The impressively deep amphitheater-like terracing of Moray , reached via the small town of Maras , is a fascinating spectacle. Different levels of concentric terraces are carved into a huge earthen bowl, each layer of which has its own micro-climate, according to how deep into the bowl it is. For this reason, some theorize that the Incas used them as a kind of laboratory to determine the optimal conditions for growing crops of each species. There are three bowls, one of which has been planted with various crops as a kind of living museum.
Though refreshingly off the beaten path, this site is not challenging to reach. You can take any transportation bound between Urubamba and Cuzco via Chinchero and ask to be let off at the Maras/Moray turnoff. Taxis usually wait at this turnoff to take tourists to Moray and back for around S30, or both Moray and Salinas and back to the turnoff for around S50.
