I had the opportunity to participate in the 4 day Inca Trail trek in Peru and can honestly say that this experience blew my mind!!!
There were so many beautiful things to see along the way and every day there was some sort of Inca ruin or incredible mountain range view to keep your eyes occupied and build up the anticipation for the last day (Machu Picchu) so that you didn't get bored or worn out.
There was a lot of hiking and at some parts it was really hard but they took enough scheduled breaks to make it bearable and even enjoyable. They were patient if you needed to take your time but also had a faster guide up front in case you wanted to hike faster.
Every day we had breakfast lunch and dinner and lunch and dinner consisted of soup and then a huge meal usually a lot of rice and sauce, regardless it was all incredible! Gerson our tour guide was the best guide I've ever had so fun and patient!
I would highly recommend this trek, I am not an experienced hiker and I was able to do it so it's good for anyone who is in fair shape!
