Grand Blockhaus de Batz-sur-Mer walks

The commune of Batz-sur-mer is located between the sea and salt marshes, on what was once, long ago, an island. A jagged ocean coastline contrasts with the peaceful landscapes of the salt marshes. Between the two lies countryside that was once used for food production but is now a mix of fallow land and horse pastures. And always in the background is the imposing tower of Saint-Guénolé.
