Réserve Naturelle de la Truchère-Ratenelle
Forty minutes south of Chalon lies one of the most surreal landscapes in inland France — a nature reserve sheltering ancient inland sand dunes, oxbow lakes and rare orchid meadows. Most visitors to Burgundy never hear of it, which makes the experience feel like a private discovery.
The Dunes and Lakes
The dunes at La Truchère rise up to 10 metres, formed by Saône floodwaters depositing sand over millennia. Walking the marked trail through pine and birch onto the open dune crests feels genuinely otherworldly for landlocked Burgundy.
The étangs (shallow lakes) alongside the dunes host great crested grebes, grey herons and, in spring, breeding European tree frogs whose chorus fills the air from March onwards.
Wildlife and Wildflowers
The reserve protects over 30 species of wild orchid, including the rare lizard orchid, best seen in May and June along the meadow trails.
Roe deer are commonly spotted at dawn and dusk, and the reserve is one of the few Burgundian sites where you can reliably see European kingfishers perched over the slow river channels.
