Traffic forecaster Bison futé has issued a ‘black’ alert for heavy traffic. Meanwhile, train operator SNCF is bracing for its busiest period of the year. Some 400,000 passengers expected to travel on main lines on Friday, and reservations for the summer are already 10 percent higher than the record-breaking level for the summer of 2019.

This weekend alone, one million travellers are expected to take a train in France, and a third of the 650 TGV Inoui and Ouigo running each day (on 800 mainline trains) are full. 

“We’re doing what we always do, but the trains are fuller and we’re distributing luggage tags to avoid forgotten luggage,” an SNCF Voyageurs spokeswoman told AFP.

The most popular rail destinations this summer are, unsurprisingly, the Mediterranean, the south-west and Brittany, with the “top five” most popular cities being, as last year, Paris, Lyon, Bordeaux, Marseille and Avignon. The east of France is also popular this year, with notable increases in bookings to Nancy (+56 percent over one year), Metz (+50 percent) and Reims (+63 percent).

While travel on French roads is classed as “difficult” or “very difficult” on Friday – orange and red on Bison Futé’s four-colour alert system – Saturday is classed as “extremely difficult” – or black on its colour system, its highest alert level.

Traffic difficulties are expected throughout the weekend, in the south-east and along the Mediterranean Arc as holidaymakers head to popular resorts. Jams are also predicted on the A20, A71 and A75 in central regions; and on the A61, A62 and A63 in the south-west, as well as the A10. 

Meanwhile, the A7 in the Auvergne-Rhône-Alpes, and the A61 and A62 in south-west France will be busy as holidaymakers head back home; and traffic will be difficult on the A8 and A9 freeways, on the coast from the Italian border to the Spanish border.

More specifically, on Friday, Bison Futé urges drivers heading off on holiday to avoid:

• travel in the Île-de-France after 12noon;
• the A1 between Paris and Senlis from 5pm to 7pm;
• the A10 between Orleans and Poitiers from 8am to 8pm, and between Poitiers and Bordeaux from 11am to 5pm;
