It is $15.99 for one trail, $25 for 2 trails which I would recommend and the forest is open until 10 for the last groups to go in I believe. Totally worth it and so much fun!
I don't remember the price, but it opens at 6pm till 11:00pm there are two houses. Anyone is welcome to attend, but be warned may be too intense for small children. If they feel really scared, you can request a back stage tour in what is called chicken road, and they will learn about the houses, and if they're up to it try again, I don't think you have to pay again for a new set of tickets. And what the escort guy will do is if they have a tour, they will ask the scare-actors to not scare if the child is still a bit nervous.
