Jungle Cruise, formally named Jungle River Cruise, is a riverboat amusement ride located in the Adventureland themed section at various Disney theme parks worldwide. The attraction is a simulated riverboat cruise that travels along a waterway using a concealed guidance system through areas with Asian, African, and South American themes. Park guests board replica steam launches from a 1930s British explorers' lodge, and Audio-Animatronic jungle animals are displayed throughout the ride. A live Disney cast member acts as a tour guide and boat skipper that loosely follows a rehearsed script, providing passengers with a comedic narrative. The first installation of the ride was featured at Disneyland for its grand opening in 1955. A variety of changes were made over the years, including enhanced audio effects, updates to the storyline, and the removal of culturally-sensitive material. The installation at Hong Kong Disneyland features a significantly different storyline from the other parks and provides guests with three different language options, each with its own line queue. Following years of planning and delays, a film adaptation of the ride was released in the United States on July 30, 2021. Inspiration and design The project was planned by Disney to incorporate a jungle-themed ride into the list of attractions featured at Disneyland's grand opening in 1955. Sources of inspiration include a 1955 documentary called The African Lion from the True Life Adventures film series, as well as the 1951 adventure film The African Queen. Disney Imagineer Harper Goff referenced The African Queen frequently in his ideas and drew inspiration from the steamer depicted in the film for the ride vehicle design. Bill Evans was the Imagineer responsible for landscaping Disneyland and most of Walt Disney World. During the development of Jungle Cruise, he was given the somewhat complicated task of creating a realistic jungle on a limited budget. In addition to importing actual tropical plants, he incorporated "character plants" which have an exotic appearance despite not being exotic. He had used a well-known trick of uprooting local orange trees and replanting them upside-down, growing vines on the exposed roots. The ride's water clarity, known as turbidity, is controlled in a manner that obscures the boat's guidance system and other undesirable items like perches and mechanized platforms of the bathing Audio-Animatronic elephants and hippos. The waterway was originally dyed brown but was later changed to other colors: first to a green hue and later to
