Quick Answer
The best overall way to travel from Cagliari Airport to Alghero for most travelers is the combined train and bus route. Take a local bus/taxi to Cagliari station, a Trenitalia train to Sassari, and a final ARST bus to Alghero. The total journey takes 3.5 to 4.5 hours and costs approximately â¬20-â¬35. For speed, consider a domestic flight (40 min air time, ~3h door-to-door), and for budget, the direct regional bus services (â¬10-â¬15, ~3h) from nearby Cagliari city are the cheapest.
Option 1: Train + Bus Combo (The Scenic & Flexible Route)
This is the most commonly recommended route for independent travelers, balancing cost, scenery, and flexibility. It involves three distinct legs but utilizes Sardinia's core public transport network.
The 3-Step Journey Explained
- Cagliari Airport to Cagliari Railway Station: Take the CTM public bus Line 1 (â¬1.30, every 20 mins, ~25 min ride) or a taxi (â¬15-â¬25, 15 mins) to the main "Cagliari" railway station (Piazza Matteotti).
- Train from Cagliari to Sassari: This is the main leg. Trenitalia operates Regional (R) and faster InterCity (IC) trains on this line. The journey through Sardinia's interior takes 2.5 to 3 hours.
Train Type Duration Approx. Price (One-Way) Key Features Regionale ~3 hours â¬12 - â¬18 Frequent stops, no reservation needed, basic comfort. InterCity (IC) ~2.5 hours â¬20 - â¬30 Fewer stops, mandatory seat reservation (small fee), more comfortable. Pro Tip: Book IC trains in advance on the Trenitalia website for the best fares. Regional tickets can be bought at the station.
- Bus from Sassari to Alghero: From Sassari's main bus station (adjacent to the train station), take an ARST bus (Line 9323 or similar). Buses run frequently, the ride takes 45-60 minutes, and a ticket costs â¬3-â¬5. Check ARST schedules here.
Deep Dive: Advantages & Challenges
Advantages: Significantly more scenic than the highway; trains offer space to walk and use a toilet; flexible with multiple daily departures; affordable; rail passes are valid.
Challenges: Not a single-ticket solution; requires two changes; luggage must be handled yourself at each transfer; total travel time is highly dependent on connection wait times in Sassari (plan for a 30-60 minute buffer).
Option 2: Domestic Flight (Fastest in the Air, Not Necessarily Door-to-Door)
Flying seems like the obvious quick choice, but the reality requires careful consideration of the total "journey time."
The Flight Route & Airlines
Direct flights between Cagliari Elmas Airport (CAG) and Alghero Fertilia Airport (AHO) are operated by regional airlines. The flight time is a mere 35-45 minutes. However, consider the complete timeline:
- Pre-Flight: Arrive at CAG 1.5-2 hours before departure for check-in and security.
- Flight: 40 minutes.
- Post-Flight: Disembark, collect luggage (15-30 mins), and take a taxi/bus from AHO to Alghero city center (15 mins by taxi).
Total effective door-to-door time: ~3 to 4 hours. Fares vary wildly from â¬40 to over â¬150 one-way based on season and how early you book.
Who Should Fly?
This option is best for: Travelers connecting from a long-haul international flight who value minimizing additional ground travel time; those with limited time in Sardinia who don't mind the cost for perceived speed; business travelers.
Key Consideration: Always compare the total cost and time of flight + airport transfers against the train/bus combo. The time savings are often less dramatic than they appear.
Option 3: Direct & Regional Buses (The Budget Champion)
For the most economical direct service, long-distance buses are the winner. Note that these primarily depart from Cagliari's city center, not the airport itself.
Direct Bus Services
Companies like Deplano and Redentours operate direct coach services between Cagliari (central bus stations like Via Bacaredda) and Alghero. This is a true point-to-point service with no changes.
- Duration: Approximately 3 hours.
- Cost: Typically between â¬10 and â¬15 one-way.
- Frequency: 2-4 departures per day.
- Booking: Essential, especially in summer. Book online via the operator's website or at the bus station.
Comprehensive Analysis
Pros: Extremely cost-effective; direct service; often have luggage compartments; comfortable coaches with air conditioning.
Cons: Requires getting from CAG to the city bus station first (adds â¬1.30 and 30 mins); less frequent than trains; can be subject to road traffic delays; limited schedule on weekends/holidays.
Traveler's Note: The bus takes the scenic coastal and inland roads, offering a different perspective of the island compared to the train.
Option 4: Renting a Car & Driving (Ultimate Freedom)
Driving gives you unparalleled flexibility to explore Sardinia at your own pace and is highly recommended for longer stays.
The Drive: Route & Details
The most efficient route is via the SS131/E25 northwards. It's a well-maintained dual carriageway for most of the way.
- Distance: ~220 km.
- Driving Time: 2.5 to 3 hours non-stop.
- Costs: Rental (â¬30-â¬70/day), Fuel (~â¬30-â¬40), Tolls (minimal on this route).
Major rental companies (Avis, Hertz, Europcar, etc.) have desks at Cagliari Airport. Book months in advance for summer travel.
Strategic Advantages
Beyond just getting to Alghero, a car allows you to: Visit the nuraghe ruins (e.g., Su Nuraxi di Barumini) en route; explore the beautiful Costa Verde or Bosa on the west coast; access remote beaches and countryside agriturismos around Alghero with ease.
Option 5: Taxi & Private Transfer (Door-to-Door Luxury)
This is by far the most expensive option, reserved for specific circumstances.
Cost & Practicalities
A direct taxi from Cagliari Airport to Alghero is not a standard metered fare. It is a pre-negotiated long-distance journey. Expect prices to range from â¬350 to over â¬450 for the one-way trip.
A more structured and often similarly-priced alternative is a pre-booked private transfer. Companies offer fixed rates, professional drivers, and meet-and-greet services.
When Does This Make Sense?
Consider this only if: 1) You are a group of 3-4 people splitting the cost, 2) You arrive on a very late flight with no other options, 3) You have extreme mobility issues or excessive luggage, 4) Money is no object and you value absolute convenience.
For 99% of travelers, this is not a cost-effective choice. Always get a firm quote in writing before agreeing to a long-distance taxi ride.

Traveler Experience & Insider Tips
Beyond schedules and prices, here's practical wisdom for a smoother journey.
Luggage & Connections
- Travel Light: If using the train+bus combo, a backpack or wheeled carry-on is infinitely easier than large suitcases for navigating stations and bus steps.
- Connection Buffer: When booking trains, deliberately choose a connection in Sassari with at least 45-60 minutes between arrival and your bus departure. Delays happen.
- Airport First Stop: Upon landing at CAG, use the free airport Wi-Fi to check real-time status of your chosen transport (train times on Trenitalia app, bus times on ARST site).
Booking & Seasonality
- Summer & Holidays (June-Sept, Easter): Book everythingâtrains, buses, rental carsâweeks or months in advance. Prices soar and availability vanishes.
- Validate Bus Tickets: On local CTM and ARST buses, you must timestamp your ticket in the machine upon boarding. An unvalidated ticket is invalid and can result in a fine.
The Journey Itself
- Sassari Station: The bus station is directly outside the main train station. It's a simple cross-the-plaza transfer.
- Scenic Stretch: The most beautiful part of the train ride is often between Oristano and Macomer. Keep your camera ready.
- Final Approach: The bus ride from Sassari to Alghero winds down from the plateau to the coastâa lovely introduction to the area.

Renting a car can be an excellent option for this journey, especially if you plan to explore Sardinia's scenic interior or west coast.

Your only reliable options are: 1) A pre-booked private transfer (the most convenient but expensive choice), 2) A taxi for an extremely high fare (â¬350+), or 3) Staying overnight in Cagliari and continuing your journey the next morning. Always check the latest schedules for your arrival date.
Is the train from Cagliari to Sassari scenic?
Yes, the Trenitalia regional train journey from Cagliari to Sassari offers beautiful views of Sardinia's rugged interior, passing through the historic region of Logudoro and near Monte Acuto.
