The Salkantay hike 4 days 3 nights is the short version of the classic Salkantay Trek, in this case the portion from Mollepata to Humantay Lake does it by bus instead of walking, the tour starts in Soraypampa and Humantay Lake to cross that same day the Salkantay Pass 15,000 fts to have a campsite in a beautiful place located close to the pass, the next days are the same than in the classic hike crossing the rain forest until arriving at Aguas Calientes to visit the incredible Machu Picchu on the last day.
