaluate whether it’s too scary for your older kids (or you).
You can find our list of Halloween events appropriate for all ages on our trick-or-treating in Spartanburg list.
