Project Amazon
Project Amazon was one of the most ambitious developments in Chessington World of Adventures’ recent history. Aimed at expanding the park’s attraction lineup and overall footprint, the project saw the transformation of a former picnic field into a brand-new themed land. Initially teased during consultations with residents in May 2021, the plans promised a multi-ride expansion unlike anything the park had attempted in over a decade.
Submitted formally in August 2021 under the codename Project Amazon, the proposals detailed three brand-new attractions: a roller coaster and two flat rides. Though early documents remained vague regarding the land’s theme, speculation quickly mounted due to the layout of paths and attractions. Many observers connected the dots and suspected that the land would be themed to the Jumanji film franchise—a theory later confirmed by the park.
After gaining planning approval in January 2022, construction began just one month later. Despite tight deadlines, the project stayed largely on track thanks to careful coordination between Chessington and its partners. The result was The World of Jumanji—a fully themed immersive environment based on Sony Pictures’ Jumanji universe. Featuring striking jungle theming, iconic visual elements from the films, and a soundtrack inspired by the movies, the area marked a bold new direction for the park.
The star attraction was Mandrill Mayhem, Chessington’s first inverting roller coaster. Alongside it came two thrilling flat rides, Mamba Strike and Ostrich Stampede, all tied together within a lush jungle setting. The World of Jumanji officially opened to the public in 2023, backed by a major marketing campaign. Project Amazon delivered not just new rides, but an entirely new world, expanding the park’s offering for thrill-seekers and families alike, and marking a major step forward in Chessington’s evolution.
