I went on this trip with my sister 4D/5N and I would definitely recommend to any of my friends and family.
It's great for challenging yourself and meeting people from all over the world, learning about Peruvian culture and history and eating great food. The guides are really wonderful as well! I have learned a lot about myself in the process and am thankful for this experience and to the group of people who joined my sister and I.
The views of Salkantay , and of the Andes mountain range is amazing and it is worth all of the effort and you get more than what you pay for.
