Be careful what you ask for: "trail" in France generally means a poorly maintained, stony, rutted streambed. They followed the Roman notion of building in a straight line, up the hill, which means water runs straight down. No switchbacks or drainage improvements at all. And they do not prohibit ATVs (4-wheeled motorcycles). These are definitely not the forest floor, well engineered and maintained footpaths one sees in Germany or the US national parks. As I understand it, the local municipalities are responsible for maintenance but lack the necessary funds.
