Without a doubt, take the Vistadom train when heading to Machu Picchu. It's a fun, scenic ride which really gets you ready for the experience. It ltravels from Ollantaytambo in the Scared Valley to the town that sits below Machu Picchu. It takes about two hours and so enjoyable. Load you ipod with some chill Peruvian tunes, sit back and enjoy the views!
