Hello! I will do the Inka trail in the end of June, and before that I will spend a week in and around Cusco. After the Inka Trail I would like to do a Vinicunca Rainbow mountain trek, not a one day hike but one that is at least two days long, or more. How easy is it to find a trek like that, for the beginning of July, while I’m in Cusco? If booked directly at a travel agent in Cusco, how much do the treks cost? Which agency would you recommend?
