Planning your first week in Sardinia? One of the first decisions is whether to fly into Olbia in the northeast or Cagliari in the south. Both are excellent gateways, but they lead to different kinds of holidays. The best airport is not necessarily the one with the cheapest flight: it is the one closest to the places you actually want to visit.
The quick answer: choose Olbia if your seven days are focused on the Costa Smeralda, La Maddalena and northeastern beaches. Choose Cagliari if you want a mix of historic streets, restaurants, archaeology and southern beaches. Neither airport is universally better, and either can work for a first visit.
Olbia or Cagliari: what is the real difference?
Olbia is the natural entry point for much of northeastern Sardinia. Its location makes it convenient for the Costa Smeralda, the Gallura region, San Teodoro and trips towards Palau and the La Maddalena archipelago. Olbia itself is a functioning town with restaurants and a waterfront, but many travellers use it as a base or starting point for a beach-oriented itinerary.
Cagliari is Sardinia's regional capital and offers a different experience. You can explore historic districts, visit museums and archaeological sites, enjoy a lively dining scene and reach the long urban beach at Poetto. From the city, southern coastal areas such as Villasimius, Pula and Chia become possible excursions, though journey times vary by route and season.
Choose Olbia for beaches and the northeast
For travellers dreaming of clear turquoise water, granite scenery and island boat trips, Olbia is a compelling choice. The northeastern coast includes the famous Costa Smeralda, the beaches around San Teodoro and access towards Palau, where ferries depart for La Maddalena. This area is especially appealing if you plan to rent a car and spend most days exploring different stretches of coastline.
However, famous does not automatically mean quiet or inexpensive. In peak summer, popular beaches and resort towns can be crowded, parking may be limited and accommodation costs can rise. Check any beach-access or reservation rules for your intended dates.
Choose Cagliari for culture, food and southern beaches
Cagliari works particularly well if you want variety without changing hotels constantly. Its Castello district, Roman amphitheatre, archaeological museum and neighbourhood restaurants give you plenty to do away from the sand. Poetto beach is within the urban area and can be reached by local public transport, making the city especially attractive for visitors who do not want to drive every day.
For beach excursions, the south offers very different landscapes: the coastline around Villasimius to the east, and the beaches of Pula and Chia to the southwest. Some destinations are straightforward by car, while others require advance planning, seasonal services or a longer drive than they appear to on a map.
Which airport is better if you do not rent a car?
Cagliari is often the easier choice for a city-based, car-free week. The airport has a nearby railway station with connections to the city, and Cagliari has an established urban bus network. You can combine sightseeing, dining and visits to Poetto without needing a vehicle every day.
Olbia also has public transport and airport connections, but visiting a succession of remote northeastern beaches can be more complicated without a car. Regional buses and seasonal services may help, yet frequencies and return times need checking. If you are travelling without driving, choose accommodation based on the actual transport links, not just the distance shown on a map.
Is Olbia better for La Maddalena?
Yes, if La Maddalena is one of the main reasons for your trip, Olbia is generally the more logical airport. From the northeast, you can travel towards Palau and take the ferry to La Maddalena. The archipelago is celebrated for its island landscapes, but boat trips, parking, ferry schedules and protected-area rules should be checked for your travel dates.
Trying to include La Maddalena as a casual day trip from Cagliari would create a long, tiring journey and is usually not an efficient use of a seven-day holiday.
Is Cagliari better for Chia, Nora and Villasimius?
For a southern itinerary, yes. Cagliari is well positioned for exploring the archaeological site of Nora near Pula, the coastal scenery around Chia and the beaches of Villasimius. These are different directions from the city, so it makes sense to dedicate separate days rather than trying to see them all at once.
Visitors interested in Sardinian history may especially appreciate combining Cagliari's museums with Nora's ancient remains. Travellers focused on swimming can instead spend more time along the southern coast.
Which airport is cheaper?
There is no permanent answer. Airfares change with the departure city, airline, season, booking date and luggage allowance. Accommodation and rental-car prices also vary between destinations. A cheaper flight to the opposite end of the island can become a false economy once you include fuel, transfers, extra driving and lost holiday time.
Compare the total trip cost: flight, airport transfer, accommodation, car rental if needed and the distance to your main activities. For a seven-day trip, convenience is often worth more than a small difference in airfare.
What about Alghero airport?
There is a third major airport worth considering: Alghero Fertilia in northwestern Sardinia. If your wish list includes Alghero's historic centre, the Riviera del Corallo, Bosa or northwestern coastal scenery, Alghero may be more convenient than either Olbia or Cagliari. It is worth checking all three airports before booking, especially if you have flexible flight options.
A seven-day itinerary from Olbia
For a relaxed first visit, consider staying in one or two places in the northeast rather than moving every night.
- Day 1: Arrive in Olbia, settle in and explore the town.
- Day 2: Enjoy a beach day around San Teodoro or another accessible coastal area.
- Day 3: Explore part of the Costa Smeralda, allowing time for viewpoints and village stops.
- Day 4: Travel towards Palau and visit La Maddalena, subject to ferry schedules.
- Day 5: Take a boat excursion or enjoy another northeastern beach.
- Day 6: Discover inland Gallura, local food or a quieter coastal destination.
- Day 7: Return to Olbia with enough time for your flight.
This is a flexible outline, not a promise that every excursion will operate on every date. Boat trips and seasonal activities depend on weather and availability.
A seven-day itinerary from Cagliari
If you prefer to combine city life with southern beaches, a Cagliari-based week can be rewarding without requiring constant hotel changes.
- Day 1: Arrive in Cagliari and explore the Marina district.
- Day 2: Discover Castello, museums and historic viewpoints.
- Day 3: Relax at Poetto and enjoy the city's food scene.
- Day 4: Visit Pula and the archaeological site of Nora.
- Day 5: Explore Chia and the southwest coast.
- Day 6: Spend a day around Villasimius or choose a slower city day.
- Day 7: Enjoy a final breakfast and depart from Cagliari.
For travellers without a car, replace harder-to-reach coastal days with guided excursions or destinations served by confirmed public transport.
Should you fly into one airport and out of the other?
An open-jaw itinerary—arriving in Olbia and departing from Cagliari, or vice versa—can make sense if you want a longer road trip through multiple regions. But for a first seven-day visit, the transfer between north and south can consume valuable holiday time. It also may involve one-way rental-car fees and different flight prices.
If your priority is a relaxed beach holiday, flying in and out of the same airport and concentrating on one region is often the better plan.
What changes by season?
In July and August, beach resorts can be busy, accommodation should be booked early and popular coastal roads may be congested. Spring and autumn can be excellent for sightseeing, walking and exploring towns, although swimming conditions, beach services and boat excursions vary with weather and season. Winter visitors may find Cagliari's year-round urban attractions particularly appealing, while some summer-oriented businesses elsewhere operate reduced schedules.
The verdict: Olbia or Cagliari for seven days?
Fly into Olbia if your dream holiday is mainly northeastern beaches, Costa Smeralda and La Maddalena. Fly into Cagliari if you want historic neighbourhoods, food, archaeology and a combination of city life and southern beaches. If you are travelling without a car, Cagliari may be the more convenient starting point for a varied week.
Whichever airport you choose, resist the temptation to cross the entire island in seven days. Sardinia rewards slower travel: fewer long transfers, more time in the places you came to see.
