Seven days is the right length for a first Sardinian road trip if you treat the island as three bases, not thirty stops: two nights in Cagliari for the old bastions and Poetto's long sand, two in Alghero for the Catalan lanes, the Grotte di Nettuno and La Pelosa, and two in Olbia with the Costa Smeralda's coves on your doorstep. The drives between them are the scenic connective tissue, about three hours each, and nothing on this route needs a ferry or a toll booth.

Expert-curated: every place is real, planned with the same verified data Robin uses in the app and curated with local experts. How these itineraries are made
Getting around: 1.8 km on foot (~23 min) · 3 short rides
A full Cagliari day: the cathedral and archaeological museum in the cool morning, then a picnic carried down to Poetto beach for a swim, closing with the cliff walk at Sella del Diavolo as the light turns.
Day 3: The drive to Alghero and its Catalan old town
Getting around: 610 m on foot (~8 min)
Move day to Alghero, the drive is mid-morning, so you'll arrive with the whole afternoon free to wander the Catalan old town and watch the sunset from the ramparts.
Alghero's classic seafood house on the port, known for its aragosta alla catalana.
Choose how you eat on the road
If you like leaving lunch to luckkeep the loose midday slots as they are: park where a town looks good and follow the locals, the interior villages reward it
If you want every meal named in advanceask Robin to pin a specific trattoria for the two open lunch slots on the move days, so nothing is left generic
If you would rather be on the beach by onerepeat the day-2 trick: pick up panadas and pane carasau in the morning and picnic where you land

Tiny, well-loved Alghero spot serving refined takes on Sardinian classics, the splurge-worthy dinner of the trip.
Robin's tip. The Escala del Cabirol down to the Grotte di Nettuno is 654 steps each way. Take the morning boat from Alghero instead if knees are a concern, and check sea conditions the evening before, as swells cancel it.

A day mixing ancient stones and glamorous coast: a nuraghic tomb near Olbia in the morning, then Porto Cervo and a swim at one of the Costa Smeralda's loveliest beaches.
A final unhurried stroll through the historic center's quiet stone streets before heading onward.

Bucket-list foods in Cagliari
Malloreddus alla campidanese
Sardinia's little saffron gnocchetti in sausage and tomato sugo, the island's definitive first course.
On this trip: Trattoria Lillicu, day 1 dinner, a Cagliari institution since the 1950s
Fregola con arselle
Toasted pearl pasta with tiny clams, the Cagliari classic that tastes like the lagoon it comes from.
On this trip: Ristorante Sa Piola, day 2 dinner in the Marina district
Culurgiones
Hand-pleated pasta parcels of potato, pecorino and mint, each one closed like an ear of wheat.
On this trip: Ristorante Gallura, day 5 dinner in Olbia
Porceddu
Suckling pig roasted slowly over juniper wood until the skin crackles, the great inland feast dish. This route stays coastal, so ask Robin to swap in an agriturismo dinner and it will find you one.
Where to stay for this itinerary
Stay in Cagliari: Castello or the Marina quarter if…
you want the bastion views and the old town outside your door
eating well matters most on nights one and two, the Marina's trattorias are steps away
Stay in Alghero: inside the Centro Storico if…
you want the ramparts and the sunset walk without driving
two nights of Catalan-Gothic lanes and seafood sounds like the heart of the trip
Stay in Olbia: the old town, not the resort coast if…
you'd rather drive 30 minutes to the Costa Smeralda's beaches than pay its hotel prices
an evening passeggiata and an honest culurgiones dinner beat a resort buffet
Before you go
Do you really need a car?
Yes. The three bases are linked by long cross-island drives, and the best of the trip (Nuraghe Palmavera, La Pelosa, Liscia Ruja) is reachable only by road. The driving itself is easy: quiet roads, no tolls, no ferries.
What must be booked ahead?
La Pelosa caps beach access in high season, so reserve before you go. The Grotte di Nettuno boat runs on sea conditions, so check times the day before. Book the Al Tuguri dinner in Alghero a few days out; it is tiny.
Which airports does this route use?
Fly into Cagliari and out of Olbia; both have their own airports and the open-jaw shape saves you a three-hour drive back south. Most rental companies on the island allow one-way rentals between the two, for a fee worth paying.
Is seven days enough?
For the south, the northwest and the Costa Smeralda, comfortably. What it leaves out is the wild east coast around Cala Gonone and the giant nuraghe at Barumini, which are the first things to add with more time.
When should you go?
Late May to June has warm sea, long light and open restaurants without the August crush. September is the sleeper pick: the water is at its warmest and the beaches empty out.
9–10 days
Have 9–10 days?
First, add Barumini between Cagliari and Alghero
Su Nuraxi at Barumini is the grandest nuraghe on the island and sits nearly on the day-3 route. Break the drive there, then carry on north with the whole civilization fresh in your head.
Give Olbia a boat day
From Palau, half an hour north, ferries and small boats loop the La Maddalena archipelago. Its granite islets and coves are the best swimming of the whole trip.
Finish on the east coast
Two nights at Cala Gonone opens the Golfo di Orosei: boat-only beaches like Cala Luna under limestone cliffs, a wilder closing act than the Costa Smeralda.
