Tucked away at the foot of the cliffs between Monaco and Cap Martin, you'll find the Plage du Buse, a real local's secret. This quiet pebble and gravel beach boasts stunningly clear, turquoise water perfect for a refreshing swim or some snorkeling. It's a bit of a walk down a number of stairs from the nearby train station car park—about a five-minute descent—but that's what keeps it so peaceful and preserved. Don't expect a lot of amenities, just a shower and a small snack bar, which adds to its unspoiled charm.
