Although I had no expectation, this hiking trip was the best of my life ! The people I met were great, the guides were above all very helpful and friendly plus the sceneries were amazing. At the same time I learned a lot about the Inca culture. I felt very connected to the earth and spiritual at the same time while doing this trip.
If you plan to make this trip, I would definitely advise you to prepare yourself physically as the rhythm and speed of the hiking are intense. Also, as you get higher and higher, you have less oxygen but still have to go. This can be hard for some people.
