Since being acquired by Cedar Fair, the park has seen an aggressive shift towards thrill rides, with the construction of a number of large roller coasters and the addition of a record-breaking Shoot-the-Chutes ride named Perilous Plunge. Perilous Plunge had the record of being the tallest and steepest water ride in the world until September 2012 when it was closed and removed. Also, in 2013, Knott's Berry Farm announced that the most popular ride at the park, the Timber Mountain Log Ride, would be closed for a major five-month refurbishment, led by Garner Holt Productions, Inc.
