My experience hiking Machu Picchu with Inca Trail s was incredible. It was definitely physically demanding; I have never done such a challenging hike. The altitude alone was a little challenging, as oxygen seemed a little less readily available. But the guides are incredible knowledgable and kind- they help you go at whatever pace you need and encourage lots of rest and water breaks. Was it worth it? Absolutely . Finishing the first day hike up at the Sun Gate and being greeted with a gorgeous view of Machu Picchu was one of the most fulfilling feelings I´ve experienced. The trip is a little pricey, but worth every single penny. I would absolutely recommend it to everyone!.
