Booked this months ago with my partner we weren't aware of what we were in for .. In saying that it was a great expereince.
The guides were great making sure we were doing ok and feeling fine the whole time. You did't have to race through the trek you can go your own pace, you don't want to go quick otherwise you will wear yourself out too quick.
The porters are so impressive !! I recommend getting one for your luggages It's well worth it as you don't want a lot of weight on your back while hiking.
The chef made beautiful food !!. The Inca Trek in the most rewarding thing you will do !! Enjoy.
