This was an amazing experience. Our tour guide JC was incredibly smart, and had so much knowledge on the history of Peru, plants and wildlife, and current events. There wasn't a question he couldn't answer!
Something to note, the first day is easy, the second day is very difficult (high elevation, steep uphills, etc), the third day is easy, and the four day is no hiking at all.
I highly recommend this trek! Thanks for everything JC :)
