Alghero is Sardinia’s most charming coastal town — a Catalan-speaking enclave with medieval walls, a picturesque old town, and access to some of the island’s most dramatic coastline. The town was ruled by Aragon for centuries, and the Catalan influence remains in the architecture, the language, and the seafood. Neptune’s Grotto (Grotta di Nettuno) is 25km away — a stunning sea cave accessible by boat or by 656 steps carved into the cliff. Bosa, with its colourful houses and medieval castle, is 45km south. Alghero Fertilia Airport (AHO) is just 15 minutes from town, making this one of Sardinia’s most convenient entry points.
Why Rent a Car
Northwest Sardinia is perfect for road trips. The coastal road to Bosa (SP49) is one of Italy’s most scenic drives — winding cliffs, hidden coves, and panoramic views. Neptune’s Grotto is easier to reach by car (with a short walk) than by boat. The beaches north of Alghero — Le Bombarde, Lazzaretto, Mugoni — are stunning and only accessible by car. The interior offers nuraghi, wineries, and traditional villages. Public buses exist but are infrequent and don’t reach the best spots. A rental car gives you the freedom to discover hidden coves and hilltop villages that most visitors miss.
What to See
Neptune’s Grotto is the highlight — a massive sea cave with stalactites and stalagmites, accessible by boat from Alghero port or by stairs from Capo Caccia. Bosa is 45km south — pastel-coloured houses, a riverside setting, and a hilltop castle. Le Bombarde and Lazzaretto beaches are 10km north — white sand and turquoise water, perfect for swimming. Capo Caccia (25km west) offers dramatic cliff views and hiking trails. The necropolis of Anghelu Ruju is 8km inland — prehistoric tombs carved into rock. Stintino and the beaches of La Pelosa are 60km north — Sardinia’s most famous white sand beach.
Driving Tips
The SP49 coastal road to Bosa is narrow and winding — take your time and enjoy the views. Speed limits are 50km/h in towns, 90km/h on rural roads. The SS127 and SS131 connect to Sassari and the rest of Sardinia. Parking in Alghero’s old town is limited — use the lots outside the walls and walk in. Neptune’s Grotto parking fills early in summer — arrive before 10am or take the boat. Watch for sheep and goats on rural roads. Italian driving is assertive — stay right, use mirrors, and expect overtaking on narrow roads.
Booking Tips
Alghero Fertilia Airport has good selection and is convenient to town. Book ahead for July and August — northwest Sardinia is popular with Italians. Manual transmission is standard; automatics cost more. Diesel cars are economical for touring. Full insurance is recommended — rural roads can be narrow. If you’re planning to drive to Costa Smeralda (150km), allow 2.5 hours via Sassari. Consider one-way rentals if you’re flying out of Cagliari or Olbia — fees vary by company.
