A slide on a natural toboggan goes wrong

In Cusco, just above the city, lies the Inca site of Sacsayhuamán, famous for its huge, perfectly-fitted stones. But next to the ruins, there's also a more playful curiosity: an erosion-polished rock called Rodadero, used as a natural slide. Local children have been playing on it for a long time, and travellers also try their luck. You sit at the top, let yourself slide and end up laughing at the bottom.
