According to Wikipedia: "The Palm Springs Aerial Tramway in Palm Springs, California, is the largest rotating aerial tramway in the world. It was opened in September 1963 as a way of getting from the floor of the Coachella Valley to relatively near the top of San Jacinto Peak and was constructed in rugged Chino Canyon. Before its construction, the only way to the top of the mountain was to hike a number of hours from Idyllwild."
