We walked this section in 2004, long before the section to the east. In those days we carried much bigger packs and knew much less about what we were doing, but it was impossible to get lost on the canal and it was certainly very flat walking.
Despite the numbers of pleasure boats going past, there were surprisingly few cafés along the canal and we had difficulty finding a camping ground that was not already full. (This was because of the housing shortage, due to the expansion of the aerospace industry in Toulouse.)
The canal and the countryside around it were beautiful, and so was the grand city of Toulouse, which we penetrated to its heart without leaving the canal.
