Southern France's Occitanie region packs an enormous amount into one corner of the map: red-brick cathedral cities, hilltop medieval villages, Roman-era wine country and the windswept wetlands of the Camargue where white horses and flamingos share the salt flats. A new 12-day, 11-night itinerary from French Country Adventures threads those highlights together with a deliberate slow-travel philosophy: tours are capped at six people, and the guiding mantra is "when you do less, you experience more."

The route starts in Albi, the UNESCO-listed "Red City" on the Tarn river. Its huge Sainte-Cécile Cathedral is the world's largest brick cathedral — plain on the outside, riotously colourful within, with frescoes and trompe-l'oeil covering nearly every surface. Next door, the Palais de la Berbie holds the biggest public collection of Toulouse-Lautrec works anywhere, and its gardens look out over the river.

From there the tour moves through the fortified hilltop villages the Tarn is known for: Cordes-sur-Ciel, founded in 1222 and often floating above morning mist; tiny walled Puycelsi; and, itinerary permitting, Najac with its royal fortress above the Aveyron Gorge and the château village of Belcastel. Food and craft stops follow — pink garlic at Lautrec, wine tastings in Gaillac where viticulture dates back to Roman Gaul — with long local lunches treated as part of the education, not a break from it.

Around day seven the scenery shifts south to Aigues Mortes, Louis IX's perfectly walled medieval port built as a Crusade launch point. It becomes the base for exploring nearby salt marshes and fleur de sel production, plus a trip to elegant Uzès and its celebrated market. The finale is the Camargue itself: lagoons, salt flats and beaches, home to flamingos, the famous white horses and the Gardians, the region's traditional horsemen.

The host, Sue Aran, is American-born and has lived in south-west France for 20 years, working as a guide, writer and photographer. Every restaurant, hotel and artisan on the route has been tried by her personally, which is the kind of curation that matters on a trip this small and unhurried.

Why it's worth a look: Occitanie is easy to rush through — the draw of big names like Albi and the Pont du Gard pulls people onto fast itineraries — but the region's real character lives in its village fêtes, night markets, Armagnac traditions and food culture, from cassoulet and Aligot to Roquefort, seafood and the wines of Corbières, Minervois, Pic Saint-Loup and Picpoul de Pinet. A six-person tour built around lingering is aimed squarely at travellers who'd rather meet a knife-maker in Lautrec than tick a fourth cathedral.
