On Saturday, October 29, 2016 from 10 AM to 5 PM there is a Halloween Family Faire for all ages in Woodland Hills. Admission and parking are both free. There will be free entertainment and activities, including a kids costume parade and free bike repair.
There will also be several games and activities where you need to buy a ticket, including face painting, pumpkin decorating, and carnival style games. Tickets are $1 each or 25 for $20. For a family, that could break down to just a few dollars per person.
