As other Magic Kingdom parks were built, they included their own similar version. At Walt Disney World the Rivers of America is similar to its California counterpart. At Disneyland Paris the Rivers of the Far West is home to Big Thunder Mountain. At Hong Kong Disneyland, there is no Frontierland, so the Imagineers merged the Rivers of America with the classic Adventureland Jungle Cruise attraction. Jungle river rafts now travel around the Rivers of Adventure, encountering similar situations as in the Jungle Cruise attraction, but on a much more open river and exposed to the elements of Adventureland. In the middle of the Rivers sits Tarzan's Treehouse, which can be reached by River Rafts.
