I was thoroughly satisfied and exhausted at the end of the Inca Trail . My expectations in most cases were exceeded and I can not think of much at would improve the experience on the whole.
I really enjoyed the group of other couples we travelled with who were all of a similar age and fitness level to us which really made the pacing of the trek more fulfilling and enjoyable. I'm not sure if the group was deliberated selected for this reason but it was a great bunch of people to trek with.
The guide was excellent and always optimistic. The porters and food was great. Vegetarian option was a bit light and we were sometimes a bit hungry. Bring snacks! Overall excellent company I'd recommend!
