Carloforte and its Tabarkin heritage

Carloforte is the only town on San Pietro, a small island off Sardinia’s south-west coast, and it doesn’t feel like anywhere else on the island — pastel-fronted houses along a harbour that could pass for Liguria, a dialect that isn’t Sardinian, and a food culture built around tuna and couscous rather than the pecorino and porceddu of the mainland. The reason goes back to 1738, when the King of Sardinia resettled Ligurian families here after two centuries of exile on Tabarka, an island off the Tunisian coast.

From Tabarka to San Pietro, in one resettlement

Carloforte’s founding families were originally from Pegli, near Genoa, coral fishermen who settled the island of Tabarka off the Tunisian coast in the 16th century at the invitation of a Genoese noble family. They lived there for roughly two centuries, developing their own dialect and customs while remaining culturally Ligurian, before Barbary corsair raids and instability made the position increasingly precarious. In 1738, the King of Sardinia offered the community this then-uninhabited island in exchange for resettlement, and around 400 families made the move — the origin of both the town’s name, Carlo Felice’s forte, and its enduring Ligurian identity.

Tabarchino, still spoken

The dialect these settlers brought with them, Tabarchino, is a form of Ligurian rather than Sardinian or Italian, and it’s still spoken by a meaningful part of Carloforte’s population today — street signs and shopfronts around town often carry it alongside Italian, a smaller-scale echo of the bilingual signage found in Alghero’s Catalan quarter. For the wider picture of how Sardinia’s several minority languages compare, see the Sardinian language and identity.

What makes Tabarchino particularly striking as a linguistic case is how completely isolated its development has been — nearly three centuries on a small Sardinian island, surrounded by Sardinian and Italian speakers, and the dialect has still kept close enough to its Ligurian roots that speakers from Liguria itself can generally follow it. Local cultural associations run periodic efforts to keep the language active among younger residents, including in some school settings, given the same generational decline affecting minority languages across the island more broadly.

Walking the town itself

Carloforte’s centre runs along a curved harbourfront lined with pastel-painted buildings, most three or four storeys, that give it a distinctly Ligurian silhouette against the otherwise Sardinian coastline around it. Corso Cavour and the streets running back from the water form the town’s main shopping and dining stretch, narrow enough in places to feel closer to a Genoese vicolo than a typical Sardinian piazza. Piazza Carlo Emanuele III, named for the king who resettled the community here, sits at the heart of the old town and is worth a slow pass in the early evening, when the aperitivo crowd fills its cafés and the harbour light softens.

The tonnara and Carloforte’s tuna tradition

Tuna fishing shaped Carloforte’s economy for centuries, centred on the tonnara, the fixed trap-net system used to catch bluefin tuna as they migrated past the island each spring. The technique itself is Sicilian in origin but was well established across the Mediterranean by the time Carloforte’s founders arrived, and the tonnara here operated as one of the last active traditional tuna traps in Italian waters before commercial fishing methods and stricter tuna quotas changed the economics of running it.

The mattanza, the traditional and now largely retired method of harvesting the trapped tuna, has faded from active practice, but the tonnara’s history and its place in the island’s food culture are still very much alive — a guided visit covers both.

Tuna still dominates the town’s restaurant menus, prepared in ways found nowhere else on the island — tonno alla carlofortina, cooked with tomatoes, olives and capers, is the dish to order.

Couscous, the town’s most surprising dish

Carloforte’s most distinctive food isn’t tuna but couscous alla tabarchina — a legacy of the community’s time in North Africa, served with a fish or vegetable broth rather than the meat-based versions found across the Maghreb. It’s a genuinely unusual thing to find on a Sardinian menu, and most of the town’s restaurants along the harbourfront serve their own version. See what to eat in Sardinia for how it sits alongside the island’s more typical dishes.

Beyond couscous and tuna, Carloforte’s kitchens carry other small Ligurian echoes rarely found elsewhere on the island — pesto and focaccia both turn up on menus in forms closer to their Genoese originals than to anything typically Sardinian, a direct thread back to the founding families’ origins near Genoa centuries before Tabarka or San Pietro entered the story. It’s worth ordering at least one clearly Ligurian dish alongside the more famous tuna and couscous, if only to taste how distinct this town’s food culture really is from the rest of the island.

Getting there and around San Pietro

Ferries run to Carloforte from both Calasetta, on neighbouring Sant’Antioco, and from Portovesme on the mainland, with the Calasetta crossing shorter at around 25 minutes. Both routes run frequently through the day in peak summer, thinning out to a more limited timetable in winter, and it’s worth checking the return schedule before setting off rather than assuming a boat back will always be waiting — missing the last crossing means an unplanned night on the island. A sailing tour linking Carloforte with Calasetta and Sant’Antioco is a relaxed way to see all three in a single day without needing to plan separate ferry crossings.

The rest of San Pietro island

Beyond Carloforte’s harbour, San Pietro island itself is worth exploring for at least half a day if time allows — a small, largely uninhabited landscape of low hills, coastal cliffs and beaches accessible by scooter or car from the town centre. La Punta delle Colonne, at the island’s south-western tip, has two Roman-era stone columns marking what was once a temple site, framed against dramatic cliffs and open sea in one direction. The island’s beaches, smaller and less developed than those found on the Sardinian mainland nearby, tend to stay considerably quieter even in August, largely because the ferry crossing filters out the more casual day-tripper traffic.

Sant’Antioco, the bigger island next door

Sant’Antioco, connected to the Sardinian mainland by a causeway rather than needing a ferry, makes a natural pairing with a Carloforte day trip — its own town carries a different history again, Phoenician and Punic rather than Ligurian, with a tophet sanctuary and catacombs that trace the island’s occupation back well over two thousand years before the Tabarchino settlers ever arrived.

The contrast between the two islands’ histories, ancient Phoenician on one and 18th-century Ligurian on the other, is part of what makes combining them in a single trip worthwhile rather than repetitive. Between the two islands and Iglesias on the mainland nearby, this south-west corner of Sardinia rewards a full day rather than a rushed half-day detour from Cagliari.

Carloforte compared with its island neighbours

The south-west corner of Sardinia has three distinct island communities within a short crossing of each other, each with its own separate history.

	Carloforte (San Pietro)	Sant’Antioco	Calasetta
Origin	Ligurian resettlement, 1738	Phoenician-Punic, ancient	Ligurian resettlement, 1770
Connection to mainland	Ferry only	Causeway	Causeway
Language heritage	Tabarchino (Ligurian)	Standard Sardinian/Italian	Also Tabarchino
Defining trait	Tuna, couscous, harbour town	Ancient ruins, Punic tophet	Beaches, smaller sibling to Carloforte

Calasetta, on Sant’Antioco’s western tip, shares Carloforte’s Ligurian Tabarchino heritage — it was settled a few decades later by families from the same Tabarka community — but it’s reachable by road via the Sant’Antioco causeway rather than needing its own ferry, which makes it a useful base for anyone who wants the Tabarchino cultural connection without committing to an island crossing.

Carloforte’s tuna festival

Late May brings the Girotonno, Carloforte’s tuna festival, when the town’s kitchens and a run of visiting chefs from around the Mediterranean turn tuna into the centre of several days of cooking demonstrations, tastings and competitions. It’s a genuinely good reason to time a visit specifically around the date, both for the food itself and for a livelier, more festival-driven atmosphere than the town’s usual quiet pace — accommodation books up accordingly, so planning ahead matters more than for an ordinary summer visit.

Where this fits in a wider trip

Carloforte works well as a day trip from Cagliari, roughly 90 minutes to Portovesme plus the ferry crossing, or as an overnight stop for a more relaxed pace — see day trips from Cagliari for how it compares against the region’s other options. Anyone building a longer south-west itinerary should weigh an overnight stay seriously: the harbourfront’s evening atmosphere, with the aperitivo crowd out and the fishing boats settled for the night, is a genuinely different experience from the quicker, more transactional feel of a same-day round trip. Driving in Sardinia covers the roads out to the south-west coast, which run quieter than the routes toward the more visited north.

Coral, the trade that started it all

It’s worth remembering, walking Carloforte’s harbourfront today, that coral rather than tuna was the original reason this community existed at all — the founding families were coral fishermen first, drawn to Tabarka in the 16th century specifically for the reefs off the Tunisian coast, and it was only after resettlement on San Pietro that tuna became the town’s defining trade.

Coral fishing itself has largely died out here as a commercial activity, undermined by decades of overfishing across the Mediterranean and, more recently, by conservation restrictions on harvesting it at all, but the craft tradition it left behind hasn’t disappeared entirely. A handful of jewellers and artisan shops around Corso Cavour and the streets just back from the harbour still work coral into rings, necklaces and earrings, some using old Ligurian techniques brought over with the original settlers, worth a browse for anyone interested in the fuller arc of the town’s Genoese-Tabarkin story rather than just its food.

Frequently asked questions about visiting Carloforte

How do I get to Carloforte?

By ferry, either from Calasetta on Sant’Antioco (around 25 minutes) or from Portovesme on the Sardinian mainland (35-40 minutes); both routes carry cars as well as foot passengers.

Is Tabarchino still spoken in Carloforte today?

Yes, by a meaningful part of the population, particularly older residents, alongside standard Italian.

What food is Carloforte known for?

Tuna, prepared in dishes like tonno alla carlofortina, and couscous alla tabarchina — a legacy of the community’s time in Tunisia before resettlement in 1738.

Is Carloforte worth visiting as a day trip from Cagliari?

Yes, though it makes for a fairly full day given the drive and ferry crossing; an overnight allows a more relaxed pace and time to properly enjoy the harbourfront in the evening.

What is the tonnara in Carloforte?

The traditional fixed trap-net system historically used to catch migrating bluefin tuna; a guided visit covers its history and its role in the town’s economy.

Can I bring a car to San Pietro island?

Yes — both ferry routes to Carloforte carry vehicles, though the town itself is compact enough to explore easily on foot.

Is Carloforte connected to Sant’Antioco by bridge?

No — Sant’Antioco is connected to mainland Sardinia by a causeway, but reaching Carloforte on San Pietro still requires a separate ferry crossing.

What is the Girotonno tuna festival?

Carloforte’s late-May tuna festival, drawing chefs from around the Mediterranean for several days of cooking demonstrations, tastings and competitions built around the town’s tuna tradition; it’s worth booking accommodation well ahead if planning a visit around it.

Is Calasetta the same as Carloforte?

No — Calasetta sits on neighbouring Sant’Antioco, reachable by road via a causeway, and shares Carloforte’s Ligurian Tabarchino heritage, but it’s a separate, smaller town with its own distinct character.

What should I eat in Carloforte besides tuna and couscous?

Pesto and focaccia both appear on local menus in forms closer to their Genoese originals than typical Sardinian cooking, a direct legacy of the founding families’ Ligurian roots.
