On the cliffs at Pointe au Sel, between St-Leu and Étang-Salé-les-Bains, this museum, housed in an old salt warehouse, traces the local salt-harvesting history. It's flanked by salt evaporation ponds. After visiting the museum, follow the path that leads to La Caverne (no sign), a large, wonderful rock pool with turquoise waters only known to locals. It's ideal for splashing about, sunbathing or picnicking.
