You gotta get the water up there somehow

A water mill on the Swiss Family Robinson Treehouse in Adventureland. Opening along with the entire park in 1971, the treehouse is one of The Magic Kingdom's original attractions, standing six stories. It is based on the 1960 film Swiss Family Robinson. The original Disneyland attraction opened in 1962, but was closed and rethemed to Tarzan in 1999. The remaining swiss treehouses are in The Magic Kingdom, Tokyo Disneyland, and Disneyland Paris.
