Inti Punku and Inca Drawbridge
If you have the time and the energy, head to the Caretaker’s Hut and hike up the Inca Trail, which arcs across the mountain slope to a high pass. It is about a one-hour walk to this pass, where there is a stone construction known as the Sun Gate or Inti Punku (2,720 meters)
After visiting Inti Punku, go back down the same trail to the path that branches off for the Caretaker’s Hut. Instead of continuing uphill to the Caretaker’s Hut continue along via the terraces along an alternative path that heads into the forest before arriving at a path with sheer cliff walls.
At one point, it even passes over a man-made ledge, like that found on the upper route at the Pisac ruins. The trail ends near a gap at the stone ledge, where the Inca evidently placed a drawbridge or a series of logs that could be withdrawn if necessary. The path past the drawbridge is overgrown and washed out, but it was an alternative route for reaching the Inca Trail back to Cusco.
