We had an amazing experience doing the four day Inca Trail to Machu Picchu.
Ate first the only slightly negative thing was the organisation before the start of the trek. we just have been informed one day before our hike to meet up in the evening. First the manager itself came by and not the guide and therefore we didnt receive all the information.
Besides that, the Trail itself was awesome. Our guide was really nice and cared about us and the food was amazing and i really didnt expect that. Also the organisation during the trek and the equipment (tent, sleeping bag) was very good.
I therefore can really recommend doing the inca Trail.
