Travel to Machu Picchu is almost too easy. Many people do the trip in a day out of Cusco, but it is worth two or three days, with overnights in Aguas Calientes and the Sacred Valley. The most common method is to hop on a train from Ollantaytambo to Aguas Calientes, which is a 20-minute bus trip from the ruins. Or you can do as the Incas did and walk the trail, which is a two- to four-day hike and a highlight for those who do it. Keep in mind that you need to book an Inca Trail trek six months ahead of time.
