Day 1 — Paris: start, car pickup, and an easy entry into the trip
🚗 Start of the day — CDG airport or one of Paris’s major stations, finish — an overnight stay on the western edge of Paris or at an official campsite. Driving distance for the day is small: ≈25–45 km, with net driving time usually 1–1.5 hours because of city traffic. Main stops: car rental pickup point, a P+R by RER/Transilien in Île-de-France for a trial scenario of “leave the car and go to the center by public transport,” and an evening panorama of the Seine or Bois de Boulogne. The most realistic strategy for the first day is not to storm central Paris by car, but to pick up the vehicle, check the insurance, body condition, Crit’Air environmental requirements, and spend the night with easy access to the A10/A11. Parking in the historic center is difficult and expensive, so for an average driver this day works best as an adaptation day: a short urban drive, an early night, and a stress-free start toward the Loire the next day.
