The twelve-and-a-half minute ride begins at the Valley Station at 2,643 ft (806 m) and passes up a sheer mountain face through five life zones (biomes) on its way to the Mountain Station at 8,516 ft (2,596 m) above sea level. Travelers start in the Sonoran Desert and arrive at an alpine forest.
The floor of the 18-foot-diameter (5.5 m) aerial tram cars rotates constantly, making two complete revolutions throughout the duration of the journey so that the passengers can see in all directions without moving. With a maximum capacity of 80 passengers, it is the largest of the three rotating aerial trams in the US.
The view at the top can stretch northward for more than 200 mi (320 km) on a clear day, all the way to Mount Charleston north of Las Vegas, Nevada. Views to the east and west can stretch as far as 75 mi (121 km). California's Salton Sea is plainly visible to the southeast.
