We pick the passengers up from their respective hotels at approximately 6:15am (depending on the train schedule) and transport them to the train station where they board the train to Aguas Calientes. From Aguas Calientes they take a bus up to Machu Picchu, where a guided tour of approximately two and a half hours takes place. Afterwards, they take the bus back down from Machu Picchu to Aguas Calientes where they will have time to eat lunch. Eventually they will take the train back to Cusco.
The trip to and from Aguas Calientes is done by train, although sometimes depending on availability this must be combined with a bus in the middle.
