Liège to Sète Road Trip: Ultimate Guide to French Motorway Gems

The A75 motorway, known as La Méridienne, terminates near Sète after descending from the Massif Central. This road trip connects the Meuse River in Liège to the Mediterranean lagoons of Sète, crossing three countries and four French regions. Expect 8–9 hours of driving not counting stops, covering about 800 km (500 miles).

A quirky fact: the A75 features the Millau Viaduct, the tallest bridge in the world with a mast summit at 343 meters, towering above the Tarn Valley. The entire route from Liège to Sète passes through 12 toll plazas and offers a mix of flat plains, volcanic ranges, and coastal plains.
