Le Blanc is a small market town in the southern Indre department, straddling the River Creuse on the edge of the Brenne regional nature park. The town itself is pleasant and unhurried, with a medieval old quarter climbing up from the river and a lively Saturday market where local producers sell goat cheese, honey, and seasonal fruit.
The real reason to come here is the Brenne. Known as the "land of a thousand lakes," this network of medieval fish ponds and wetlands is one of the best birdwatching areas in France. The Maison de la Nature et de la Réserve in nearby Saint-Michel-en-Brenne is a good starting point, but you can also just drive the back roads with binoculars and a picnic. Herons, bitterns, and black-necked grebes are common; in autumn, migrating cranes pass through in large numbers.
In town, the Château de Naillac — a restored medieval keep above the Creuse — houses the local museum and gives good views across the valley. The church of Saint-Génitour, dating from the 12th century, anchors the old quarter.
Le Blanc makes a practical base for exploring the Brenne and the Creuse valley. The town has a handful of restaurants, a couple of supermarkets, and a campsite by the river. It is the sort of place where you come for a day and end up staying a week.
