What attraction is known for the "Na'vi River Journey"?

The "Na'vi River Journey" is an attraction that immerses guests in the bioluminescent world of Pandora, inspired by the film "Avatar." It offers a tranquil boat ride through a vibrant rainforest, showcasing stunning visual effects and animatronic figures that depict the Na'vi culture and environment.

While "Avatar Flight of Passage" is another attraction in the same themed area and allows guests to experience the sensation of flight on the back of a banshee, it is specifically not the one associated with the Na'vi River Journey. The other attractions listed, such as Space Mountain, Expedition Everest, and The Haunted Mansion, are distinct in their themes and experiences, not related to the "Na'vi River Journey." This further confirms that the correct answer is linked directly to an experience set within the world created in "Avatar," which is exclusive to the designated attractions within Disney's Animal Kingdom.
