[1] This Inca Bridge is a part of a mountain trail that heads west from Machu Picchu.

[2] A twenty-foot gap was left in this section of the carved cliff edge,[3] over a 1,900-foot drop,[3] that could be bridged with two tree trunks, otherwise leaving the trail impassable to outsiders.

[4] This Inca Bridge was an ancient Inca grass rope bridge[5] out of Machu Picchu, crossing the Urubamba River southeast of Cusco in the Pongo de Mainique.

The Mawk'a Chaka (Quechua for "old bridge", hispanicized spelling Mauca Chaca), an historic suspension bridge over the Apurímac River, near Quebrada Honda, the town of Curahuasi and the Cconoc thermal baths (13°31′46″S 72°38′35″W / 13.52944°S 72.64306°W / -13.52944; -72.64306), disappeared by the end of the 19th century after 300 years of service.

Local organizations are planning to rebuild the bridge with its access roads and tunnels to serve the hiking community and provide a view of the gorge.
