Siena to Durbuy: A Road Trip Through Europe's Heartland

The rest area at Aire de l'Ain (A40, France) offers a panoramic restaurant overlooking the Jura. For families, the Zoo de la Flèche near Le Mans is a worthwhile detour, but closer to the route, Parc de l'Ourthe in Durbuy has a playground and animal farm.

South of Siena, the Crete Senesi lunar-like clay hills give way to the Chianti vineyards. Near Florence, the A1 skirts the Apennines before plunging into the Po Valley at Bologna. The Alps begin after Milan; the A4 climbs through the Aosta Valley, where Mont Blanc (4,808 m) dominates the horizon. At the Mont Blanc Tunnel (11.6 km), you cross into France at 1,381 m elevation.

Descending into the Chamonix valley, the scenery shifts to glacial valleys and Alpine meadows. As you follow the A40 south of Geneva, the Jura Mountains unfold—rolling limestone hills covered in dense forests. The A5 enters the Ardennes near Sedan, with the Meuse River valley opening into the deep green hills of southern Belgium. Durbuy itself sits in the Ourthe River gorge, a fairytale of cobblestones and slate roofs.
