In-Depth Cost Analysis & Process

- Price Range: Expect to pay between €100 and €150 for the 60-70 km trip. Factors affecting price:
- Time of day (night/overtime surcharges).
- Number of passengers and pieces of luggage.
- Exact drop-off location in Castelsardo (the historic center is harder to access).
- Journey Time: Approximately 1 hour, depending on traffic on the SS200 and SS134 roads.
When to Choose a Taxi
Consider a taxi if: you are a group of 3-4 people (splitting the cost makes it reasonable); you have a very late-night or early-morning flight when no buses run; you have excessive luggage or mobility issues; or you simply value immediate departure and privacy above cost.
Warning: Unlicensed taxis (“pirate taxis”) may solicit inside the airport. Use only the official taxi rank.
Rental Car: Ultimate Freedom for Exploring
Renting a car at Alghero Airport is arguably the best option for most travelers visiting Northern Sardinia beyond just Castelsardo.
Why Rent a Car for This Route?
- Flexibility: Leave on your own schedule, stop at viewpoints like “Belvedere di Castelsardo” along the way.
- Exploration: Castelsardo is a perfect base for day trips to the Costa Paradiso, Isola Rossa, or the famous La Pelosa beach in Stintino (which requires pre-booked access).
- Convenience: The drive is straightforward: Take the SS291 to Sassari, then the SS200 towards Castelsardo. Use GPS (Google Maps/ Maps.me work well).

| Fuel Cost | Approx. €10-€15 for a one-way trip. |

Enhancing Your Journey
- If Driving: Take the scenic coastal detour via Porto Torres and the SP81 for stunning views before heading inland to Castelsardo.

- First/Last Night Stay: If you have a very early flight, consider spending the last night near Alghero Airport instead of traveling from Castelsardo at dawn.
