Only for sporty MTB or gravel cardio outings, not at all for a relaxed ride. Be careful, after the metal barriers it's dredge soil (= mud in wet weather or rough, unrideable terrain when dry) and a monotonous high grass path. Personal opinion for local explorers, this western part of the canal is just a useless leg-breaker, prefer the secondary roads and paths in the marshes to the east to continue to be amazed.

An alternative to Eurovelo – but significantly uncomfortable. Caution first – there's a steep drop-off at the beginning. The path down to the canal isn't suitable for everyone. MTBs are great. Pushing is better with luggage and narrow tires. The view of the bridge is beautiful. There are many stones along the river, and some holes are encrusted with mud. Not so good with luggage. Perhaps too "exciting" for smaller children because the path is narrow and the water is very close. In retrospect, I would take the slightly longer but safer route on the Eurovelo. I got a flat tire here; there were lots of sharp stones.

The route is perfect: completely redone recently with a nice view from above (passage about 20m above the water).

Almost obligatory passage to cross the Charente, but it’s worth the detour
