Sardinia is not merely an Italian island; it is a world apart, shaped by Nuragic civilizations, Phoenicians, Romans, Pisans, Aragonese rulers, and a proudly independent local identity that still shows in its language, food, and festivals. Over seven days, this itinerary introduces two excellent bases—Cagliari in the south and Olbia in the northeast—giving you history, city life, beaches, and the famous La Maddalena Archipelago without wasting time in transit.

One of Sardinia’s great pleasures is contrast. In a single week you can stand atop Cagliari’s limestone bastions, eat fregula with seafood near an old port, drive or ferry toward emerald coves in the north, and sail through water so clear it seems lit from below. The island is also full of memorable details: bottarga shaved over pasta, myrtle liqueur after dinner, flamingos in city wetlands, and granite landscapes that make the coast feel almost otherworldly.

Practically speaking, late spring through early autumn is best for swimming and boat trips, while shoulder season offers lighter crowds and easier restaurant reservations. Renting a car is useful in Sardinia, but this plan works with a mix of airport transfers, rail, taxis, and organized boat excursions; as always, reserve ferries, tours, and summer accommodations well ahead, carry sun protection, and expect many restaurants to dine later than in the U.S.

Cagliari

Cagliari is Sardinia’s capital and the island’s most layered city: Roman stones under Baroque domes, medieval towers above busy markets, and broad sea views beyond old quarter stairways. It feels lived-in rather than staged, which is exactly its appeal.

The heart of the city is Castello, the high old district wrapped in walls and views. Below it, Marina and Stampace are where you settle into the local rhythm—espresso at the counter, seafood lunches, aperitivo on narrow lanes, and long dinners that begin after sunset.

Food matters deeply here. Look for culurgiones, fregula ai frutti di mare, roast suckling pig in traditional spots, seadas drizzled with honey, and excellent seafood simply grilled with olive oil and lemon. For stays, browse VRBO in Cagliari for apartment-style options in Marina or Castello, or compare Hotels.com stays in Cagliari for polished hotels near the port and train station.

To reach your first Sardinian base, use Omio flights for Europe to compare routes into Cagliari Elmas Airport. From the airport to the center, the train is usually about 7 minutes to Cagliari station and inexpensive, while a taxi generally takes 15–20 minutes depending on traffic.

• Viator pick: Cagliari: A Full Meal Sardinian Food Tour with Do Eat Better — an excellent early-trip orientation to local flavors and historic streets.
• Viator pick: Catamaran tour stops bathing and snorkeling toast with prosecco — a compact way to see the Gulf of Angels and the Sella del Diavolo coastline from the water.

Day 1 – Arrive in Cagliari

Morning: This is your travel morning, so keep the schedule light and aim simply to arrive with energy intact. If you land early enough to drop bags before check-in, have your first coffee at a classic bar near Piazza Yenne—an espresso and a flaky pastry is the right introduction to southern Sardinia.

Afternoon: After arrival and hotel check-in, begin with an easy walk through Marina and up into Castello. See the Bastione di Saint Remy, whose grand staircase and terrace offer one of the city’s finest overviews, then continue toward the Torre dell’Elefante and Cagliari Cathedral, where layers of medieval and Baroque history sit side by side.

Evening: For dinner, book a table at Sa Domu Sarda for a classic introduction to regional cooking; it is especially good if you want dishes rooted in the island’s pastoral traditions rather than generic Italian standards. If you prefer seafood on night one, Antica Cagliari near the port is a reliable choice for mixed fish antipasti and pasta with clams, in a dining room that still feels tied to the old maritime city.

Day 2 – Markets, Castello, and Sardinian flavors

Morning: Start with breakfast at Caffè Libarium Nostrum, where the terrace views are almost unfairly beautiful in the early light. Then visit Mercato di San Benedetto, one of Italy’s most impressive covered food markets, to see Sardinia in edible form—gleaming fish counters, cheeses, cured meats, bottarga, and produce that tells you exactly what season the island is in.

Afternoon: Spend the afternoon exploring more of the historic center, including the Roman Amphitheatre area and the lanes of Stampace. For lunch, choose Su Cumbidu, known for hearty Sardinian fare such as malloreddus and roasted meats, or Sa Piola if you want a more informal meal with local character and good culurgiones.

Evening: Join the Cagliari food tour on Viator this evening if timing fits; it is particularly smart on your second day, once you can place the dishes and neighborhoods in context. If you prefer an independent evening, have aperitivo in Marina, then settle into a slower dinner ending with seadas and a small glass of mirto.

Day 3 – Poetto Beach and the Gulf of Angels

Morning: Begin with coffee and breakfast at Caffè De Candia or another central café, then head to Poetto Beach, Cagliari’s long urban strand. Even outside peak summer, it is worth visiting for the promenade, sea air, and the sense that this city never really turns its back on the coast.

Afternoon: Book the catamaran tour in the Gulf of Angels for a water-level view of the Sella del Diavolo, one of the city’s signature headlands. It is a fine complement to your historic days, and the swimming and snorkeling stops offer the kind of clear, bright Sardinian sea many travelers come for first and remember longest.

Evening: Stay near Poetto for dinner at a beachfront spot if you want a relaxed coastal mood, or return to town for something more traditional. Luigi Pomata is a strong choice for a more refined seafood dinner with Sardinian ingredients treated carefully rather than theatrically; if you want a simpler evening, choose a trattoria in Marina and order fregula with shellfish.

Day 4 – Travel from Cagliari to Olbia

Morning: Depart Cagliari in the morning for Olbia. The most practical public-transport option is to compare Omio train options in Europe; rail journeys are typically around 3.5 to 4 hours, often with a change, and fares commonly start around €18–€30 depending on schedule and booking window. Bus alternatives can be checked via Omio buses in Europe, though trains are usually more comfortable for this route.

Afternoon: Arrive in Olbia, check in, and spend your first hours getting acquainted with the compact center around Corso Umberto. Visit the Basilica of San Simplicio, an austere Romanesque church that hints at the city’s older layers before Olbia became known primarily as the gateway to the Costa Smeralda.

Evening: Dine in town at Trattoria Il Gambero for dependable seafood and a local atmosphere, or seek out a restaurant specializing in Gallurese cuisine, the regional style of northeastern Sardinia. If you like a gentle first-night stroll, the waterfront areas and evening passeggiata in central Olbia are easy and pleasant without demanding too much after transit.

Olbia

Olbia is often treated as a transit point, but that undersells it. Yes, it is a major gateway for flights and ferries, but it is also the key to northeastern Sardinia: Tavolara Marine Protected Area, Costa Smeralda villages, and departures for some of the island’s most cinematic seascapes.

The city itself is manageable and useful, which makes it an excellent base for a week that mixes urban comfort with excursions. In the center you have walkable streets, good restaurants, and enough history to anchor your stay; beyond it, granite hills, polished marinas, and radiant beaches spread outward in every direction.

For accommodations, compare self-catering stays on VRBO in Olbia or hotels on Hotels.com in Olbia. For onward regional transport and possible ferries around northern Sardinia, compare Omio ferry options in Europe where relevant, and use taxis or organized excursions for coastal points that are awkward by public transport.

• Viator pick: Olbia Catamaran Tour for Dolphin Research and Tavolara Marine Park — ideal if you want marine scenery beyond the Costa Smeralda postcard circuit.
• Viator pick: Olbia: Pasta and Tiramisu Class in a Local Home by Cesarine — a warm culinary counterpoint to beach and boat days.
• Viator pick: Small Group Costa Smeralda P. Cervo San Pantaleo Sardinia ITALY — useful for seeing polished resort scenery and inland artisan character without driving yourself.

Day 5 – Olbia old town and Tavolara waters

Morning: Have breakfast at a central café with a cornetto and cappuccino, then spend a little time in the old town before heading to the coast. If you prefer a slow start, browse local shops along Corso Umberto and keep the morning intentionally light so the sea excursion becomes the day’s centerpiece.

Afternoon: Join the Olbia catamaran tour for Tavolara Marine Park. This outing is especially attractive because it trades crowded shoreline hopping for protected marine scenery, with striking limestone massifs, transparent water, and the possibility of dolphin-focused interpretation depending on the operator and conditions.

Evening: For dinner, look for a restaurant serving Gallurese dishes such as zuppa gallurese, the baked bread-and-cheese specialty that is far more delicious than its plain description suggests. If you want something lighter after a boat day, choose grilled local fish, a tomato salad, and Vermentino, the white wine that seems almost designed for Sardinian evenings.

Day 6 – La Maddalena Archipelago day trip

This is the day to devote to northern Sardinia’s signature seascape. From Olbia, take an early transfer or drive toward Palau or Cannigione—roughly 45 minutes to 1 hour depending on departure point and traffic—then spend the day in the La Maddalena Archipelago, where pale granite, turquoise channels, and protected islands create the kind of scenery that made Sardinia famous well beyond Italy.

For this day, choose one boat experience that suits your style. Excellent options include the La Maddalena Archipelago Sailing Tour with Lunch from Palau, the Catamaran tour Magdalene Archipelago from Cannigione, or, if you want a more elevated onboard setup, the Magdalene Archipelago Catamaran Tour from Porto Cervo - Luxury 4. Expect swimming stops, dazzling water, and a perspective on Sardinia that simply cannot be replicated from land.

Back in Olbia in the evening, keep dinner simple and restorative. A plate of pasta with bottarga or clams and a final mirto is enough; after a full day under sun and salt air, Sardinia tends to make minimalism feel like wisdom.

Day 7 – Costa Smeralda or cooking class, then departure

Morning: With a later afternoon departure, you have time for one last well-chosen experience. If you want scenery, book the Small Group Costa Smeralda and San Pantaleo tour, which works well for travelers curious about the contrast between Porto Cervo’s polished resort world and the more rooted artisan atmosphere of inland villages.

Afternoon: If you would rather spend your last hours indoors and deliciously, choose the pasta and tiramisu class in a local home, a lovely farewell to the island’s hospitality. Otherwise, enjoy a final lunch in Olbia—fresh seafood, pane carasau, and a last glass of Vermentino—before making your way to the airport for departure.

Evening: This is your departure window. For flights out of Olbia, compare schedules on Omio; Olbia Costa Smeralda Airport is usually a short taxi ride from the center, often around 10–15 minutes depending on traffic.

In seven days, this Sardinia itinerary gives you a satisfying slice of the island without rushing past what makes it distinct: ancient urban layers, serious food culture, and some of the Mediterranean’s most striking water. Cagliari grounds the trip in history and flavor, while Olbia opens the door to northeastern coastlines, Tavolara, and the unforgettable La Maddalena Archipelago.
