Chia sits southwest of Cagliari, and it offers a genuinely different coastal character than the beach towns closer to the capital — dune systems, a lagoon, and a much quieter, less built-up feel than Villasimius on the opposite side of the region. If you’ve read our guides to Cagliari and the best beaches near Cagliari, this is the deeper look at Chia itself.
A Coastal Area, Not a Conventional Town
Chia isn’t a standalone town in the way Villasimius is — it’s a coastal area within the municipality of Domus de Maria, spread across beaches, dunes, and a scattering of accommodation rather than centered on a dense town core. Worth knowing before you go: don’t expect a compact walkable center with a main street of shops and restaurants. Chia’s character is more spread out and more coastal-first than town-first.
The Beaches
Chia’s coastline includes several distinct beaches worth knowing individually rather than treating as one continuous stretch.
Sa Colonia
Sa Colonia sits beneath the Torre di Chia promontory, giving it one of the area’s most recognizable settings. Its position near the lagoon and tower makes it a practical choice for travelers who want to combine beach time with Chia’s landscape and history.
Su Giudeu
A small island sits just offshore here, close enough to swim or wade to depending on conditions, giving Su Giudeu a distinctive look and a natural point of interest beyond simply lying on the sand. Only approach the islet when sea conditions make it safe to do so — currents and swell can change quickly, and it’s not a crossing to attempt in rough water.
Cala Cipolla
Smaller and more sheltered than the open stretches nearby, Cala Cipolla has a cove-like feel with rockier edges framing the sand — a reasonable choice if you want something a bit more enclosed than Chia’s bigger beaches.
Monte Cogoni
Monte Cogoni lies beside the Stagno di Chia, with the lagoon immediately behind the beach. That setting makes it one of the better places to appreciate how Chia’s wetlands, sand and coastline fit together, with possible flamingo sightings when seasonal conditions are suitable.
The Lagoon and Flamingos
Behind Chia’s beaches sits the Stagno di Chia, a lagoon that forms one of the area’s defining features alongside the dunes. Flamingos may be seen here when water levels and seasonal conditions are suitable, similar to other wetland areas along Sardinia’s coast — but this isn’t a guaranteed sighting, and exact timing shifts from year to year depending on conditions. Treat it as a genuine possibility worth keeping an eye out for during your visit, not a scheduled attraction.
Torre di Chia
A coastal watchtower, the Torre di Chia looks out over the beaches and dunes below, one of several such towers built along Sardinia’s coastline historically as part of a broader coastal defense network. It’s worth the short visit for the vantage point alone — from up here, the relationship between the dunes, the lagoon, and the sea becomes much clearer than it is from beach level. The area around Su Portu, near the tower, is part of the same stretch of coastline worth exploring while you’re up here.
Where to Stay
Chia does have real accommodation options, including major coastal resorts alongside smaller hotels and holiday rentals — this isn’t an undeveloped area without infrastructure. What sets it apart from Villasimius isn’t a lack of places to stay, but the absence of a comparably lively, walkable town center to return to in the evening. If you’re staying in Chia, expect your accommodation itself — rather than a nearby town — to be the center of your evening, whether that’s a resort with its own restaurants or a rental where you’re driving out for dinner.

Considering an Overnight Stay in Chia?
Staying near Chia gives you more time to explore several beaches without fitting the entire coastline into a single day from Cagliari. Because Chia is spread out rather than centered around a conventional town, check each property’s exact location as well as its facilities when comparing accommodation.
Getting There from Cagliari
By car, Chia is roughly 45 minutes to an hour from Cagliari, depending on traffic and your exact starting point. Public transport does connect the two — ARST’s Line 129 has served the Cagliari–Chia route — but exact schedules and frequency can change, so check the current official ARST timetable before relying on it rather than assuming a fixed service pattern. As with Villasimius, a car makes it meaningfully easier to visit multiple beaches in one day rather than staying near a single stop.
Prefer to Visit Chia Without a Car?
If you’re staying in Cagliari and don’t want to organize buses or drive yourself, a full-day beach excursion is another way to reach the area. This experience combines time at Chia with nearby Tuerredda and includes transportation from Cagliari. Check the current itinerary and beach-access arrangements before booking.
Who Chia Is Best For
Travelers who want scenery beyond the beach itself will find the dune landscape and lagoon genuinely add something Villasimius and the beaches nearer Cagliari don’t offer in the same way. Couples and travelers seeking quiet will likely appreciate Chia’s lower-key, less town-centered character. Families can find good beach options here, though — as with any coastal area — it’s worth checking conditions on the day rather than assuming calm water everywhere. Visitors without a car can make Chia work with the ARST connection, but should expect more planning around bus timing than a spontaneous multi-beach day would allow.
Day Trip or Overnight Stay?
Day trip works well if: you’re based in Cagliari with a car and want to see Sa Colonia or Su Giudeu without changing accommodation. Pairing Chia with nearby Tuerredda makes for a full, satisfying day out west.
Staying overnight makes more sense if: you want to properly explore several of Chia’s beaches, spend real time around the lagoon watching for flamingos, or simply prefer a quieter base than Cagliari or Villasimius for part of your trip. Because Chia is more spread out than a conventional town, a night or two lets you actually settle into the area rather than rushing between stops.
Practical Tips
- Use marked paths and boardwalks through the dunes, and never walk directly over them — the dune system is fragile and actively protected, and informal shortcuts contribute to erosion
- July and August bring the heaviest crowds and the busiest parking areas at Sa Colonia and Su Giudeu specifically; late spring or September offers a quieter version of the same beaches, though conditions vary by season
- Keep more than one payment method available and confirm parking procedures when you arrive, since arrangements can vary by beach and season
- If public transport is part of your plan, verify current ARST Line 129 timings before you travel rather than assuming a fixed schedule
