They have a land at Knotts Berry Farm called Camp Snoopy. There are many rides for younger kids like a mini rollercoaster, a bouncer, a airplane ride like Dumbo ( you know, spins around in circles), several train rides around the park ( all though, be warned that one of the trains has a "robber" come in during the train ride, and another train travels through dark, bumpy caves). I remember having lot's of fun at Camp Snoopy when I was little, and parents can go on pretty much go on every Camp Snoopy ride. Camp Snoopy gets pretty crowded in the afternoon, so if you want to ride with little wait, get there early.
Places to eat: Mrs. Knott's Chicken and biscuits are to die for! They make them fresh every day, and many people come to Knott's just for the chicken, mashed potatoes, biscuits, and gravy ( like me
) There is one chicken dinner resturaunt outside the park, and there is one resturaunt in the Old West section. They have delicious funnel cakes and pies in the park too.
