Quick Answer
The best overall way to get from Cagliari Airport to the University of Cagliari is by the direct public bus ARST line 731. It's cheap (€1.30-€3.00), frequent (every 20-30 mins), and takes only 15-20 minutes to reach stops near the campus. For maximum convenience or late-night arrivals, a taxi (€25-€40, 10-15 mins) is the recommended alternative. There is no direct train service.
Public Bus (ARST Line 731) – The Best & Cheapest Option
The ARST (Azienda Regionale Sarda Trasporti) bus line 731 is the primary and most efficient public transport link between Cagliari Elmas Airport (CAG) and the city center, with stops conveniently serving the University of Cagliari.

Step-by-Step Guide & Deep Analysis
1. Finding the Bus Stop: Upon exiting the arrivals hall at Cagliari Airport, turn left. The ARST bus stop is clearly signed and located just a few meters away, opposite the taxi rank.
2. Choosing the Right Ticket: For a direct journey to the university, the €1.30 urban ticket is sufficient. The €3.00 "airport ticket" is only necessary if you plan a longer, multi-leg journey beyond the standard 90-minute validity. Validate your ticket in the machine upon first boarding.
3. During the Ride & Alighting: Inform the driver of your stop (e.g., "Viale Merello, per l'università") and keep an eye on Google Maps. The stops are announced but not always clearly in English.
Pros: Extremely cost-effective, direct, frequent, good luggage space, eco-friendly.
Cons: Can be crowded during peak student hours, subject to city traffic delays.

Taxi & Private Transfer – Fast & Door-to-Door Convenience
For those prioritizing speed, convenience, or traveling in a group, taxis and pre-booked private transfers are the premium choice.
| Option | Price (Approx.) | Time | Booking |
|---|---|---|---|
| Official Airport Taxi | €25 - €40 (metered) | 10-15 mins | Rank outside arrivals |
| Pre-booked Private Car | €30 - €50 (fixed price) | 10-15 mins | Online in advance |
| Larger Van (6-8 pax) | €50 - €80 | 10-15 mins | Online in advance |
In-Depth Comparison & When to Choose
Airport Taxi (Freccia Blu / Radio Taxi):
- Always available at the rank. Ensure the meter is running.
- Fare includes supplements for airport service, luggage, and night rides.
- Ask for a receipt (ricevuta).
Pre-booked Private Transfer:
- Advantages: Fixed price (no surprise costs), driver meets you with a name sign, often more comfortable vehicles, can be booked for any hour.
- Ideal for: Late-night/early-morning flights, large groups, travelers with lots of luggage or mobility issues, stress-averse visitors.
- Use reputable platforms like Welcome Pickups, SunTransfers, or local operators.
Cost Justification: While expensive for a solo traveler, for a group of 3-4, the per-person cost rivals that of the bus while offering unparalleled convenience. It is the only recommended option for arrivals after midnight when the bus has stopped.
Train – Why It's Not Recommended
Despite Cagliari having a regional train network, it is not a practical option for travel from the airport to the university. Here’s a detailed breakdown of the complications:
The Two-Station Problem & Complicated Transfer
- Airport to Elmas Station: Cagliari Airport is not connected to a train station. The nearest station, "Cagliari Elmas," is 2.5 km away. You would need to take a local bus (e.g., line P) or a taxi (€8-€12) just to reach the train.
- Elmas to Cagliari Station: From Elmas, trains run to the main "Cagliari" station. This journey takes about 7-10 minutes, with tickets costing around €1.30.
- Cagliari Station to University: The main station is still 2-3 km from most university buildings. You would then need to take a third vehicle – a city bus (e.g., line 5 or 11) or another taxi – to reach your final destination.
Total Estimated Journey: 60-90 minutes, €8-€15+, with 2-3 separate vehicle changes. This compares unfavorably to the direct 20-minute bus (731) or 15-minute taxi.
Conclusion: The train network is useful for exploring Sardinia (e.g., to Iglesias or the beach at Poetto) but is highly inefficient for airport-to-university transfer. It should only be considered in extraordinary circumstances where all other options are unavailable.

Traveler Experience & Practical Tips
Insights beyond the schedules and prices to ensure a smooth journey.
Navigating the University Campus
The "University of Cagliari" is spread across multiple faculties in different city areas. The main clusters are:
- Science, Engineering, Architecture: Near the "Viale Merello" bus stop (served by line 731).
- Humanities, Law, Economics, Rectorate: Around "Piazza d'Armi" and "Via Università." Get off at "Piazza Giovanni XXIII" (731) and walk.
- Medicine & Biology: Located at the Monserrato campus, further out. From the airport, take bus 731 to "Piazza Matteotti" and transfer to a dedicated shuttle or bus (e.g., line 5).
Always confirm the exact address of your department.
Essential Tips for a Smooth Trip
- Have Cash (Euros): While bus ticket machines accept cards, smaller tabacchi shops or taxi drivers may prefer cash, especially for small amounts.
- Sunday & Holiday Schedules: Bus frequency on line 731 is significantly reduced. Check the ARST website for "festivi" timetables.
- Use Real-Time Apps: The "Moovit" or "Google Maps" apps provide live tracking for ARST buses, crucial for timing your arrival at the stop.
- Peak Traffic: Morning (8-9 AM) and late afternoon (5-7 PM) traffic can add 5-10 minutes to both bus and taxi journeys.
- Student Card Discounts: Regular students residing in Sardinia may be eligible for subsidized monthly passes, but these are not relevant for one-time airport transfers.
FAQs: Cagliari Airport to University of Cagliari
Is there a direct bus from Cagliari Airport to University of Cagliari?
Yes, the ARST line 731 provides a direct and frequent connection between Cagliari Elmas Airport (CAG) and several key stops near the University of Cagliari campus, such as Viale Merello and Piazza Giovanni XXIII. The journey takes about 15-20 minutes.
How much is a taxi from Cagliari Airport to the University?
A taxi from Cagliari Airport to the University of Cagliari typically costs between €25 and €40, depending on traffic and exact destination. The ride takes 10-15 minutes. It is a fixed-rate metered fare from the airport.
Can I take a train from the airport to the University?
No, it is not practical. The airport lacks a train station. The closest station (Elmas) is 2.5 km away, requiring a taxi/bus transfer. From there, you'd take a train to Cagliari's main station and then another bus to the university, making it a long (60-90 min) and costly multi-leg journey. The direct bus is vastly superior.
What is the cheapest way to get to the University of Cagliari from the airport?
The public bus (ARST line 731) is by far the cheapest option, costing only €1.30 for a standard 90-minute ticket. It offers direct service and excellent value.
How do I handle large luggage on the airport bus?
The ARST 731 buses have dedicated luggage racks inside. Standard suitcases and backpacks fit easily. While space is good, during peak times it can get crowded, so keep your luggage close.
I am arriving late at night. What are my options?
After the last ARST 731 bus (around midnight), your only options are a taxi from the 24/7 rank outside arrivals or a pre-booked private transfer. Booking a private car in advance is recommended for guaranteed service and fixed rates for late-night arrivals.
Is the University of Cagliari walkable from the airport?
No. It is approximately 9-10 km away via unsafe, non-pedestrian-friendly roads. Walking is strongly discouraged. Use the bus or a taxi.
What is the best option for a group of 4 people?
For a group of 4, a taxi or pre-booked private van is often the best choice. Splitting a €30-€40 fare makes it €7.5-€10 per person – comparable to the bus but with door-to-door convenience and no wait.
