Isthmus of Fitzcarrald, Land bridge in Madre de Dios, Peru.
The Isthmus of Fitzcarrald is a land bridge in the Andes that connects the Urubamba River basin to the Madre de Dios River basin. The passage stretches about 11 kilometers through mountainous terrain and crosses a particularly steep hill with a sharp incline.
The crossing was discovered in 1893 by Carlos Fermin Fitzcarrald, who sought a practical way to transport rubber between different river basins. This discovery opened a new trade route during the Amazon rubber boom in South America.
Local communities view this crossing as a vital link between two river regions, and the route reflects centuries of indigenous knowledge about mountain passages.
The route follows an unpaved path that becomes difficult in rain and is typically crossed using mules for transport. Visitors should bring sturdy shoes and be in good physical shape, as the slope is taxing.
In 1895, an entire steamboat called the Contamana was dismantled and carried across the isthmus to prove the route could work for commerce. This remarkable feat showed how determined early traders were to make the passage viable for moving goods between river systems.
