During Halloween time on weekends Knotts Berry Farm turns Camp Snoopy into Camp Spooky. Kids 3-11 can dress up....my little one dressed up as a pirate! We just went Saturday. They hand out trick-or-treat bags and the kids walk to certain stations for candy. They have a craft tables for the kids and "Haunted Harvest" maze (which my child didn't want to try) and a Great Pumpkin Maze....my son did want to try and liked it.
What is great is seeing the characters dress up in costumes too. The only character my son would take a picture with was Snoopy dressed as Dracula. My son loved the rides (he is going on 4 yrs old). His favorite was Red Baron and Snoopy Bounce.
