I visited this WHS in February 2014. Since I was based in Carcassonne, I first enjoyed an afternoon walk by the juniper tree-lined canal with its bridges and locks near Carcassonne. Later on I visited the Canal du Briennes near Toulouse and pretty much had the same experience there too. For a change, I opted to visit the Grand Bassin of Castelnaudary where there were much more boats, a small river island and a different view of the Canal du Midi. At Castelnaudary, I found an informative explanation of why the Canal is so important as an engineering feat and as a WHS. I finished off my visit with a great Cassoulet at Le Tirou, the number one restaurant in town if you want to try the best cassoulet ever!
