Expedition Everest – Legend of the Forbidden Mountain, also known as Expedition Everest, is a steel roller coaster built by Vekoma at Disney's Animal Kingdom at the Walt Disney World Resort in Lake Buena Vista, Florida. The ride is themed around the Yeti protecting the Forbidden Mountain next to Mount Everest. It is the only roller coaster at Disney's Animal Kingdom, and the tallest roller coaster at any Disney theme park. The 2011 edition of Guinness World Records lists Expedition Everest as the most expensive roller coaster in the world,[2] a record the ride held until 2019 when Hagrid's Magical Creatures Motorbike Adventure at Universal Islands of Adventure opened.[3] Including sets and extras, its total cost was reported to be US$ 100 million for six years of planning and construction.[2][4] It is the tallest artificial mountain in all of the Walt Disney parks, and Disney's 18th mountain-themed attraction.[5] It is also the most recently opened attraction at Walt Disney World not based on pre-existing intellectual property.[6][7]
