Knott's Pacific Pavilion opened June 1986 in the Roaring 20's themed area with Splashdance '86, a water show with 2 trained dolphins and 1 sea lion. Shows ended on Oct. 8, 1998, preparing for a new attraction which opened in 2000, the Perilous Plunge.

Yes, Knott's Berry Farm once had a popular dolphin attraction known as the "Pacific Pavilion." During the 1970s and into the early 1980s, the park featured a stadium where guests could watch bottlenose dolphins perform tricks and educational demonstrations. This was part of a broader trend in the theme park industry during that era to incorporate live animal shows to compete with venues like SeaWorld. However, as public sentiment regarding the ethics of keeping marine mammals in captivity began to shift, and as the park's focus moved toward high-thrill roller coasters and its traditional "Ghost Town" heritage, the dolphin show was eventually phased out. The stadium area was later repurposed for various other live performances and seasonal events. Today, there are no live dolphins or large marine mammal exhibits at Knott's Berry Farm, as the park has fully leaned into its identity as a premier destination for world-class thrill rides like GhostRider and Xcelerator, as well as its world-famous Knott's Scary Farm Halloween event, which remains its biggest annual draw.
