It is really easy to get the public bus here from Cuzco. Walk through the market once you get off the bus and sample the local fare, before either climbing the hill to the ruins, or catching a taxi.
If you get a taxi, ask them to pick you up at a different point to where you get dropped off, you can then do a nice, but easy walk around. The terraces are stunning and you feel like you are on top of the world.
About 1 hour from Cuzco
