The recommended itinerary splits the drive into two segments: Varenna to Alassio (3 hours) and Alassio to Colmar-sur-Mer (3.5 hours). This avoids the heavy traffic around Marseille and allows for a relaxing beach break. An alternative is to stay overnight in the medieval village of Dolceacqua, 20 km inland from Ventimiglia.

Weather conditions vary dramatically: the Po Valley may be foggy, while the Ligurian coast is typically mild. French Riviera microclimates can bring sudden mistral winds. Check local forecasts for each segment.

From Varenna, the SS36 winds along the eastern shore of Lake Como, with the Grigne mountains rising sharply on the left. The first major natural attraction is the Lario Alps—dramatic limestone peaks visible from the road. Once past Como, the landscape flattens into the Po Valley, but the first stop is the town of Lecco, where you can see the source of the Adda River. The A7 traverses the Apennines through the Genoese hinterland, where chestnut forests and medieval watchtowers punctuate the hillsides.

Descending toward Liguria, the Riviera di Ponente offers terraced vineyards (cinqueterre, though not visible from highway) and olive groves. At Albenga, a detour to the Isola Gallinara provides a stunning marine protected area. The French border at Menton marks entry into the ‚Jardin d’Eden‘—a lush, subtropical paradise with lemon trees and palms lining the road. Colmar-sur-Mer itself is a tiny fishing hamlet with a pebble beach and a 17th-century watchtower.
