France is the country most British travellers think they already know, which is exactly why a well-planned trip surprises. The difference is in the detail: a Provençal farmhouse with a table under the plane trees, a Saint-Émilion estate that opens its cellars privately, a Paris hotel on a quiet street in the Marais rather than a busy boulevard.
Most trips combine Paris with one region. The fast train makes Provence a comfortable day of travel, and Nice has direct flights home for the Riviera. In winter the Alps take over, with chalets in Courchevel, Méribel and Val d'Isère, and Chamonix for serious mountains.
The honest caveat is high summer in the south. The Riviera in late July and August is crowded, the coast road jams and prices peak. June and September bring the same sea and warmth with far more space.
