The Safari gondola (cableway) at Kolmården Wildlife Park. Without windows, you move slowly over the lion enclosure, the savanha, the scandinavian forests, the highlands and the african wilddogs.
It must be like having one of those "rotation sushi" conveyor belts that you get at Japanese restaurants for the lions but with the added frustration of never being able to reach out and get a snack. These cats must get quite irritated by it, if I was a lion I certainly would.
