A History of Adventureland at Disneyland.

Adventureland was one of the original four realms of Disneyland on opening day on July 17th, 1955. In early development it was known as True-Life Adventureland based on Walt Disney's True Life Adventure Documentary series. The only attraction in Adventureland on opening day was the Jungle Cruise. Walt's original concept for the attraction was to use real animals but ultimately decided to use robotic substitutes as real animals would not provide the consistent show Walt wanted. The idea of live animals in a Disney Theme Park would eventually return forty-three years later with the opening of Disney's Animal Kingdom The concept of a boat ride through the jungle was loosely based on the non-Disney film, The African Queen starring Humphrey Bogart. In contrast with what it eventually became, the original Jungle Cruise was meant to be taken as a serious almost nature documentary-style boat cruise through the jungle with more realistic looking animal robots. The layout of the Jungle Cruise was designed by Harper Goff who had designed the Nautilus for the Disney film based on Jules Verne's 20,000 Leagues Under The Sea. The exotic plant life needed to make the "Jungle" atmosphere convincing was the work of legendary Disney Park landscaper Bill Evans.

Not much would change in Adventureland during the first seven years of its existence, that would change in 1962 when Marc Davis joined WED Enterprises (Now known as Walt Disney Imagineering) and decided to inject some humor into the Jungle Cruise attraction with such beloved vignettes as the elephant bathing pool. The Swiss Family Robinson Treehouse based on the Disney film Swiss Family Robinson debuted that year as well in addition to the Tahitian Terrace restaurant. The following year saw the debut of the first Audio-Animatronics show "Walt Disney's Enchanted Tiki Room" which was a musical revue hosted and sung by animatronic birds, flowers and tiki masks with a title song by the Sherman Brothers. 1964 saw the addition of the "Trapped Safari" scene to the Jungle Cruise. Not much changed for the next two decades with the exception of some new scenes added to the Jungle Cruise in the mid-70s based on vignettes Marc Davis had designed for the version of the attraction in Walt Disney World's Magic Kingdom.

The first major changes in nearly thirty years appeared in Disneyland's Adventureland in 1993 with the replacement of the Tahitian Terrace restaurant with Aladdin's Oasis, based on the hit animated film of the previous year. The middle eastern style architecture did look quite bizarre juxtaposed with the more jungles of Africa-feel of the rest of the land. A major refurbishment of the Jungle Cruise saw the construction of a new building for the entrance queue designed under the supervision of the late Imagineer Eddie Sotto, the changing of the original pristine candy-striped boats with a more rugged and aged look and the re-routing of the jungle river to accommodate the building of the next major evolution of Adventureland with the opening of the Indiana Jones Adventure attraction two years later. On this attraction guests join archaeologist Indiana Jones in their Enhanced Motion Vehicles for an adventure in the legendary Temple of the Forbidden Eye.

In the mid-90s an entire musical number was edited out of Walt Disney's Enchanted Tiki Room due to shortening guest attention spans.

In 1999 The Swiss Family Robinson Treehouse was re-designed into Tarzan's Treehouse based on the animated film Tarzan from that year. Unlike its predecessor this treehouse felt more like a display in a Disney Store than a play area for guests to explore at their leisure.

Not much changed in Adventureland during the 2000s other than a major refurbishment of the Enchanted Tiki Room which re-opened in 2005 for Disneyland's Fiftieth Anniversary and a brief promotional push in the Summer of 2008 for the film, Indiana Jones and The Kingdom Of The Crystal Skull.

In 2018 the always out of place looking Aladdin's Oasis closed to be transformed into the Tiki Room themed "Tropical Hideaway". In 2021 on the heels of a global pandemic that had closed the park for an extended period for the first time in its history, it was announced the Jungle Cruise would be replacing the scenes near the end of the attraction which were based on outdated stereotypes of native peoples from mid-20th century Hollywood with a vignette of a group of monkeys commandeering a boat and the Trader Sam character at the end of the attraction was replaced with a mock improvised gift shop. Tarzan's Treehouse finally closed in 2021 was re-designed by a creative team of Imagineers led by Kim Irvine into the "Adventureland Treehouse" which opened in 2023 and largely restored the adventurous nature of the original Swiss Family Robinson Treehouse. Even more amazingly this was one of the few attractions greenlit under former Disney CEO Bob Iger which did not feature any tie-in with a movie or other intellectual property, a concept largely frowned upon during Iger's tenure as CEO.
