Sardinia (Sardegna in Italian, Sardìnnia in Sardinian, pronounced Sar-deen-ya) is Italy’s second-largest island and its most culturally distinct. Sardinians speak Sardinian, cook a different cuisine from any mainland region, and treat their granite coastline and inland mountains as separate worlds. September is the honest month: sea at 24°C, crowds gone, Cannonau harvest in the villages.
Three stays we would book again.
Hotel Cala di Volpe, Porto Cervo
Jean Couzon’s 1962 architecture, the saltwater pool, and a bay that still deserves the Costa Smeralda invoice. Book a Junior Suite, not the base room.
€1,200–€3,400 / night
USD 1,300–3,700 · June to September
Su Gologone Experience, Oliena
Painted-tile courtyards in the Barbagia foothills. The best access point for Supramonte hikes, Tiscali and Cala Luna, and a kitchen serving pane carasau and porceddu the way Oliena grandmothers do.
€260–€520 / night
USD 285–570 · shoulder rates from April
Hotel Villa Las Tronas, Alghero
Turn-of-the-century seafront villa on its own promontory, twenty minutes’ walk from Alghero’s Catalan old town. Room 106 is the one with the wraparound terrace.
€340–€680 / night
USD 370–740 · April to October
Three practicalities that catch first-timers.
- Fly, do not ferry, unless you are bringing a car. Genoa to Olbia is 10 hours 30 minutes on the Tirrenia overnight from around €65; Ryanair Milan to Cagliari is 90 minutes from around €40. Ferry only wins if you need the car for Barbagia villages.
- The east coast beaches (Cala Goloritzé, Cala Mariolu, Cala Luna) are boat-access. Book the Cala Gonone morning departures; the afternoon sea builds and the return trip gets rough. Cala Goloritzé also caps daily arrivals at 250 people, book two weeks ahead in July and August.
- September beats August by every metric except sea temperature. Water still 23 to 25°C, prices 30 to 50 percent off peak, restaurants stop turning tables. The one exception: Ferragosto week (mid-August) if you want the village festivals.
