With the exception of Sierra Sidewinder and Timberline Twister, the rides are relatively tame. Knott's Berry Farm maintained a completely private police force, vested with full police powers, and overseen by park management. The park formerly featured a 5th area called the Wild Water Wilderness. Thank god most reviews were way off base we had a blast. The Xcelerator is a 50s themed roller coaster that will accelerate you from 0 to 82 miles per hour in 23 . That's what maintenance said. $34.99. [CDATA[// >
