This full-day excursion from Cusco will allow you to access the Andes to see a picturesque lagoon at high altitude with only a small amount of moderate difficulty hiking. Go to the path that leads to the Humantay Lagoon or rent a horse (additional cost). Along the way, look for views of iconic Andean peaks, including Salkantay. In the lagoon, make an offering to the mountain spirits and take a bath, if you dare.
