All of our treks (the Inca Trail, Salkantay, Ausangate etc.) are moderately difficult, long and mountainous.
We highly recommend that you are relatively fit and acclimatised to altitude (a minimum of 2 days at altitude) before undertaking them.
During the months (or at the very least, one month) before your trip, you should take regular, moderate exercise. We want you to have an amazing experience and the fitter you are, the more enjoyable the treks will be.
