Isola di San Pietro: A Travel Guide to a Hidden Gem in a Sea of Blue

Secluded in a sea reflecting a million shades of blue, the tiny Isola di San Pietro is one of the most beautiful and unique places to visit in the island region of Sardinia. Transparent waters, sandy beaches, scenic rock formations, and picture-perfect rocky coves line the shores of this stunning vacation retreat that lies seven kilometers off of the southwestern coast of Sardinia

Accessible by ferry, the island of volcanic origin is part of the Sulcis Archipelago. From its idyllic beaches to its hilly interior dotted with typical Mediterranean shrubberies like myrtle and rosemary and forests of pine and Aleppo, Isola di San Pietro is a paradise for travelers looking to surround themselves with uncontaminated nature in a beautiful oasis far from the cares of daily living.

The island’s main town, Carloforte, is a small enchanting center lined with pretty façades in pastel shades, a charming port, narrow streets, cobblestone stairways, and characteristic markets that create a world set apart that is home to San Pietro’s roughly 6200 year-round inhabitants.

Here the warm Mediterranean sun rises in the morning to caress the breathtaking beauty of this Italian pearl illuminating the sparkling seas until it dips down into one of the most stunning sunsets imaginable leaving an evening sky of sparkling stars and sea breezes enveloped by notes of jasmine, lily, and orange.

History & Curiosities of Isola di San Pietro

Legend has it that the island gained its name from the apostle Peter who is said to have stopped at this exact place in the year 46 AD to take shelter from a raging storm. Archeological remains found around the isle attest to a small population that had been living here since the times of the Phoenicians starting around the 8th century BC.

The island was further settled by a group of coral fishermen and their families, originally of Ligurian descent, who had been working the coral reefs off of the island of Tabarka in Tunisia for about 200 years. Having exhausted the sea beds of Tabarka, the group found fertile coral beds around Isola di San Pietro and petitioned the king of Sardinia and Piemonte, Charles Emmanuel III, for permission to settle there – thus establishing the town of Carloforte (Charles the strong) in his honor.

Locally known as U Pàize, Carloforte still exhibits a strong connection with its Ligurian heritage in its architecture, foods, dialect, and culture. 

Do & Experience

Isola di San Pietro is known for its dreamy beaches, slow-paced living, pure nature, and plentiful watersports. Days on the island can be spent swimming in the refreshing waters, laying on its warm sands, hiking its many trails, or diving into its crystal sea.

Sea and Sun

Exploring the location’s beautiful coastline is a must. Start with the beach known as Giunco – the longest on the island with its serene shallow waters. Continue to Girin and Punta Nera – known for their clear, calm shores and Mediterranean vegetation protected from the mistral winds. La Bobba is surrounded by the jagged edges of rocky cliffs, secluding it from the world around and offering views of the columns of rock emerging from the sea. From there, head to La Caletta – one of the island’s most renowned beaches accessible via a short trail; or go on to the lighthouse of Capo Sandalo and the beach of Cala Fico – a tiny oasis covered with large pebbles that has incredibly transparent waters.

Otherwise, visit one of the island’s most unique swimming spots, Piscine di Nasca – a series of naturally formed pools carved into the volcanic rock by the sea’s winds that fill with water from the sea creating nature’s very own swimming pools. 

Diving and snorkeling are also magnificent activities. Enjoy some of the best diving tours in all of Sardinia, complete with views of the area’s marine life, stony coral, shipwrecks, and Roman ruins, as well as stops for swimming and exploring hidden caves. Look to Isla Diving and Carloforte Diving for information and organization. Courses are available.

Then, at the end of the day, linger at the lighthouse of Capo Sandalo for breathtaking sunsets that swirl from yellow to orange to pink.

Immerse Yourself in Nature

San Pietro is known for the many species of birds that arrive on the island throughout the year. A trip to the Salt Pans of Carloforte is an ideal place to explore the land, its history, and watch the birds and fauna that call the area home.

At the LIPU reserve on the island’s west side, you can catch a glimpse of a colony of falcons known as Eleonora’s falcons – so named for Eleanora of Arborea who as ruler of the area in 1392 became the first official to grant legal protection to the falcons and hawks who made their nests on the island but were often killed by local hunters. Today the reserve offers amazing sights of these great birds as they soar overhead. The best times to see them are from July to October.

Hikers will also be pleased to discover that the island has numerous trails from its sun-drenched interiors to its sea-lined shores. For amazing views of the sea and sky and striking vegetation, hike along the paths at the oasis near Cala Fico on the northern coast.

Discover Carloforte

The island’s center of Carloforte itself is well-worth some time exploring. This unique location is a resort town with a fishing soul. Colorful buildings and pretty views make it the perfect spot for taking photos. Wander the charming central square, Piazza Pegli, listening to locals speaking in their traditional dialect known as Tabarkine.

Make your way to the western side of the town to discover the remains of defensive walls built in 1806 after an invasion by Tunisian corsairs who captured and enslaved many of the island’s inhabitants. Explore the three forts of Saints Cristina, Teresa, and Beatrice or enter Carloforte’s castle constructed in 1738 to house soldiers. One of the most photographed spots in town is the arch that dates back to the end of the 18th century known as Archiottu – originally the entrance to the lush gardens of one of the island’s most prominent families.

More time in town can be spent exploring the Multimedia Museum of the Sea, visiting the town’s two beautiful churches, shopping at the tiny stores, or sitting at a café to enjoy a moment’s pause, breathing in the deep sense of peace that permeates the air.

From here, you can also find jeep tours of the island, boat rentals, diving centers, ferries, or excursions to the old tuna fishing station.

Take a day trip to Calasetta and Sant’Antioco

Catch a 30-minute ferry to the other principal island of the Archipelago of Sulcis, Sant’Antioco. Take the time to see the town of Calasetta, view an ancient acropolis, an antique Roman bridge, or the Paleo-Christian basilica with its catacombs. The island’s coast is partly sandy and partly rocky with splendid beaches such as those of Maladroxia, Coaquaddus, Sotto Torre, Le Saline, and Spiaggia Grande.

Foods to Try

The traditional tastes of Isola di San Pietro are a mélange of perfumes and flavors that are a testament to its history, blending the simplicity of fresh seafood with touches of Ligurian and Arab cuisine.

Locally caught tuna and fish dominate menus with fresh simple ingredients. Local creations include tuna served with tomatoes, white wine, bay leaves, and extra virgin olive oil, or the lasagna with tuna and pesto, and the traditional Cassolla fish soup.

Handmade pasta is also an important part of the local cuisine. Try the Raiélu, a ravioli with beets and ricotta, or the Macariun or Curzetti served with fresh fragrant basil pesto. Other hints of Liguria as well with typical Ligurian focaccia and farinata di ceci – made with chickpea flour.
