First off I want to say Caesar was an incredible tour guide. Showing and teaching us about their culture.
This trail is a good way to test your physical and mental ability. The porters were outstanding, and was amazed how fast they could move through the mountains in any weather. The cook also supplied us with incredible tasting food. The trail and altitude was a bit tough, but once you make it to the inca sites its definitely worth the struggle.
I recommend that you drink lots of coco tea, and bring walking stick to aid you with your adventure. Awesome trail! .
