Cagliari to Positano: Ultimate Road Trip Guide

The road from Cagliari to Positano is not a continuous line on a map: it demands a ferry crossing at the Strait of Bonifacio. The route involves the SS131 Carlo Felice from Cagliari to Porto Torres, a ferry to Genoa or Civitavecchia, then a coastal drive down the A1/E45 and SS163 Amalfi Drive to Positano. The total driving distance is roughly 1000 km of Sardinian highways plus 250 km on the mainland, excluding sea legs. Ferries from Sardinia to the mainland run regularly; a typical crossing takes 6–8 hours to Genoa or 4–5 hours to Civitavecchia. This journey blends two distinct worlds: the stark, ancient landscapes of Sardinia and the dramatic, terraced cliffs of the Amalfi Coast. Knowing is it worth driving Cagliari to Positano depends on your appetite for logistical planning and reward of stunning contrasts.

How long to drive Cagliari to Positano purely on wheels is about 8–9 hours excluding ferry. Including ferry and waiting, budget at least 15 hours total travel time. The best route uses the SS131 Carlo Felice, a divided highway that cuts through the mountainous heart of Sardinia. At Porto Torres, you board the ferry. On the mainland, from Genoa take the A7/A1 south to Naples, then the Autostrada A3 to Salerno, finally the SS163 Amalfitana coastal road to Positano. Fuel stations in Sardinia are adequately spaced, but fill up before long stretches; the SS131 has service areas every 30–40 km. The Amalfi Drive has limited stations; fill in Salerno. The ferry cost varies by season; booking ahead is wise. For a deeper look at optimizing stops, see how to find the best stops and hidden gems between cities.

On the Amalfi Coast, the Valley of the Mills in Amalfi offers easy walks. Pet-friendly stops: On the SS131, the area of Oristano has a fenced rest area (Sosta Pet). In Positano, Hotel Palazzo Murat welcomes pets. Infrastructure safety: Sardinian highways are well-lit only in urban sections. The Amalfi Drive has many tunnels with poor lighting; use headlights always. Fatigue management: Take a break at the Autogrill Lazio Est on the A1 (piazza di servizio) with dedicated rest rooms. For a quick nap, the Porto Torres ferry terminal has waiting rooms.

• Safety tips: Watch for sheep on Sardinian roads; on the Amalfi Drive, park in designated areas only (fines are steep).

• Family stop: The Sardinia Miniature Park in Mandas (SS128) features scale models of nuraghe.

Sardinia's interior is a patchwork of granite mountains, cork oak forests, and Bronze Age nuraghe towers. The SS131 passes near the Giara di Gesturi, a basaltic plateau with wild horses. As you approach the northern coast, the scenery softens into Mediterranean macchia and white sand beaches like La Pelosa. The ferry crossing offers views of Corsica on clear days. On the mainland, the drive down the A1 is monotonous until you reach the Campanian coast. The SS163 Amalfi Drive clings to vertical cliffs, offering panoramic views of turquoise coves, lemon groves, and pastel-colored villages. Things to do between Cagliari and Positano include detours to Matera (UNESCO), the ancient city of Pompeii (UNESCO), and the Roman ruins of Nora in Sardinia. Local commerce: in Sardinia, buy pecorino cheese, cannonau wine, and filigree jewelry. In Campania, limoncello, hand-painted ceramics, and mozzarella di bufala are iconic.
