Sardinia Itinerary 10 Days: Two Bases, Costa Smeralda + Alghero

Is 10 days enough time to see Sardinia properly?

Yes. Ten days is the sweet spot: enough to use two bases, see Costa Smeralda and Alghero, do two boat days, add inland culture without burnout.

Sardinia is the second-largest Mediterranean island. A 7-day trip forces you to pick one coast. A 10-day trip covers both the Emerald Coast and the Catalan west around Alghero without rushing. The 6+4 night split gives two settling-in experiences plus a scenic transfer day. Fourteen days adds a southern loop through Cagliari; 10 days is the longest trip that doesn't require a third base.

Should a 10-day Sardinia trip use two bases?

Yes. Splitting 6 nights Olbia + 4 nights Alghero cuts daily drive times in half and unlocks Neptune's Grotto, Bosa, and the Sinis Peninsula.

A single base in Olbia for 10 days means Neptune's Grotto becomes a 5-hour round-trip and Bosa 6 hours. Splitting 6+4 reduces the longest day to 90 minutes each way. The only cost is a Day 7 pack-up and 2.5-hour transfer, which we turn into a scenic stop in Castelsardo for lunch. For anything under 9 days, stay in one base. For 10 days or more, split.

Should a 10-day Sardinia itinerary include Cagliari?

No. Cagliari sits 270 km south of Olbia and adds two transfer days; for 10 days stick to Olbia + Alghero.

Adding Cagliari means a 3-hour drive south and a 3-hour return, eating roughly 2 days. The south (Cagliari, Villasimius, Costa Rei, Chia) is worth a dedicated 5-to-7-day return trip with its own flights and car. A 10-day northern itinerary is a complete trip; the south is a different Sardinia.

How far is Alghero from Olbia by car?

Alghero is about 140 km from Olbia, 2 hours via SS131 or 2.5 hours via the scenic northern coast through Castelsardo.

The direct SS131 Nuoro route is faster but dull. Our recommended Day 7 transfer goes north via the SS199 to Castelsardo, then west on the SS200 into Alghero. The extra 30 minutes buys you a medieval hilltop town, fortress ramparts, and a trattoria lunch. With a lunch stop the total is roughly 3 hours including walking.

Which airport should I fly into for a 10-day Sardinia trip?

Fly into Olbia Costa Smeralda (OLB) and out of Alghero Fertilia (AHO), an open-jaw booking; saves the 2-hour return transfer.

Most airlines serving Sardinia (Ryanair, easyJet, ITA, Lufthansa, British Airways) offer open-jaw bookings at similar cost to round-trip. Check rental car one-way drop fees: most companies charge €40-60 for Olbia-to-Alghero one-way, cheaper than the fuel and time of returning. Confirm the drop fee before booking.

Is a rental car required for a 10-day Sardinia itinerary?

Yes. A rental car is required; beaches, nuraghi, and villages are spread out with limited public transport.

Trains connect Olbia to Cagliari and limited buses reach Alghero, but nothing reaches Costa Smeralda beaches, La Prisgiona, Cantina Surrau, Bosa, the Sinis Peninsula, or Capo Caccia. Expect 900-1,100 km total over 10 days (only 60-70 km per travel day, since boat and slow days drive very little).

What's the best time of year for a 10-day Sardinia trip?

Late May to mid-July and September to mid-October: warm sea, lower crowds than August, open restaurants and boat operators.

August is 2x-3x peak pricing with full beaches and 2-week minimum stays. Early June and mid-September are operator favorites: sea above 22 degrees, restaurants open, La Maddalena boats daily. Late October closes shoulder-season operators; November to April is off-season with cool swimming but excellent trail and city weather.

How much does a 10-day Sardinia trip cost per person?

Budget €680-880 per person excluding accommodation and flights, covering car rental, fuel, 2 boat days, wine, restaurants, park fees.

Our estimate assumes 2 adults sharing a compact car, mid-range restaurants (€25-35 per dinner), and mid-tier boat operators. August prices run 15-25% higher. Accommodation adds roughly €1,100-1,900 per couple for 10 nights in shoulder season across the two bases.

Is a 10-day Sardinia itinerary good for families with kids?

Yes. The two-base model reduces daily car time; swap Bosa's long drive for a second Alghero beach day with children under 8.

Tavolara (Day 4) is a better first boat day than La Maddalena for younger kids: smaller boats, shorter crossings, more snorkeling. The 2.5-hour Day 7 transfer is best split with a long Castelsardo lunch and playground break. If your kids are under 5, consider a single-base 10-day plan from Olbia and skip the western transfer.

Can I do a 10-day Sardinia trip without renting a car?

Partially. Base in Olbia using buses plus a La Maddalena boat, then train-bus to Alghero; you'll miss Sinis Peninsula and Vermentino country.

Trenitalia and ARST buses link Olbia to Alghero via Sassari (4 hours, €20 pp). From Alghero, public buses reach Bosa (1 hour) and Capo Caccia for Neptune's Grotto (25 minutes). Boat from Alghero port avoids the stairs. You lose about 30% of the itinerary without a car. Most guests rent a small compact for €180-250 over 10 days, cheaper than missed experiences.

Should I start a 10-day Sardinia trip in Alghero or Olbia?

Olbia first. Starting east lets you acclimate with shorter drives, do boat-heavy days, then transition west for a slower second half.

The east coast is more activity-dense (boats, multiple beach areas, nuraghi). Doing it first while energy is high works well; the west coast is more contemplative (one grotto, one coastal drive, one Catalan old town) and pairs naturally with the end of a trip. The Day 7 direction also matches most departure schedules, with Alghero's morning outbound options.

Is Bosa worth the day trip from Alghero?

Yes. Bosa is 45 km south along one of Sardinia's most scenic coastal roads; pastel village plus Malvasia tasting is a trip highlight.

The SP105 coastal road is a National Geographic-listed drive with seven named overlooks in 50 km. Bosa has a medieval castle, a pastel old town along the Temo River, and the rare indigenous Malvasia di Bosa DOC wine. Plan 8 hours door-to-door from Alghero: slow drive down, lunch at Ponte Vecchio, castle climb, wine tasting, sunset drive home.
