While the hike is achievable for most individuals with good physical fitness, we recommend acclimatizing to the altitude in Cusco before undertaking the journey. The minimum age requirement for the hike is 8 years old, and the maximum age limit is 60 years old. If you have any health concerns or medical conditions, please consult with your physician before joining the tour.
