Train travel · Normandy

Hi everyone,

I’m planning our very first trip to mainland France in January 2027. There’ll be 2 adults and 2 kids, and we’ll mostly be traveling by train.

Here’s our itinerary:

Paris Rouen (Normandy) Lyon Aix-les-Bains (with day trips to Annecy and Geneva) Saint-Gervais-les-Bains (with Chamonix and a day in Aosta) Back to Paris

Do you think this itinerary is well-balanced? Any tips, must-see spots, or mistakes to avoid for a first-time visit?

Thanks in advance for your advice! !
