Sardinia is the second-largest island in the Mediterranean after Sicily, an autonomous Italian region of rocky coasts, mountains and Bronze Age stone towers. It lies about 200 kilometres west of the Italian mainland and just south of Corsica, with roughly 1,850 kilometres of coastline and around 1.5 million inhabitants.
Most visitors come for the sea: sandy coves and clear water in the north-east around Olbia and the Costa Smeralda, the walled old town of Alghero in the north-west, where a dialect of Catalan is still spoken, and long city beaches near Cagliari, the capital, in the south. Inland the island is quieter, dotted with thousands of nuraghi, the stone towers of the Nuragic civilization. Distances are bigger than the map suggests, so many travellers choose one coast as a base. Holiday apartments, villas and country houses suit families, groups and longer stays.
The north-east is one of the most visited parts of the island. Olbia, a working port city with its airport on the edge of town, is a practical base with shops, restaurants and beaches within a short drive. To the north, the Costa Smeralda around Porto Cervo and Baja Sardinia is a planned resort coast of villas and marinas, developed from 1961, which is busy in July and August and calm outside them. Palau and the town of La Maddalena suit travellers who want boat days among the islands of the national park.
In the north-west, Alghero combines an old town inside sea walls and towers with the cliffs of Capo Caccia and the bay of Porto Conte nearby, and it has its own airport, which helps if you prefer not to drive. Cagliari, in the south, is a real city with museums, markets and Poetto beach, a good choice in spring and autumn. Town apartments, coastal villas with pools and farm stays inland are all common.
Sardinia's shore changes from region to region. The north-east has pale sand between granite boulders, and the Arcipelago di La Maddalena National Park, established in 1994, protects the islands of La Maddalena, Caprera, Spargi, Budelli, Razzoli and Santa Maria together with the sea around them. Near Alghero, Neptune's Grotto opens just above the waterline at the foot of the Capo Caccia cliffs; it is reached by a stairway of 654 steps cut into the rock in 1954 or by boat from Alghero, and only when the sea is calm.
The limestone coast around Cala Gonone on the east side is known for sea caves and diving. In Cagliari, Poetto runs for about 8 kilometres from the Sella del Diavolo headland towards Quartu Sant'Elena, backed by lagoons where greater flamingos feed. A regional landscape plan limits new building along the coast outside existing towns.
From about the 18th century BC the Nuragic civilization built round stone towers called nuraghi, and some 7,000 of them still stand across the landscape. The best known, Su Nuraxi at Barumini, has a central tower built between the 17th and 13th centuries BC, later ringed by four corner towers, with a village around it that was lived in from the 13th to the 6th century BC. It was added to the UNESCO World Heritage List in 1997.
Phoenician traders came next, followed by Carthage in the late 6th century BC and Rome from 238 BC. In the Middle Ages the island was divided into four self-governing kingdoms known as judicates. The Crown of Aragon took control in 1324, and in 1720 the island passed to the House of Savoy, whose Kingdom of Sardinia became the Kingdom of Italy in 1861. Sardinian and the Algherese form of Catalan are recognised minority languages.
Traditional Sardinian cooking leans on the land more than the sea: meat, cheese, grains and vegetables, with seafood a smaller part of the picture. Porcheddu, suckling pig roasted on a spit, is the classic feast dish, and pecorino sardo is the everyday sheep's cheese. Pane carasau, a paper-thin crisp flatbread that keeps for a long time, was once food for shepherds and is now served everywhere. On the coast you will find bottarga, cured fish roe, along with squid and tuna.
The island's best-known wines are the red Cannonau and the white Vermentino, and mirto, a liqueur made from myrtle, is a common way to end a meal. Parts of the interior are also known for an unusually high share of people who live past 100, which has made the island a subject of study for researchers of longevity.
Sardinia has three main international airports: Olbia Costa Smeralda (OLB) in the north-east, renamed in 2025 after Prince Karim Aga Khan IV; Alghero-Fertilia (AHO), about 8 kilometres north-west of Alghero; and Cagliari Elmas (CAG) in the south. Ferries link Olbia, Golfo Aranci, Porto Torres, Arbatax and Cagliari with mainland ports such as Genoa, Livorno, Civitavecchia and Naples, and with France and Barcelona.
The island has no motorways, but toll-free dual carriageways connect the main towns, airports and ports; the SS131 Carlo Felice runs from Cagliari to Porto Torres in the north. Regional ARST buses reach every town at least once a day, yet small villages and many beaches are practical only by car. Roads in the interior are winding, so allow extra time and plan long transfers for daylight.
Sardinia has a Mediterranean climate. On the coasts, January temperatures typically range from about 9 to 16°C and July from about 23 to 31°C, while the mountains are much cooler and the Gennargentu range, which rises to 1,834 metres at Punta La Marmora, can see snow and has small ski areas. The coast around Cagliari is the driest part of the island. The mistral, a north-westerly wind, blows on and off through the year, most often in winter and spring, and it can make some beaches rough while others stay sheltered.
July and August are the hottest and busiest months, especially on the Costa Smeralda and around La Maddalena. Late May, June and September usually bring warm sea and fewer crowds, and October can still be pleasant. Winter suits city stays in Cagliari and walking inland rather than beach holidays.
June and September offer warm sea, long days and fewer crowds than July and August, when the north-east coast is at its busiest. May and early October suit walking and sightseeing. Winter is mild on the coast but quiet, and many seaside businesses close.
Choose by the trip you want. Olbia, the Costa Smeralda and La Maddalena suit beach and boat holidays in the north-east. Alghero suits couples and travellers without a car. Cagliari suits city breaks with beaches nearby, and inland villages suit those looking for quiet and local life.
Fly into Olbia (OLB) for the Costa Smeralda, Porto Cervo and La Maddalena, Alghero (AHO) for the north-west and Capo Caccia, and Cagliari (CAG) for the south, Poetto and Barumini. Because the island is large, landing close to your base saves hours of driving.
For most trips, yes. Regional buses connect the towns, but many beaches, nuraghi and inland villages are hard to reach without a car. If you base yourself in Alghero or Cagliari and stay mostly in town, you can manage with buses, taxis and boat trips.
A week is enough to enjoy one region well, for example the north-east coast with a day among the La Maddalena islands. With ten days to two weeks you can combine two areas, such as Alghero and Cagliari, and add Barumini or the east coast on the way.
Nuraghi are round dry-stone towers built by the Nuragic civilization from about the 18th century BC. Around 7,000 survive. The complex of Su Nuraxi at Barumini, with its central tower, bastion and surrounding village, is on the UNESCO World Heritage List.
Yes. Holiday rentals in Italy must have a national identification code, the CIN, issued through the Ministry of Tourism's accommodation database. The code has to appear in every online listing and be displayed outside the building, so you can check it before booking.
Yes. Many north-eastern beaches have shallow water in sheltered coves, Poetto in Cagliari is a long, easy city beach, and boat trips and nuraghi give children plenty to explore. A villa or apartment with outdoor space makes the hot summer afternoons easier.
