This route is fine if you’re just on a bike though some may find earlier sections narrow and difficult to navigate due to mooring ropes across the path. We did it with our dog trailer and found some sections precarious and too narrow for the trailer tbh.

Le Somail features remarkable buildings, including the inn, which has retained the same appearance as in 1773, the chapel, built between 1684 and 1693, and even an ice house. This supplied the inn and the shops of Le Somail with ice during the hot summer days of Languedoc. Everything is still in place! In the heart of the village is the Pont Saint-Marcel with its remarkable semi-circular shape, typical of the early bridges of the Canal du Midi. Nearby, one can still admire the guard's house, which also housed the postmen. On the banks of the canal, you can still see the old watering trough for the draft horses.
