The Inca Bridge at Machu Picchu is a slim, cliff-cut passage that gives you a different sense of the site than the central ruins. It was part of a defensive back route carved into a sheer face at the western edge of the citadel.
The bridge itself is a short span of logs on a stone ledge, with a drop beneath it. In Inca times, those logs could be pulled back to seal the route. The engineering is small-scale but reads clearly on the ground: you can see exactly how the Inca intended it to work.
The walk to the bridge is a side trail from the main circuit and takes 30–40 minutes return. It is a flat path with a long drop to one side, so people with vertigo should think twice. The views over the Urubamba and the surrounding Andes are the payoff.
