beautiful path along the Chezine between Sautron and Nantes

A beautiful walk, often with very few people. There are several possible paths in the park. It is possible to reach Nantes city center via the Chézine River.

The photo does not correspond to the bridge, which can be slippery depending on the season. But it is practical if you don't want to go uphill.

This is a handy way to avoid taking the technical path towards Orvault, or having to take a steep, developed path in the other direction. Beware of slippery bridges depending on the season.

The greenway project along the former railway line is the subject of much debate... and it's not about to stop! Ninety people attended the meeting organized by the municipality and the Erdre & Gesvres Community of Communes (CCEG) on Tuesday, April 15, 2025, at the Simone-de-Beauvoir Hall, regarding the development of the former railway line. For some participants, the greenway seems a long way off, as the road before construction begins. The will to implement this ambitious 26-km project is there, however. The users are numerous: walkers, hikers, people with reduced mobility, cyclists, mountain bikers, horseback riders (with or without a horse-drawn carriage), runners, farmers, heritage enthusiasts, hunters, local residents, rollerbladers, and simple strollers (with or without a stroller). Between Treillières and La Chapelle-sur-Erdre, commuters also use the road to get to work. It's not easy to accommodate all these people. Sylvain Lefeuvre, Vice President of the CCEG, in charge of mobility, recounted the discussions exchanged with partners in 2023: "We want to avoid conflicts of use. For our consultation, 881 responses were received, including 300 in Treillières. The population participated well," conceded the elected representative of Nort-sur-Erdre. "There is no procurement issue. Of the seventeen million allocated to the project, the State is granting us nine over six years. Its services will give the green light, but we won't be able to complete the project piecemeal. It will be all or nothing." Wilfried Braud, head of the Erdre & Gesvres mobility department, noted the participants' concerns about the quality of the road surface: "We need to find a sustainable solution that doesn't require major maintenance every ten years." A hard asphalt surface with a softer lane alongside seems to be the solution. There are also dual-lane lanes with grass in the middle. Local residents want this road to be off-limits to motorized vehicles and are wary of quads and dirt bikes. "We don't want boulevards," asserts this regular user of the promenade. Questions are being asked of the technical services. Studies are needed to regulate water management. Access for the fire department needs to be provided. What about the ancillary services, restrooms, the water point, and the rest area? And what about the heritage? The Fay-de-Bretagne shelter has been perfectly restored. Will the same be true for the one located opposite Treillières station? Users are aware of the lengthy process involved in a community project. They understand: patience is required for this greenway.
