Days 1–3: Paris → Day 4: Versailles or Loire Valley → Day 5: Avignon & Provence → Day 6: Nice → Day 7: French Riviera & Departure. The TGV takes about 2 hours 40 minutes from Paris to Avignon and about 3 hours from Avignon to Nice, with seamless high-speed rail connections throughout.
For a focus on royal history, choose the Palace of Versailles—spend half a day to a full day exploring the Hall of Mirrors and the French gardens. For castle scenery, take a TGV to the Loire Valley to see Château de Chambord and Château de Chenonceau. You can also return to Paris the same day and stay overnight there.
In the morning, visit the Palais des Papes and the Pont d’Avignon in Avignon. In the afternoon, hire a private car or join a half-day tour to the Luberon region to see lavender fields (best in mid-June to mid-July), the stone village of Gordes, and the spring town of Fontaine-de-Vaucluse, experiencing the sunshine and hilltop charm of southern France.
After arriving in Nice by train, explore the Old Town and Cours Saleya Market, stroll along the Promenade des Anglais, and climb up to Castle Hill in the evening for views over the Bay of Angels. If you have extra time, consider adding a half-day trip to Monaco or the cliffside town of Èze.
Spend the morning at Nice Beach or take a short trip to Cannes, then depart from Nice Airport in the afternoon. If you have a longer holiday, add an extra day in either Provence or the French Riviera to slow the pace.
