Q'eswachaka Inca Bridge

Of the hundreds of rope bridges that held the Inca road network together, exactly one remains in use: Q'eswachaka, over the Apurímac canyon. It survives because four communities rebuild it entirely every June. They braid local grass fibre into cables as thick as an arm, cut the old bridge and drop it into the river, then assemble the new one over three days of collective work. The technique passes from parents to children and was never written down. The drive from Cusco is long — about four hours across the altiplano — and usually takes in the Pomacanchi lagoon and the Canincunca terraces on the way. You can cross the bridge.
