Inspired by Disney's 1999 animated film Tarzan, Tarzan's Treehouse replaced the venerable Swiss Family Treehouse that had been an Adventureland icon for 37 years. To enter the attraction, you climb a rustic staircase and cross a suspension bridge. From there, as they say, it's all downhill. Pages from Jane's sketchbook scattered about tell the Tarzan story and provide insights to the various rooms and levels of the treehouse. At the base of the tree is an interactive play area.
