I did the four day trek and it was amazing ! Our guide, Victor, was friendly and knowledgeable about Peru, the Incas and the culture. The food was amazing and you can drink all the coca tea you want !
The ascent to the Salkantay pass is difficult but very rewarding and Victor encouraged us the entire way. Humantay lake is an awesome side trip and not to be missed. The jungle section of the hike is amazing with lovely birds and flowers and amazing views of the river.
I would recommend this trip to anyone who loves the outdoors and wants to experience a new and amazing culture !
