It was unclear whether the hiker died from the fall or from being stung Monday afternoon.
Phoenix Fire Department officials say they were able to rescue two other hikers from the Echo Canyon area of Camelback Mountain, and both were treated for bee stings.
According to officials, the survivors said they had to hide in some caves to avoid the bees until rescuers arrived.
Television footage showed a rescue helicopter lifting two hikers off the mountain separately and another person being carried off on a stretcher.
Some of the rescue workers wore white protective suits to keep them from being stung.
The names and ages of the hikers aren't immediately available.
