1. Hiking the Inca Trail is the only way to get to Machu Picchu.
Thousands of travelers visit Machu Picchu every day, and only a fraction of these visitors got there via the Inca Trail. After hiking for four days through sparsely populated mountains, many Inca Trail hikers are surprised to find a small but bustling modern town at the base of the mountain, complete with a crowded train station. The Peruvian train system is extensive, and has been shuttling travelers to the base of Machu Picchu mountain from the Sacred Valley for years.
