The famous "Raiders" scene of Indiana fleeing down a hill being chased by a band of warriors (really Hawaiians, whose bare behinds had to be darkened to erase tan lines), then jumping on a rope toward freedom, was filmed at the Rice Ranch. The rope is still there (or at least a version of it), dangling from the tree like a long monkey's tail. You can take the Kipu Ranch tour and swing for yourself!
Almost all visitors to Kaua‘i will drive up to see Wailua Falls. They will all take their turn at standing along the fence (if it's crowded) to look down upon this wonderous sight. However, I read about an adventurous hike to the bottom of the gorge to see it from a different perspective.
