Very smooth section of the canal with little traffic. Be careful of a section on the bridge with large cobblestones.

The toilets are large, you can take your bike inside but you have to disinfect it completely afterwards.

Gîte in a lock-keeper's house, between the two canals. The owner is lovely and attentive, making it a great place to spend the night on the Canal des Deux Mers.
