The Bayonne - Saint-Jean-Pied-de-Port railway is a French 52-kilometre long railway line, that connects the Bayonne to Saint-Jean-Pied-de-Port, running through the foothills of the Pyrenees.

It continues through valleys within the Pyrenees until it reaches Saint-Jean-Pied-de-Port station, its south-eastern terminus.

As of 2014 no trains run south from Cambo-les-Bains and a rail replacement bus service is used from this station onwards to SJPP.

At one point, where the line crosses the river on a truss bridge, the ballast has been washed away over a distance of about 30 feet and the rail and crossties are suspended in mid-air.

There is a collection of driftwood at this point; evidence of flood damage (probably at this location: 43.256303, -1.320315).
