Best beaches in south Sardinia

A coast built for a car and a day plan, not a single resort

The south coast fans out from Cagliari in two directions — west towards Chia and Teulada, east towards Villasimius and Costa Rei — and neither stretch is walkable from the other. Most visitors base themselves in the city or in one of the beach towns and pick a direction each day rather than trying to see everything from a single hotel. This guide runs through the main beaches in driving-time order from Cagliari, with what each one is actually good for, because “best beach in the south” changes depending on whether you want dunes, calm snorkelling water, or somewhere five minutes from a bus stop.

Beach	Distance from Cagliari	Best for	Quota / booking
Poetto	In the city	No-car days, evening swims	None
Chia (Su Giudeu)	50 min	Dunes, scenery	None on Su Giudeu itself
Tuerredda	55 min	Turquoise water	Yes, capped July-August
Nora beach	35 min	Ruins plus a swim	None
Villasimius (Simius)	50 min	Snorkelling, families	None
Costa Rei	60 min	Long sand, fewer crowds than Chia	None

Poetto: the beach you don’t need a car for

Poetto, Cagliari’s own beach, is the one genuine advantage the south has over any other region: 8km of pale sand a 20-minute bus ride from the historic centre, running from the Sella del Diavolo headland to Quartu Sant’Elena. It’s a working city beach rather than a resort — sun loungers cost €10-15 a day at the licensed stabilimenti, but long stretches are free and unmanaged if you bring your own umbrella. It gets busy with locals in July and August evenings rather than tourist crowds during the day, and the water is calm and shallow enough for children close to shore. See our full Poetto beach guide for which stretch to pick.

Chia: the south’s best combination of dunes and water

Chia is 45 minutes to an hour south-west of Cagliari and worth the drive for the scenery alone — dunes up to 40m tall back several of the beaches, and a 16th-century Spanish watchtower sits on the headland above Su Giudeu. The area actually covers four or five separate coves within a short drive of each other: Su Giudeu and Sa Colonia are the widest and most family-friendly, while Tuerredda, a little further south towards Teulada, is the postcard one — pale sand, turquoise shallows, and consequently a** capped daily entry quota** in July and August that fills by mid-morning.

Book ahead through the municipal system if Tuerredda is non-negotiable for your trip; our Chia beaches guide and Tuerredda beach guide both cover the current booking process, and Sardinia’s beach access quotas rounds up every capped beach on the island in one place.

If you’d rather not drive and want the whole area covered in one outing, the full-day guided beach tour to Chia and Tuerredda takes in both, or the more flexible van tour of the Chia beaches if you want the driver to adjust the stops on the day. For a different angle on the same coastline, the quad adventure from Chia gets you inland through the dune trails between beaches, which a standard beach tour skips entirely.

Nora: ruins with a swim attached

At Pula, roughly 35 minutes from Cagliari, Nora pairs a Roman-Punic archaeological site directly on a headland with genuinely swimmable coves either side — you can walk the mosaic floors of the ancient theatre in the morning and be in the water by lunch. It’s less about beach quality on its own and more about efficiency: no other stop on this coast combines history and sea in one visit this well. Our Nora archaeological site guide has opening hours and the combined ticket that covers both the ruins and the small museum in Pula.

Villasimius and the Capo Carbonara marine reserve

East of Cagliari, Villasimius trades Chia’s dune drama for calmer, clearer water, largely because the Capo Carbonara area is a protected marine reserve with restrictions on boat anchoring near the reef. That makes it the better pick in the south for snorkelling — see diving at Villasimius and Capo Carbonara for operators — and for families who want gentler entry than Chia’s more exposed coves. Villasimius beach itself and the smaller Porto Giunco cove, backed by a lagoon that sometimes hosts flamingos, are both easy walks from the town.

The Villasimius and Solanas beaches tour from Cagliari is the straightforward way to see both without driving yourself, and the 4x4 tour to Villasimius’s hidden beaches reaches a handful of smaller coves along dirt tracks that a rental car generally can’t or shouldn’t attempt. Full write-up of the town and its beaches is in Villasimius beaches guide.

Costa Rei: the long-sand alternative when Chia is full

Further east again, an hour from Cagliari, Costa Rei is a straightforward long sandy beach without Chia’s dune backdrop, but it’s wide enough that it rarely feels as packed in August, and the water shelves gently. It suits anyone staying on the eastern side of the south coast who doesn’t want the extra 20-30 minutes back to Chia, or who prefers a resort-style beach with more facilities strung along it.

Hidden coves for anyone who’s done the main beaches already

If you’ve covered Chia, Villasimius and Poetto and want somewhere with fewer people, the coastline between Chia and Teulada hides several coves only reachable on foot or by 4x4 track. The hidden beaches jeep tour and the quad tour of hidden beaches from Domus de Maria both specialise in exactly this — small unmarked bays that don’t appear on the standard beach map and see a fraction of Chia’s crowds even in peak season.

Muravera and the Sarrabus: the south’s least-visited stretch

East of Villasimius and Costa Rei, the coastline around Muravera and the Sarrabus sees a fraction of the traffic that Chia and Villasimius get, largely because it’s a further drive from Cagliari — closer to 70-80 minutes — and doesn’t have a single headline beach to draw the crowds. What it does have is a string of smaller, quieter coves backed by citrus groves rather than dune scrub, and noticeably easier parking even in the second half of August. It’s worth the extra distance for anyone who has already done Chia and Villasimius and wants a genuinely local day out rather than another well-photographed beach.

Eating and staying near the south coast beaches

Chia and Villasimius both have a reasonable spread of restaurants geared toward beach days — expect simple grilled fish, fregola with clams, and the usual pizza options at the more casual end. For something more authentic, the inland villages just behind the coast, reachable in 10-15 minutes, tend to have better value trattorie than the beachfront strips themselves. Accommodation ranges from campsites and agriturismi inland to beachfront hotels directly on Chia and Villasimius; our hotel versus agriturismo in Sardinia comparison covers which suits a beach-focused stay better, and where to stay in Sardinia has the wider picture for planning a base.

Photography and the best light on this coast

Chia’s dunes photograph best in the first and last hour of daylight, when the low sun picks out the ridgelines and the watchtower on the headland casts a long shadow across the sand — arrive at golden hour if a good photo matters more than beach time itself. Villasimius and Porto Giunco work well at midday too, since the appeal there is the water colour rather than dune texture, and the marine reserve’s clarity holds up even in flat, overhead light. For anyone planning a trip partly around photography, Sardinia’s best photography spots has a wider list across the whole island, not just the south.

Combining beach days with the south’s archaeology and wine

The south coast isn’t only beaches — Barumini’s Su Nuraxi, Sardinia’s only UNESCO site, sits under an hour from Chia and Villasimius, and pairs naturally with a beach afternoon if you split the day between the two. Closer still, the vineyards around Villasimius and the Sarrabus produce some of the south’s better Cannonau, and several agriturismi in the area offer tastings that work as a relaxed alternative to another full beach day.

Our Su Nuraxi Barumini guide and Cannonau wine guide cover both in more depth than fits here, and either makes a strong half-day break from a beach-only itinerary, particularly useful if the wind picks up and swimming conditions turn marginal for a day.

Weather and sea conditions through the season

The south coast’s beaches are relatively sheltered compared with the more exposed Costa Smeralda and Gulf of Orosei, which makes them a safer bet on days with a stronger breeze. May and early June bring warm air but a sea that hasn’t fully caught up yet — expect the water to sit around 20-22°C rather than the 24-26°C of July and August.

September is genuinely the best month for this coast: the crowds from Chia and Villasimius thin noticeably after the first week, water temperatures stay close to their August peak, and restaurant bookings that required planning in summer become straightforward again. Our Sardinia in September and best time to visit Sardinia guides go into the month-by-month detail for the whole island, not only the south.

Lifeguards, safety and practical basics

Lifeguard cover on the south coast’s main beaches runs from mid-June to mid-September at the licensed stabilimenti sections of Poetto, Chia and Villasimius, though the free, unmanaged stretches often have none — worth knowing if you’re swimming with children away from a flagged zone. Flag colours follow the standard Italian system: green for safe conditions, yellow for caution, red for no swimming, most relevant on windier days at the more exposed Chia coves than at the sheltered Poetto or Villasimius bays. Pharmacies in Chia, Villasimius and along the Cagliari waterfront stock the basics for sunburn and stings; jellyfish appear occasionally in late summer but are rarely a serious problem on this stretch of coast.

Getting to these beaches without a rental car

Poetto aside, the south coast’s beaches are genuinely difficult without a car, and the honest options are a guided tour, a taxi, or the ARST regional bus network, which does run routes toward Chia, Villasimius and Pula but on a schedule built around local commuters rather than beach-day timing — expect one or two departures each way rather than a convenient shuttle every hour. A taxi from Cagliari to Chia runs somewhere in the €60-80 range one-way depending on traffic and time of day, which makes it worth splitting across a group rather than for a solo traveller, and rarely cheaper than simply joining one of the guided beach tours listed above once the return trip is factored in.

For a fuller picture of what’s realistic across the whole island without a hire car, see visiting Sardinia without a car and public transport in Sardinia, both of which cover the ARST network and its real limitations in more depth than fits here. A hire car booked for even two or three days specifically to cover the beach-heavy part of a south-coast trip, rather than for the whole stay, is often the more sensible middle ground between full-time car hire and relying entirely on buses and taxis.

Frequently asked questions about beaches in south Sardinia

Is Chia or Villasimius better for a first visit?

Chia for scenery and dunes, Villasimius for calmer swimming and snorkelling. If you only have one day free, Chia is the more photogenic and more talked-about choice, but Villasimius suits families with younger children better.

Do I need to book Tuerredda beach in advance?

In July and August, yes — it has a capped daily quota that fills by mid-morning. Outside peak season, no booking is needed. See Sardinia’s beach access quotas for the current process.

Can I visit south Sardinia’s beaches without a car?

Poetto, yes, easily, by city bus. Chia, Villasimius, Nora and Costa Rei are all much easier with a car or a guided tour — public buses run but with limited frequency. See visiting Sardinia without a car for what’s realistic.

How far is Chia from Cagliari airport?

About 45 minutes’ drive, roughly 50km, via the SS195 coast road.

Is Poetto beach free?

Yes — the shoreline is public. Sun loungers and umbrellas at the licensed stabilimenti cost roughly €10-15 a day if you want them; long stretches are unmanaged and free to use with your own gear.

Which south Sardinia beach is best for snorkelling?

Villasimius, specifically around Capo Carbonara, thanks to its marine protected area status and clearer water than the more exposed Chia coves. See diving at Villasimius for operators and sites.

What’s the quietest beach in the south?

The unnamed coves reached by 4x4 or quad tours between Chia and Teulada see far fewer visitors than the named beaches — see our quiet beaches in Sardinia guide for more across the whole island, not only the south.
