A very pleasant route accessible to all. The route is varied with water features throughout, whether it be the Sèvre river or the conches. The few sections on the road are quiet with very little traffic.

A pleasant, easy route. We did it as a family in beautiful (and hot) weather. The route is varied, alternating between paths along the Sèvres river and through fields. The few sections on roads are quiet with very little traffic.

Nice route. The end of the trail runs along the river, which is very pleasant and peaceful.
Some parts are busier than others, but most are very quiet.

A pleasant hike on a lovely nature trail. We had some difficulty finding the path during the first few kilometres, especially at the start. We slightly altered the route to use the chain ferry and therefore walked one or two kilometres on the other side of the Sèvre Niortaise. This was not a problem.

A beautiful hike, partly through marshland and partly along the Sèvre Niortaise river. There are a few stretches of road. A very pleasant route for exploring the area around Coulon, a beautiful village in the Poitevin marshes.

at the start of the walk, it was very nice, with canals and boats, but quite touristy. After that, it was just tarmac, tarmac and more tarmac. There were very few paths, and they were very poorly signposted. In short, we thought we had taken a cycle route, so no, I wouldn't recommend this walk

I think it's more of a cycling route; on foot, there are long stretches without much of interest in terms of scenery. I thought it would be more marshy. But there are still some very beautiful stretches through the fields and along the Sèvre.
Thanks anyway for the suggestion.

Completed at the end of March, few people around.
Hike completed using the app, mainly in the marshland area...
A beautiful, easy hike along the water's edge. The town of Coulon is well worth a visit.

Departure from Magné at 11 a.m. Nice path along the Sèvres Niortaise, arriving 1 hour and 15 minutes later in Coulon. Enjoyable meal on a terrace, la pigouille, then continued the hike. Very beautiful passage through the marshes, then country paths, pretty St. Macrine chapel, then Magné.
Total hike: 2 hours and 50 minutes at a leisurely pace.
Very pretty scenery.

A beautiful hike that allows you to see various landscapes of the marshland (small and large canals, wet meadows, poplar groves, villages, etc.).
You can start from Magné and stop for a break at a restaurant in Coulon after an hour to an hour and a half of walking.
