This is the destination of Route 1-C at the Machu Picchu ruins. We entered the ruins a little after 7 am and slowly climbed for about an hour and a half. It was quite strenuous. The view of the ruins changed as we ascended, and the scenery was spectacular. Perhaps because of the time of day, there were hardly any people around, and at the Gate of the Sun, a caretaker took pictures for us and gave us a tour. Since this route is only accessible during the dry season, I highly recommend it.
