Walking pass the Arquejols Viaduct; it was quite an imposing structure. The viaduct is part of the now disused Le Puy to Langogne railway line. Passenger traffic ceased on the line in 1939 and freight traffic came to an end in 1988.
The Chemin de Stevenson passes below the viaduct before ascending a step track to a point above the railway line.
