The wild horses of the Giara

A basalt plateau where the ponies never left

The Marmilla and Giara region, an hour’s drive north of Cagliari, doesn’t look like the rest of Sardinia’s postcard interior — no dramatic peaks, no gorges, just a flat volcanic tableland rising abruptly out of gentle farmland near Barumini. That tableland, the Giara di Gesturi, is a basalt plateau roughly 45km² in size, capped by a layer of hard lava that resisted the erosion carving up the valleys around it, and it is the only place on Earth where the cavallini della Giara live wild.

These are small horses, standing around 120-135cm at the shoulder — properly classed as a pony by height, though islanders call them cavallini rather than pony — dark bay or black, sturdy-legged, and adapted over centuries of isolation to the plateau’s thin cork-oak forest and seasonal grazing. Genetic studies point to ancient origins, though the exact how and when they arrived on the Giara remains disputed rather than settled fact. What isn’t disputed is that they’ve been protected since 1971, after numbers dropped low enough that extinction on the plateau was a real risk, and today the population sits at roughly 500 to 600 animals living entirely without human feeding or shelter.

The paulis: why spring changes everything

The Giara’s defining feature, beyond the horses themselves, is a scatter of shallow seasonal wetlands called paulis — natural depressions in the basalt that fill with winter and spring rainfall and dry out almost completely by midsummer. These pools support their own small ecosystem, including plants found in few other places on the island, and they’re where the horses gather to drink and graze on the surrounding grass once it greens up.

Visit between March and May and there’s a real chance of seeing the pools at their fullest, foals from the current year still close to their mothers, and the plateau’s cork forest at its greenest. By August the paulis have mostly dried to cracked mud or vanished entirely, and the horses range further to find grazing, which makes sightings less concentrated even though the animals are still present year-round. Neither season is a bad time to visit — the plateau in high summer has its own stark, sun-bleached character — but spring is genuinely the better bet if seeing horses at a pool, rather than scattered and distant, matters to you.

Guided tours: 4x4, horseback context, or on foot

The Giara has several marked entrances, and while independent walking is allowed on the main trails, a local guide dramatically improves the odds of a close sighting, since guides track which parts of the plateau the herds are using week to week — information that changes with rainfall and grazing, not something a map alone tells you.

The Su Nuraxi Barumini and Giara horses four-hour tour is the most complete single option, pairing the plateau with Sardinia’s best-known nuraghe in one guided half-day. For a shorter focus purely on the plateau and its wine-producing surroundings, the Nuraghe Barumini and Giara Park tour with wine tasting adds a tasting of the Marmilla’s lesser-known reds and whites once the walking portion is done.

Travellers approaching from the Genoni side of the plateau — a quieter entrance than the Barumini approach — have the Genoni museum and Giara combined ticket, which pairs archaeological exhibits on the plateau’s early inhabitants with entry to the natural area itself.

The genetics and origin debate

Where the cavallini della Giara actually came from remains a genuinely open question among researchers, with theories ranging from ancient Phoenician or Greek trading-era introductions to a population that arrived far earlier and adapted in isolation over a much longer timescale. Genetic studies have found the breed distinct enough from mainland Italian and broader European horse populations to support conservation as a separate genetic resource, regardless of which origin theory eventually wins out.

What’s not disputed is the isolation itself: centuries on a plateau that private vehicles still can’t drive onto today, cut off from interbreeding with domestic stock, is the single biggest reason the breed has stayed as distinct as it has, in a way that populations on the more accessible Sardinian mainland haven’t.

A day in the life of a Giara herd

Herds on the Giara typically organise around a dominant stallion, several mares, and their foals, moving as a loose family group across the plateau’s cork oak woodland and open scrub rather than as one large, unified population. Grazing dominates the daylight hours, shifting toward the paulis in the cooler morning and evening when both water and the best grass are within easy reach, and retreating into whatever shade the cork oaks offer during the hottest part of a summer day.

Foals are born mostly in spring, timed to the same seasonal abundance that fills the paulis, and stay close to their mothers for the first several months — one of the reasons spring sightings often include visibly younger, smaller animals alongside the adults, distinct from the more scattered, adult-only groups typical of a late-summer visit.

Choosing your Giara visit

Approach	Best for	Trade-off
Independent walk from an access village	Budget, flexibility, own pace	Lower odds of a close sighting without local knowledge
Guided walking tour	Better sighting odds, context on the ecology	Fixed schedule, group pace
Guided 4x4 excursion	Covers more ground, less walking	Less immersive than being on foot
Combined tour with Su Nuraxi	Efficient use of a single day trip	Less time on the plateau itself

None of these is the wrong choice — it depends on whether the horses or the archaeology is the priority for the day, and how much walking you want to do in the sun.

Photographing the horses responsibly

A long lens does more work here than getting physically closer, and it should — approaching a wild herd for a better photo stresses the animals and, over a season of repeated visitors doing the same thing, can measurably change their behaviour around people. Early morning and late afternoon light, when the plateau’s flat basalt surface stops throwing back the harsh midday glare, also happens to be when the horses are most active near the paulis, so the best photography conditions and the best sighting odds line up naturally without needing to close the distance.

Keep to marked trails rather than cutting across open ground toward a distant herd, both for the animals’ sake and because the basalt surface off-trail is considerably harder walking than it looks.

The plateau’s other native life

The paulis themselves support a scatter of specialist plants that exist in few other places on the island, adapted to a cycle of being fully submerged in winter and completely dry by midsummer, and the pools attract a modest range of birdlife alongside the horses — waders and the occasional heron working the shallows while water remains. Wild boar cross the plateau’s woodland edges, more often heard crashing through cork oak scrub than seen directly, and in spring the open grassland carries a good showing of wildflowers that add colour to what can look like a stark, sun-bleached landscape for much of the summer.

None of this is the reason to visit, but it rounds out a walk across the plateau beyond the horses alone.

Parking and access at each entrance

Parking is informal and free at all four access villages — Tuili, Genoni, Gesturi and Setzu — generally a gravel area near the trailhead rather than a marked car park, and space is rarely an issue outside spring weekends when demand from both tourists and day-tripping Sardinian families peaks together. Tuili’s entrance sees the most casual foot traffic given its proximity to Barumini; Genoni’s approach, paired with its small museum, tends to draw a steadier but smaller stream of visitors across the day.

Su Nuraxi: the reason most people are already in the area

The Giara sits close enough to Su Nuraxi di Barumini — Sardinia’s only UNESCO World Heritage-listed nuraghe, a fortified Bronze Age complex with a central tower and surrounding village that’s among the best-preserved of the island’s roughly 7,000 nuraghi — that almost every operator combines the two in a single itinerary, and there’s little reason not to follow that pattern. The Su Nuraxi di Barumini UNESCO site guided tour covers the archaeological side thoroughly and typically runs a couple of hours, leaving the rest of a half or full day free for the plateau itself.

For visitors basing themselves in Cagliari without a rental car, the guided tour to Barumini and Su Nuraxi from Cagliari handles transport as well as the site visit, a straightforward option since public transport to Barumini from the coast is infrequent and slow.

On the drive back into Cagliari, several operators also run the EcoSafari flamingos tour at Molentargius, worth considering as an add-on if wildlife is the theme of your day and you’re passing back through the city before evening — see our flamingos at Molentargius guide for what that visit involves.

What the walk itself involves

The main marked trails on the Giara are flat by Sardinian standards — this is a plateau, not a mountain hike — but exposed, with little shade across most of the route and ground that turns to soft mud around the paulis after rain. A guided walking loop typically covers 4 to 6km over two to three hours, enough to reach at least one or two of the larger pools without needing serious fitness. Sturdy shoes matter more than distance here; the basalt surface is uneven and can be slippery near the wetlands.

Combining the Giara with the rest of the interior

The Giara sits within reach of several other inland highlights. Our nuraghi of Sardinia guide places Su Nuraxi in the context of the island’s wider Bronze Age archaeology, while a nuragic route across Sardinia builds a multi-site itinerary around it.

For other wildlife on the island, see national parks of Sardinia and Sardinian wildlife: what you can see, which cover the Giara horses alongside Asinara’s white donkeys and the Molentargius flamingos. If you’re driving in from Cagliari, our driving in Sardinia and renting a car in Sardinia guides cover the practicalities — there is no direct public transport route that makes a day trip here easy without a car or a booked tour.

Frequently asked questions about the Giara horses

Are the Giara horses truly wild, or semi-domesticated?

They live entirely wild, without human feeding, shelter or veterinary intervention, grazing freely across the plateau. They’ve been legally protected since 1971 but are not managed as livestock.

When is the best time to see the horses at the water pools?

March to May, when the seasonal paulis are at their fullest after winter rain and grass growth is at its peak, giving the strongest chance of seeing horses gathered near water.

Can you visit the Giara without a guide?

Yes, on the marked public trails, but a guide significantly improves your odds of a close sighting since herd locations shift with grazing and rainfall from week to week.

How far is the Giara from Cagliari, and can it be a day trip?

Around 50km, about an hour’s drive. It comfortably combines with Su Nuraxi di Barumini as a half or full day trip from Cagliari, either self-driven or on a guided tour that includes transport.

Is the Giara suitable for children?

Yes — the walking trails are flat and not technically demanding, though there’s little shade, so timing a visit for morning or late afternoon in summer is worth planning around.

Do the horses pose any danger to visitors?

No, provided visitors keep a respectful distance and don’t attempt to approach or feed them, which is both discouraged and, in the case of feeding, harmful to a population that survives on natural grazing.

Where did the Giara horses originally come from?

It’s genuinely disputed among researchers, with theories ranging from an ancient introduction during Phoenician or Greek trading contact to a much earlier arrival. Genetic studies confirm the breed is distinct, whatever the exact origin turns out to be.

Is it safe to photograph the horses up close?

Keep a respectful distance and use a longer lens rather than approaching — getting close stresses a wild herd and can alter their natural behaviour around visitors over time.
