The most popular and easiest way to get to Macu Picchu is by train. You can either take it in Cusco city or in the last train station, which we recommend, at Ollantaytambo.
The other way to get from Cusco to Machu Picchu is to walk as part of a multi-day Machu Picchu tour. Thousands of people hike to Machu Picchu each year.
