Past Royan's port, this stage begins at Royan's Grande Conche beach. Head along the seafront on a lovely shaded cycle path.
The cycle route then threads between tracks and quiet roads to Meschers-sur-Gironde before reaching Talmont-sur-Gironde, an astonishing look-out post onto the estuary and part of the association of "Les Plus Beaux Villages de France". Caillaud Cliff and the "carrelet" square fishing nets suspended above the waters add to the atmosphere.
The stage continues via quiet, sometimes steep roads and tracks to Mortagne-sur-Gironde, a port well protected from the temperamental Gironde.
