Sardinia is often introduced through its beaches, but the island’s deeper story is older and stranger than most first-time visitors expect. Phoenicians, Carthaginians, Romans, Pisans, Aragonese rulers, and the House of Savoy all left marks here, while the island’s mysterious Nuragic civilization predates much of classical Mediterranean history. In one week, you can move from fortified hilltop quarters and Roman remains to transparent coves that look almost unreal.

It is also an island of strong local identity. Sardinian cuisine differs notably from mainland Italy: expect culurgiones dumplings, fregola with shellfish, bottarga, porceddu, pane carasau, and wines such as Vermentino and Cannonau. Even the landscapes change dramatically between south and northeast, which is why this itinerary pairs Cagliari and Olbia for a balanced first journey.

Practical notes matter in Sardinia. A rental car gives the greatest freedom, but for this 7-day trip you can comfortably combine city stays, guided boat excursions, and a train between Cagliari and Olbia. Weather from late spring through early autumn is ideal for swimming and sailing; in peak summer, reserve accommodations, ferries, and beach clubs well ahead, carry sun protection, and book early starts to avoid midday heat and traffic.

Cagliari

Cagliari, Sardinia’s capital, rises above the Gulf of Angels in layers: a waterfront of palms and port activity, elegant shopping streets, and the walled Castello district perched high above the sea. It feels lived-in rather than staged, which is part of its appeal. Flamingos gather in nearby wetlands, Roman stones sit beneath modern life, and sunset arrives with a wide, golden sweep over domes, bastions, and water.

This is the right city for travelers who want history with their beach time. The old quarters of Castello, Marina, Stampace, and Villanova each offer a different mood, from aristocratic facades to market lanes and wine bars. Cagliari is also one of the island’s best places to begin understanding Sardinian food beyond the postcard staples.

Getting there: For flights into Sardinia from Europe, compare routes on Omio flights. Cagliari Elmas Airport is roughly 10-15 minutes by taxi from the center, or about 7 minutes by train to Cagliari station once you are landside. Typical airport transfer costs are about €2-3 by train or €20-25 by taxi.

Recommended activity in Cagliari: The Cagliari: A Full Meal Sardinian Food Tour with Do Eat Better is an excellent first-evening orientation to local dishes and neighborhoods.

For time on the water, the Catamaran tour stops bathing and snorkeling toast with prosecco offers a relaxed view of the Sella del Diavolo coastline from the sea.

Another strong option is the Cagliari boat tour : 5 swim stops, snorkeling & Sardinian aperitif, especially if you want a longer coastal outing.

Day 1 - Arrive in Cagliari

Morning: In transit to Sardinia. If you have flight choices, aim for an arrival that gets you into town by mid-afternoon so your first evening feels unhurried rather than lost to logistics.

Afternoon: Check in and take a gentle orientation walk through the Marina district and up toward Bastione Saint Remy. This is one of Cagliari’s signature viewpoints, a grand terrace built into the city’s historic fabric, and it gives you the kind of first panorama that explains the geography of the place in a single glance.

Evening: Start with aperitivo at Libarium Nostrum in Castello, known for its terrace views and strong sunset timing. For dinner, book Antica Cagliari for classic seafood in a handsome historic setting; if you want something more market-driven and contemporary, Sa Piola offers Sardinian dishes in a convivial old-town atmosphere. If energy remains, stroll Via Roma and the port before turning in.

Day 2 - Castello, Roman Cagliari, and a deep dive into Sardinian food

Morning: Begin with coffee and breakfast at Caffè Svizzero, one of the city’s old names, then climb into Castello to visit the Cattedrale di Santa Maria, the Torre dell'Elefante area, and the lanes around Piazza Palazzo. These streets are best appreciated early, before the stone radiates heat and before the day-trippers thicken the viewpoints.

Afternoon: Explore the Roman Amphitheatre area and the Orto Botanico, which makes a pleasing contrast after the fortified upper town. For lunch, head to Su Cumbidu, where you can try traditional Sardinian plates such as culurgiones or malloreddus in a space that feels rooted in the island rather than polished for outsiders.

Evening: Join the Cagliari: A Full Meal Sardinian Food Tour with Do Eat Better. This is a smart early-trip choice because it teaches you the local vocabulary of flavors: pane carasau, cured meats, seafood preparations, sweets, and wines you will keep seeing throughout the week.

Day 3 - Poetto Beach, flamingos, and the Gulf of Angels

Morning: Have breakfast at Caffè De Candia or a quick pastry and espresso near your hotel, then head to Poetto Beach. The long urban strand is part local institution, part seaside promenade, and it shows Cagliari’s daily rhythm better than any monument. If you like a walk before swimming, continue toward the Molentargius-Saline Regional Park area, where pink flamingos are regularly seen in the wetlands.

Afternoon: Take the Cagliari boat tour : 5 swim stops, snorkeling & Sardinian aperitif or, if you prefer a shorter outing, the catamaran tour with snorkeling and prosecco. Seeing Sella del Diavolo from the water gives the coast its proper scale, and the swim stops are a fine way to enjoy the south without renting a car.

Evening: For dinner, reserve a table at Luigi Pomata, one of Cagliari’s most respected addresses, especially if you enjoy tuna and refined Sardinian seafood. If you want something livelier and less formal, Martinelli’s offers a polished city-center dinner, while a simple post-boat gelato and passeggiata along Via Manno makes for an equally good ending.

Day 4 - Travel from Cagliari to Olbia

Morning: Depart Cagliari for Olbia. The most practical public transport option is a direct or near-direct train booked via Omio trains; journey time is usually about 3 hours 30 minutes to 4 hours, with fares commonly around €18-30 depending on service and booking window. If schedules suit you better, compare buses on Omio buses, though rail is generally the smoother choice.

Afternoon: Arrive in Olbia, check in, and explore the compact historic center around Corso Umberto I, the Basilica of San Simplicio, and the waterfront. Olbia is often treated as a transit point for Costa Smeralda, but that undersells it; the town itself is convenient, walkable, and full of good places to eat without the price inflation of the resort enclaves.

Evening: Have dinner at Trattoria Il Gambero if you want reliable seafood in a traditional style, or try La Lanterna for a comfortable local dinner in town. For a relaxed first evening, finish with a glass of Vermentino at a wine bar near the center and get some rest before tomorrow’s longer day on the water.

Olbia

Olbia is the northeastern gateway to some of Sardinia’s most coveted scenery: Costa Smeralda, Palau, Cannigione, Golfo Aranci, and the luminous islands of La Maddalena. Yet the city is more than an arrival point. It has Roman and medieval traces, a proper local food scene, and a practical base that spares you the resort premium while keeping beaches, ports, and excursions within easy reach.

What makes this area special is the quality of the water and the diversity of day trips. One day can be devoted to polished seaside villages and granite landscapes; the next can be spent under sail in marine park waters of improbable blues and greens. For a 7-day Sardinia itinerary, Olbia gives you the island’s cinematic northeast without overcomplicating the route.

Recommended activities near Olbia: For northeast highlights by land, consider the Small Group Costa Smeralda P. Cervo San Pantaleo Sardinia ITALY.

For a hands-on culinary experience, the Small group Pasta and Tiramisu at Local Home in Olbia is a warm, personal way to learn classic techniques.

For the archipelago, choose a sailing or catamaran day such as the Catamaran tour Archipelago Maddalena (lunch included) or the La Maddalena Archipelago Sailing Tour with Lunch from Palau.

Day 5 - Costa Smeralda and village life beyond the glossy postcard

Morning: Start with breakfast at Caffè Cosimino or a central pasticceria in Olbia, then set out for the Small Group Costa Smeralda P. Cervo San Pantaleo Sardinia ITALY. This is the easiest way to understand the northeast’s contrasts: Porto Cervo’s polished marinas and designer facades, the granite inland atmosphere of San Pantaleo, and lookout points where the sea appears almost electrically bright.

Afternoon: Continue the excursion, or if going independently, focus on one or two spots rather than racing through many. San Pantaleo is especially worth time because it offers a more rooted Sardinian feel than the resort coast, with stone houses, artisan shops, and a mountain backdrop that softens the glamour of Costa Smeralda.

Evening: Return to Olbia for dinner at Officina del Gusto, a good choice if you want a more modern plate and wine list, or seek out a pizzeria if you prefer a lighter evening after a full touring day. End with a harbor-side walk; Olbia by night is calm, practical, and pleasantly local.

Day 6 - Full-day La Maddalena Archipelago sailing

Dedicate today to the La Maddalena Archipelago, one of the great highlights of any Sardinia travel guide. From Olbia, plan an early transfer to Palau or Cannigione, usually around 40-50 minutes by car or taxi depending on your departure port. Book either the Catamaran tour Archipelago Maddalena (lunch included), the La Maddalena Archipelago Sailing Tour with Lunch from Palau, or, if you want a premium feel, the Catamaran tour Magdalene Archipelago from Cannigione from 12 mt..

The reward is a full day of translucent water, pale granite, and coves that have made northern Sardinia famous. Bring reef-safe sun protection, a hat, and dry clothes for the return. Expect swimming and snorkeling stops in protected areas where the clarity of the water is the main event. Lunch on board is part of the pleasure; this is a day to surrender your schedule to the sea.

After returning to port and back to Olbia, keep dinner simple. A plate of spaghetti ai frutti di mare or grilled catch of the day in town is ideal after salt, sun, and wind.

Day 7 - Olbia old town, a final taste of Sardinia, and departure

Morning: Ease into the last day with breakfast and a final wander through Olbia’s center. If your departure timing allows and you want one more structured experience rather than beach time, book the Small group Pasta and Tiramisu at Local Home in Olbia. It is a memorable closing note because it trades scenery for hospitality and sends you home with actual culinary technique.

Afternoon: Transfer to Olbia Costa Smeralda Airport for departure. For flights within or from Europe, compare options on Omio flights. The airport is roughly 10-15 minutes from central Olbia by taxi, generally around €15-20 depending on traffic and luggage.

Evening: In transit home, ideally with a bottle of Vermentino packed safely in checked luggage and a new inability to look at ordinary shades of blue with any respect.

This 7-day Sardinia itinerary balances the island’s essentials without trying to conquer all of it at once. Cagliari gives you history, markets, and southern seascapes; Olbia opens the door to Costa Smeralda and the dazzling La Maddalena Archipelago. Together they make a first trip that feels broad, flavorful, and gloriously unfinished in the best possible way.
