We spent over two months on Sant’Antioco and during that time we crisscrossed it from end to end. It’s an island full of surprises – wild, untouched beaches with wonderfully emerald-turquoise waters, cycling trails with sea views, diving and snorkeling in the crystal-clear Mediterranean, and on top of that, a fascinating history dating back to Phoenician times. Sant’Antioco is the perfect holiday destination for outdoor-loving families who want to experience more than just lying on the beach. Unlike northern Sardinia, here you can truly relax without the crowds.

The history of Sant’Antioco – an open-air museum older than Rome
Before I tell you why Sant’Antioco so completely charmed us – outdoor-loving, active parents – I absolutely have to share at least a little bit about the incredible history of this tiny island, set just off the southwestern tip of Sardinia.
The history of this little island goes all the way back to the 8th century BC. That’s when the Phoenicians founded a settlement here called Sulci, which quickly became one of the most important trading hubs in the entire Mediterranean. From here, ships set sail carrying the most valuable goods of Antiquity, such as purple dye (an extremely costly royal pigment extracted from sea snails), wine, and olive oil, while merchants brought goods in from Africa and the Iberian Peninsula.
What’s really fascinating is that Sulci was thriving long before Rome even existed! As you might recall, the Eternal City was founded in 753 BC, while the settlement on Sant’Antioco appeared several decades earlier. The Phoenicians left behind monumental necropolises and catacombs, which can still be admired today – especially in the Archaeological Museum (which we highly recommend visiting).
Later the island came under the control of the Carthaginians and then the Romans, who expanded Sulci and turned it into a strategic military and trading base. In Roman times the city was bustling – temples, a forum, and aqueducts were built. You can still find remnants of these buildings in the town of Sant’Antioco, along with fragments of early Christian basilicas and catacombs that show the island remained an important religious center in later centuries as well.
It’s quite extraordinary – as you walk through today’s town, or drive across the causeway built by the Phoenicians that still connects Sant’Antioco with Sardinia, you realize that beneath your feet (or wheels) lie nearly three thousand years of history. Sant’Antioco is truly an open-air museum!
We were deeply impressed.
LLife in the Tuff Caves – A Unique 20th-Century Story
Sant’Antioco isn’t only about the ancient history of the Phoenicians and Romans – it also holds some unusual stories from much more recent times. As late as the 1950s and 60s, some island residents lived in caves carved into soft volcanic tuff (a type of rock formed by volcanic eruptions, easy to shape and work with). These natural shelters, partly expanded by humans, were found on the town’s outskirts.
The people who lived in these caves were disparagingly called “is gruttaius” (from grutta – cave), which in the local dialect was close in meaning to “hole people” or “cave dwellers.” Although they lived modestly, the caves protected them from heat and cold, were easy to maintain, and cheap to use.
In the 1960s, the authorities began moving families from the caves into new social housing. Some caves, however, were preserved, and today you can still see them as a reminder of this remarkable chapter in local history. Walking through Sant’Antioco’s streets, it’s hard to believe that only a few decades ago people here truly lived as if time had stood still for centuries.
Amazing, isn’t it? And most importantly – if you’re traveling with children, visiting such places is a fantastic lesson in history and culture. Kids can see with their own eyes how real people once lived in their natural environment.
Museo del Bisso – Discover the Magic of Sea Silk on Sant’Antioco
If you’re on Sant’Antioco and enjoy discovering local culture, especially when it connects directly to nature and outdoor life, then we highly recommend visiting a completely unique place.
In the heart of Sant’Antioco’s Old Town, you’ll find the extraordinary Museo del Bisso, run by Chiara Vigo – one of the last masters in the world of the art of weaving with byssus, also known as sea silk. This rare, lighter-than-a-feather (seriously!), almost mythical material is made from fibers produced by Pinna nobilis mussels, which once thrived in the Mediterranean. After careful treatment, byssus gains a golden sheen and exceptional durability – in the past it was considered a royal fabric, adorning the garments of priests and monarchs. Today it is priceless intangible heritage.
A visit to the museum doesn’t feel like a regular tour – it’s more of an intimate encounter with tradition, history, and spirituality. Chiara Vigo talks about her work, shows samples of byssus and the process of preparing it (while singing traditional songs), and shares stories about the meaning of this craft in Mediterranean culture.
Even though the whole meeting was in Italian – and we mostly relied on context (we know a bit of Spanish, and I know some French) – it was still a profoundly moving experience. To meet someone who has dedicated her life to preserving a unique tradition passed down from generation to generation along the female line of her family is something unforgettable. Museo del Bisso is one of those places on Sant’Antioco that stays with you for a long time – not just as a tourist attraction, but as an encounter with something truly unique and timeless (I still get chills when I think of meeting Chiara. Honestly.)
Okay, we’ve covered the historical gems. Now it’s time for outdoor wonders!
Cycling in Sant’Antioco – Scenic Trails and Hidden Coves
The island is a paradise for cyclists – you’ll find asphalt roads running along lagoons and the coast with breathtaking sunset views, as well as more demanding off-road trails winding through maquis-covered hills. Exploring by bike lets you reach wild coves and viewpoints where you can watch flamingos wading in the water (and to think we saw them every morning right outside our campervan window!), breathe in the scent of Mediterranean herbs, admire fishing boats rocking on the waves and… well, you’ll fall in love with these landscapes just like we did!
If you’re into cycling, check out our separate post: Cycling Island Sant’Antioco – where we describe our favorite trails for both kids and adults.
Diving and snorkeling – octopuses and rocky corridors in crystal-clear waters
Sant’Antioco is one of the best places for snorkeling and diving in southern Sardinia. The vizura – that’s diver-speak for underwater visibility – is phenomenal. Nowhere else in the world have we seen water this clear. Beneath the surface you’ll discover volcanic rock formations, caves, corridors, and grottos (our favorites are Pan di Zucchero and Grotta Azzurra), some of which you can even surface inside (an incredible experience!). You’ll encounter barracudas, lobsters, octopuses, rays – and even dive near shipwrecks.
Who to dive with on Sant’Antioco?
If you’re heading to Sardinia or Sant’Antioco, definitely get in touch with Dominika and Piotr from Sirena Sardinia – a Polish diving school on the island. We dove with them all summer long. Not only do they have the best equipment on the market and a wealth of knowledge (Piotr is a technical and cave diving instructor), but they’re also simply warm, welcoming people. They’ll dive with you (or teach you how), and share insider tips about the whole region. And since they’re parents and outdoor lovers too, you’ll get all the best secret recommendations for places and adventures.
Windsurfing and kitesurfing in Porto Botte
Here’s another heartfelt recommendation. Just a 20-minute drive from Sant’Antioco you’ll find an ideal spot for flying across the water’s surface. Porto Botte, as it’s called, is a mecca for kitesurfers from all over Europe – steady winds, shallow water, and the fantastic Sky High base (run by Polish couple: world windsurfing champion Marta Hlavaty-Orłowska and Karol Orłowski “Orzeł”). Here you can rent all the gear, book lessons, or even join a full kitesurfing or windsurfing camp – just like our kids did.
Best Beaches in Sant’Antioco – Our Family-Friendly Picks
Even though we’re not really the “lie on the beach” type, we know kids need that time for free play in the water or sand (our rule: one intense day, one chill day). We usually look for uncrowded beaches where dogs are allowed (a true rarity in Italy and Sardinia – and even then, usually only in the evenings). So we put together a list of our favorite beaches for you.
A quick note: on Sant’Antioco you’ll find turquoise, crystal-clear water everywhere. Each beach has its own charm – some have more rocks (perfect for kids to explore), others have natural rock pools for jumping in, and still others offer wide stretches of soft sand. There’s something for everyone.
- Maladroxia – light sand, turquoise water, beach bars, umbrellas, sunbeds… but also the biggest crowds in high season.
- Arco dei Baci – a magical place! A natural rock pool where you can swim if the sea is calm (sometimes waves are so strong you can’t even get down safely). No sand here – you sit on rocks under the cliffs.
- Cala Sapone – a fairly wide beach with nice sand, fun flat rocks to scramble over, and across the road a tavern serving tasty food (try the Sardinian dumplings culurgiones).
- Cala Lunga – a small hidden cove, perfect for a family picnic. There’s also a simple beach bar.
- Coaquaddus – a wide sandy beach with a gentle slope into the water, plus a charming beach restaurant right by the shore.
Trekking and cliff walks
Hiking trails lead across cliffs and hills with sweeping views of Isola di San Pietro and the open Mediterranean. Even in peak tourist season you can find peaceful walks here.
We especially recommend the cliff path to Capo Sperone – the island’s southernmost point, with dramatic rocky cliffs and often birds of prey soaring overhead. The trail winds through maquis-covered hills filled with aromatic herbs and wildflowers.
Another favorite was the walk along the cliffs between Arco dei Baci and the Bronze Age monument Tomba dei Giganti (Su Niu ’e su Crobu). You can park at the grove by Carolina Ranch and from there simply wander – on foot or by bike – around the area. The views are stunning, and the sunsets unforgettable.
Nature – flamingos and lagoonsFlamingos and Lagoons – The Wild Nature of Sant’AntiocoNature – flamingos and lagoons
Sant’Antioco’s salt flats (saline) have been used for centuries to harvest sea salt. Today they’re one of the island’s most iconic landscapes – wide, flat sheets of water shimmering in shades of pink, violet, blue, and green depending on the light and season. These shallow basins are where flamingos nest, along with other water birds like herons and terns.
We were so lucky to watch these incredible birds almost every day from our camper windows – they came right up close when we camped by the salt flats in Porto Botte. And that moment when flamingos take flight and soar just overhead… priceless!
Sant’Antioco – where to sleep and where to eat?
Okay, once you arrive on this small outdoor Sardinian island, you’ll need somewhere to sleep, right? For us that wasn’t an issue since we travel in our home-on-wheels. But I assume 99% of you would like some recommendations.
During our van adventures around Sant’Antioco and Sardinia, we were lucky to meet wonderful people who showed us the island from a totally non-touristy side, making us feel like locals. Thanks to a tip from Dominika of Sirena, we decided to spend our last three nights in a Sardinian apartment in the very heart of Sant’Antioco’s Old Town. And it was the best decision! Not only was it a surprise for the kids (air-conditioning after three months of summer heat in the van – you get it, right?), but it also gave us a break from managing everything ourselves.
Our little flat in a Sardinian townhouse is listed on Tutto Sant’Antioco, which has over 200 apartments and houses for rent across the island. If you’re planning to come in summer (high season), it’s worth booking in early spring. But we recommend visiting in September–October or April–May – you’ll have the place practically to yourselves :).
