The outdoor entrance to the Fountain of Youth is the Waikapala'e Wet Cave on the north shore of Kauai. Analogous to this movie's magical watery passage to the Fountain of Youth, the cave holds a real submerged (depending on water level) passage, through which explorers can travel, in order to reach an isolated chamber known as "The Blue Room". Some Hawaiians tell of an actual pirate treasure found hidden in "The Blue Room" by the original discoverers. The pirate treasure (if it ever existed) is gone, but the cave and chamber remain a natural treasure, still accessible to intrepid explorers.
