Had a great trip on the Salkantay trek. It was very challenging from the beginning with the altitude but once my body got used to the height it was great.
It's a good fitness test and a great way to see Peru. The highlight for me was the gradual change in landscape from rolling hills, to snowy mountains and onto jungle. Everything was very well organized, food was great and the tea in the morning was a lovely way to wake up.Having a private area in each campsite made a big difference too, the areas were quiet and comfortable.
Looking forward to returning to do the Inca Trail next time!
