There are several ways to visit Machu Picchu, including taking a train or hiking one of the alternative trails to Aguas Calientes – the town in the valley below Machu Picchu. But none of these alternatives are as popular and arguably as impressive as the Inca Trail trek to Machu Picchu. Famed as Peru's most famous trek and one of the world's most iconic trekking experiences, the Classic Inca Trek to Machu Picchu offers an awe-inspiring combination of subtropical Andes mountain environments, including the forest of clouds, alpine tundra and jungle, Inca Archaeological Sites; some of them are worth visiting! The “classic” route usually ends on a 4D / 3N route, but can also be extended by one day or shortened to a 2D / 1N hike on the “short Inca route”. It is also possible to combine the Salkantay trek with the classic route for an epic and challenging 7D/6N adventure.
