Introduction

Alghero was the first city I saw when I arrived in Sardinia back in 2009, and I fell in love instantly. I still remember the feeling of wonder I experienced walking along the bastions at sunset for the first time, as the sun painted the ancient Catalan walls red and the sea stretched endlessly before my eyes. It was in that moment I knew the island would forever have a special place in my heart.

Nestled on the northwestern coast of Sardinia, Alghero is one of the island’s true gems—a city that enchants visitors with its unique charm, blending Italian and Catalan cultures. Nicknamed “Barceloneta” (little Barcelona), this fascinating city boasts a historical, cultural, and natural heritage of extraordinary value, making it a must-see destination in Sardinia.

Among the many highlights of Alghero are its Catalan-style old town, surrounded by imposing sea-facing bastions, the spectacular Neptune Caves at the foot of the Capo Caccia cliffs, and the stunning beaches of the Coral Riviera. But Alghero is much more than that: it’s a vibrant city with deep-rooted traditions, a cuisine that blends the flavors of land and sea, and a welcoming atmosphere that makes every visitor feel right at home.

In this article, I’ll guide you through the best things to see in Alghero—from historical monuments to natural wonders—along with suggestions for activities to truly experience this extraordinary Sardinian city. Whether you’re passionate about history, a nature lover, a foodie seeking authentic flavors, or simply looking for a relaxing beach holiday, Alghero will win you over with its timeless charm.

History of Alghero

Alghero’s history is both fascinating and complex, deeply intertwined with Mediterranean events and the various powers that ruled Sardinia through the centuries.

The first settlements in the area date back to the Nuragic era, as evidenced by the many nuraghes found near the city. However, the true founding of Alghero is attributed to the Genoese Doria family, who in the 12th century established a commercial and military outpost here, naming it “Aleguerium” (from the algae that grew abundantly along the coast).

The turning point in Alghero’s history came in 1354, when the city was conquered by the Crown of Aragon. King Peter IV of Aragon repopulated the city with Catalan settlers after expelling most of the local inhabitants. This event deeply shaped Alghero’s identity, turning it into a truly Catalan city in Sardinia—so much so that it earned the nickname “Barceloneta.”

During the four centuries of Aragonese and later Spanish rule, Alghero flourished as an important commercial port and coral fishing hub. It developed a distinctive culture and language (Algherese Catalan, still spoken today) that set it apart from the rest of the island. The mighty fortifications that still define the historic center date from this era.

After the War of the Spanish Succession, Sardinia was handed over to the Habsburgs in 1714 and then to the Savoy dynasty in 1720. Despite these political changes, Alghero preserved its Catalan soul, which remains a defining feature of its character today.

In the 20th century, with the rise of tourism, Alghero became one of the most popular destinations in Sardinia, successfully combining its rich historical and cultural heritage with the natural beauty that surrounds it.

Today, strolling through Alghero’s old town, you can still feel the presence of its layered past—reflected in its architecture, language, traditions, and local cuisine.

The Historic Center

The beating heart of Alghero is its charming historic center, a maze of cobblestone streets, picturesque little squares, and ancient buildings that tell stories of centuries past. Surrounded by the imposing Aragonese walls, Alghero’s historic center is an open-air museum, one of the most distinctive places in all of Sardinia and certainly one of the top things to see in Alghero.

The Walls and Bastions

The walls and bastions surrounding the historic center are among the main sights in Alghero. Built starting in the 13th century and later expanded and reinforced during the Aragonese rule, these impressive defensive systems are one of the best examples of medieval military architecture in Sardinia.

Today, visitors can walk along much of the walls and enjoy a stunning view of the crystal-clear sea. Particularly scenic spots include the Cristoforo Colombo Bastion, the Maddalena Bastion, and the Marco Polo Bastion, from which you can admire a spectacular sunset over Alghero Bay. Along the route, you’ll also find several watchtowers, such as the Tower of San Giovanni and the Tower of Sulis, which highlight Alghero’s strategic importance in the past.

A walk along the bastions at sunset is one of the most pleasant and romantic things to do in Alghero, offering a chance to fully appreciate the beauty of Sardinia’s own "Barceloneta".

The Cathedral of Santa Maria

In the heart of the old town stands the Cathedral of Santa Maria, one of the main religious monuments in Alghero and a must-see for anyone exploring the city. Built between the 16th and 17th centuries in late Catalan Gothic style with Renaissance elements, the cathedral features a neoclassical façade added in the 18th century.

Inside, the three-aisled structure houses numerous artistic treasures, including a fine 16th-century wooden crucifix, a multicolored marble baptistery, and richly decorated chapels. Particularly noteworthy is the Chapel of the Blessed Sacrament, with its elaborate Baroque decorations.

The octagonal bell tower, standing 42 meters tall, is one of Alghero’s skyline icons and offers a panoramic view of the city and sea to those willing to climb its 200 steps.

The Church of San Francesco

Another important testament to Alghero’s Catalan past is the Church of San Francesco, located in the square of the same name in the historic center. Built in the 14th century by Franciscan friars, the church has undergone various renovations over the centuries but still preserves its magnificent Gothic cloister, one of the best preserved in Sardinia.

Inside the church, you’ll find a beautiful polychrome marble main altar, richly decorated side chapels, and several interesting works of sacred art. The cloister, with its elegant columns and finely carved capitals, is a peaceful oasis in the heart of the city and often hosts concerts and cultural events during the summer.

The Church of San Michele

While walking through Alghero’s historic center, it's impossible to miss the colorful dome of the Church of San Michele—one of the city's most recognizable landmarks and one of the top sights to see in Alghero.

Built by the Jesuits between the 17th and 18th centuries, the Church of San Michele is a beautiful example of Baroque architecture in Sardinia. Its relatively simple façade contrasts with the richness of the interior, but it’s the dome that immediately catches the eye: covered in multicolored majolica tiles in shades of yellow, green, and blue, it sparkles under the Mediterranean sun and stands out against the sky in one of the most photographed cityscapes in Alghero.

The single-nave interior with side chapels hosts several fine artworks, including a polychrome marble main altar and Baroque paintings. Particularly impressive is the finely carved wooden pulpit, a masterpiece of local craftsmanship that showcases the skill of Sardinian woodworkers.

The church is located on Via Carlo Alberto, one of the main streets in the old town, and is easily reachable on foot during a walk through the alleys of the “Barceloneta.” The building is open to visitors during designated hours, and if you're lucky enough to visit during a religious service, you’ll also appreciate the church’s excellent acoustics.

The dome of San Michele is especially beautiful at sunset, when the last rays of sunlight enhance its vivid colors. It also serves as a valuable landmark for navigating the maze of streets in the historic center. Tourists and locals alike often stop to admire it, looking up at this architectural gem that blends Spanish, Italian, and local influences—perfectly reflecting Alghero’s complex cultural identity.

Palazzo d’Albis and Other Historic Buildings

As you stroll through the streets of Alghero’s old town, you'll notice numerous noble palaces that reflect the city’s prestige during Spanish rule. Among them, Palazzo d’Albis stands out with its elegant Gothic-Catalan façade and twin-arched windows.

Other historic landmarks include the Tower of Esperó Reial, also known as the Tower of Porta Terra, which once served as the main entrance to the fortified city, and the Civic Theatre, built in the 19th century and recently restored.

The historic center also hosts several interesting museums, such as the Coral Museum, which tells the story and techniques of working with this precious material—so important to Alghero’s economy and culture—and the City’s Archaeological Museum, which displays artifacts from prehistory to the modern era, offering an insightful overview of Alghero’s history and surroundings.

The Coral Riviera

Alghero is also known as the capital of the "Coral Riviera," a coastal stretch that extends for about 90 km from the city to Stintino. It is characterized by crystal-clear waters, fine sandy beaches, and dramatic sea cliffs. The name comes from a precious variety of red coral that grows on the seabed in this area, which for centuries has been a vital economic resource for the city.

The tradition of coral fishing and craftsmanship is a fundamental part of Alghero’s cultural identity. Since medieval times, Alghero’s coral fishermen have been renowned for their skill in harvesting and crafting this precious material into jewelry and decorative items admired across Europe.

Today, although coral fishing is strictly regulated for environmental conservation, Alghero still keeps this tradition alive through skilled artisans who continue to create beautiful coral jewelry. In the old town, there are many specialized workshops and boutiques where you can admire and buy authentic Sardinian pieces such as necklaces, bracelets, earrings, and pendants made from red coral.

To learn more about this local tradition, visit the Coral Museum, where you can explore traditional fishing and crafting techniques, admire ancient tools and beautiful historical artifacts, and better understand the importance of the “red gold” in Alghero’s history.

Beaches Not to Miss

Among the top things to see in Alghero are its stunning beaches, offering extraordinary scenery and clear waters ideal for swimming and water sports.

The beach closest to the city center is San Giovanni, a long stretch of fine sand that runs for several kilometers, equipped with beach clubs and facilities. It’s perfect for families, thanks to its shallow waters and soft sand, and is easily reachable on foot from the old town.

Heading north, you’ll find the Lido and Maria Pia beaches, known for their white sand, dunes covered with junipers and pine trees, and waters that range from turquoise to emerald green. These beaches are especially appreciated for their natural beauty and the available amenities, including bars, restaurants, and water sports.

But the real gems of the Coral Riviera are found inside the Porto Conte Natural Park, where hidden coves of rare beauty await—like Mugoni Beach, a wide golden-sand bay sheltered from the wind, and the small but enchanting Lazzaretto Beach, nestled in a bay protected by high cliffs.

For lovers of wilder landscapes, don’t miss Cala Dragunara and Porto Agra—small, pristine coves accessible by sea or through scenic trails, where you can enjoy unspoiled nature and crystal-clear water.

Capo Caccia and Neptune’s Caves

Among the top attractions in and around Alghero, Capo Caccia and the famous Neptune’s Caves hold a place of honor—true natural wonders that leave visitors in awe.

Capo Caccia is a massive limestone promontory about 20 km from Alghero, with steep cliffs that drop dramatically into the sea, reaching heights of up to 300 meters. Its unmistakable silhouette, reminiscent of a sleeping giant, is visible from the city and is one of the most iconic landmarks of northwestern Sardinia.

At the base of this majestic headland lie Neptune’s Caves, one of the most spectacular karst cave systems in the Mediterranean, formed over millions of years by the erosive action of the sea and underground waters on the limestone rock.

How to Visit the Caves

There are two ways to visit the Neptune Caves, both fascinating and offering different but equally memorable experiences.

The first is by sea, with a boat excursion departing from the port of Alghero and skirting the spectacular cliffs of Capo Caccia, offering breathtaking views and the chance to spot various species of seabirds, including the rare Eleonora’s falcon. The crossing takes about 45 minutes and, in calm seas, allows direct entry into the cave’s mouth.

The second way is by land, descending the spectacular “Escala del Cabirol” (Roe Deer’s Stairway), a staircase carved into the rock in the 1950s that includes about 660 steps overlooking the sea. The descent requires some physical effort but rewards visitors with unforgettable views of the Porto Conte bay and the crystal-clear sea below. Keep in mind that the climb back up can be quite challenging, especially on hot days.

Once inside, the guided tour of the Neptune Caves lasts about an hour and allows visitors to admire spectacular formations of stalactites and stalagmites, alabaster columns, and the enchanting Lamarmora saltwater lake, one of the largest underground lakes in Europe. Artistic lighting enhances the natural beauty of the cave, creating an almost surreal atmosphere.

It is important to check the opening hours of the caves in advance, as they may vary depending on the season and sea conditions. Booking in advance is also recommended, especially during the summer months when there is a high influx of visitors.

The Porto Conte Natural Park

Capo Caccia is part of the Porto Conte Regional Natural Park, a protected area that includes the bay of the same name and extends over 5,000 hectares of land and sea. The park is an ecosystem of extraordinary importance, home to numerous endemic plant species and a rich fauna, including Sardinian deer, fallow deer, wild boars, and several species of birds of prey.

A visit to the park is one of the most recommended things to do in Alghero for nature lovers. Numerous trails allow you to explore on foot or by mountain bike the various environments, from coastal pine forests to Mediterranean scrubland, and wetland areas rich in birdlife.

Particularly noteworthy is the nature trail leading to the Punta Giglio viewpoint, which offers a spectacular view over the entire Porto Conte bay and Capo Caccia. For the more adventurous, there are more demanding trekking routes climbing the slopes of Mount Doglia, the highest peak in the area.

The park also houses the Environmental Education Center of Casa Gioiosa, where you can find detailed information about the trails and participate in guided tours and educational activities. For birdwatching enthusiasts, the Calich lagoon area is particularly recommended, as it is an important stopover site for migratory birds.

Alghero and Surroundings

The wonders to discover do not end with the city of Alghero and its immediate surroundings. The surrounding area offers numerous attractions of great historical, archaeological, and natural interest that are well worth a visit.

Nuraghe Palmavera

About 10 km from the center of Alghero lies the Nuraghe Palmavera, one of the most important archaeological sites in northwestern Sardinia. This Nuragic complex, dating back to the 15th century BC, is an extraordinary testimony to the Nuragic civilization that marked Sardinian prehistory.

The site includes a complex nuraghe with a central tower and a second, later-added tower, surrounded by a village of huts. Among them stands out the “meeting hut,” a large circular room likely used for community gatherings or ritual ceremonies.

A visit to the Nuraghe Palmavera offers an immersive experience into the mysterious Nuragic civilization and provides deeper insight into Sardinia’s ancient origins. The site is open year-round, with hours varying depending on the season, and offers guided tours that greatly enhance the experience.

Necropolis of Anghelu Ruju

Not far from Nuraghe Palmavera is the Necropolis of Anghelu Ruju, the largest prehistoric necropolis in Sardinia, discovered by chance in 1903 during agricultural work. The site includes about forty hypogeic tombs (domus de janas) carved into the limestone rock, used from the 4th millennium BC through the Bronze Age.

The tombs, consisting of multiple interconnected chambers, have yielded numerous artifacts, including funerary goods, pottery, jewelry, and weapons—many of which are now housed in the National Archaeological Museum in Cagliari and the Archaeological Museum of Alghero.

Visiting the necropolis offers a fascinating glimpse into the funerary practices and religious beliefs of the ancient peoples who inhabited Sardinia before the Nuragic era, making it a must-see for anyone interested in archaeology and the island’s prehistory.

Bosa and Castelsardo

Those with a bit more time should consider exploring other charming destinations not far from Alghero. Among them, Bosa and Castelsardo are certainly worth a visit.

Bosa, located about 40 km south of Alghero, is a picturesque river town known for its colorful houses climbing the hill dominated by the Malaspina Castle. Its historic center, with cobblestone streets and noble palaces, retains an authentic charm and offers truly beautiful views. Don’t miss a walk along the Temo River, the only navigable river in Sardinia, and a visit to the Church of San Pietro, a splendid example of Romanesque architecture.

Castelsardo, about 60 km northeast of Alghero, is an ancient medieval village perched on a promontory overlooking the sea, dominated by the Doria Castle. Famous for its basket weaving craftsmanship, the historic center is a maze of steep alleys and stairways leading to panoramic terraces with breathtaking views of the Gulf of Asinara. The Cathedral of Sant’Antonio Abate is a must-see, housing a fine Black Christ sculpture, an object of deep devotion.

Both locations also offer excellent gastronomic opportunities to taste typical Sardinian products in authentic and scenic settings.

Things to Do in Alghero

In addition to the many sights to see in Alghero, the city and its surroundings offer a wide range of activities and experiences that let visitors fully enjoy the beauty and culture of this corner of Sardinia.

Outdoor Activities

Alghero is a paradise for lovers of outdoor activities. Its crystal-clear waters are ideal for snorkeling and scuba diving, with many diving centers offering courses and guided excursions to discover seabeds teeming with marine life and red coral. If you want to enjoy this experience, you can book a guided diving session right here. Especially popular are the dives into the underwater caves of Capo Caccia, including the famous Nereo Cave, one of the largest submerged cavities in the Mediterranean.

For those who prefer staying on the surface, kayaking and stand-up paddleboarding (SUP) provide perfect ways to explore the coast, reach hidden coves, and enjoy unique views from the sea. Numerous operators offer equipment rentals and guided tours along the Coral Riviera.

Sailing and windsurfing enthusiasts will find ideal conditions in the Porto Conte bay, thanks to consistent winds and sheltered waters. For the more adventurous, kitesurfing is particularly popular on mistral wind days.

The inland areas of Alghero offer excellent opportunities for hiking and mountain biking, with trails of varying difficulty winding through landscapes of extraordinary beauty. The Porto Conte Natural Park has a well-marked trail network, perfect for trekking and birdwatching.

Events and Festivals

Alghero is a lively city year-round, with a calendar full of cultural, sporting, and gastronomic events that enliven its streets and squares.

One of the most eagerly awaited events is New Year’s Eve, when Alghero becomes the “New Year’s Capital of Sardinia,” featuring concerts, performances, and the traditional countdown in Piazza Civica, followed by spectacular fireworks over the bay.

During Holy Week, the city celebrates ancient religious traditions of Catalan origin, with evocative processions and rites that attract many visitors. Especially moving is the Good Friday procession, with confraternities in traditional dress parading through the old town.

Summer is the richest season for events, with music, theater, and dance festivals held in scenic open-air venues such as the city walls and old town squares. The International Fireworks Festival, usually held in August, is one of the most spectacular events, with international teams creating stunning pyrotechnic displays over the sea.

For food and wine lovers, numerous festivals and events are dedicated to Sardinian specialties, such as the Algherese Wine Exhibition and the Bogamarì Festival (sea urchin), offering opportunities to sample local delicacies in a festive, welcoming atmosphere.

How to Get There

Alghero is easily accessible from both Italy and abroad, with various transportation options.

By plane

The most convenient way to reach Alghero is by plane. The city is served by Alghero-Fertilia Airport (Aeroporto di Alghero-Fertilia), located about 10 km from the city center. The airport offers numerous connections with major Italian cities (such as Milan, Rome, Bologna, Turin, and Pisa) as well as international destinations, especially in the summer months, thanks to several low-cost airlines. From the airport, you can easily reach the city by taxi, rental car, or public bus.

By Ferry

Those who prefer to travel by sea can take advantage of the ferry connections to Sardinia. The main ports of arrival are Porto Torres (about 35 km from Alghero), Olbia and Golfo Aranci (around 130 km away), and Cagliari (approximately 225 km away).

From these ports, you can continue to Alghero by car, public transport, or private transfer services. If you choose to disembark at Porto Torres, the most convenient solution is the ARST bus, which connects the port directly with the center of Alghero.

By Car

For those already in Sardinia or who have brought their car on the ferry, Alghero is connected to the rest of the island via a good road network. The main road is the SS131 (Carlo Felice), which crosses Sardinia from north to south. From it, the SS291 branches off and leads directly to Alghero.

From Cagliari Airport, the drive takes about 2 hours and 30 minutes, while from Olbia it takes around 2 hours. The trip from Porto Torres is much shorter, about 40 minutes.

Once in the city, it's advisable to park your car in one of the parking areas located outside the historic center, which is largely pedestrianized or restricted to limited traffic, and continue on foot or by public transport.

What to Eat

Alghero’s cuisine is a fascinating blend of Sardinian culinary traditions and Catalan influences, offering visitors a unique and varied gastronomic experience. Discovering the local flavors is one of the most rewarding things to do in Alghero for every food lover.

Typical Dishes

Among the must-try local dishes are specialties based on seafood and shellfish, which are the heart of Alghero’s maritime cuisine.

Catalan-style lobster (also known as "alla algherese") is perhaps the city’s most iconic dish: boiled lobster seasoned with tomatoes, onion, celery, lemon, and olive oil. Also well-known is the “bogamarì” — sea urchin — typically eaten raw, accompanied simply with pane carasau (a traditional crispbread) and a good local white wine.

Other seafood specialties to try include “cassola,” a rich and flavorful fish soup, and “catalan,” a seafood salad seasoned with tomato, onion, and olive oil. Don’t miss the fregola ai frutti di mare — small, couscous-like pasta pearls cooked with mussels, clams, and shrimp.

But Alghero’s cuisine isn’t just about seafood. From the inland areas come hearty dishes such as favata — a rich stew of fava beans with pancetta and sausage — and cordula, braided and roasted lamb intestines. Malloreddus alla campidanese(Sardinian gnocchetti with sausage and tomato) and culurgiones (ravioli filled with potatoes, mint, and pecorino cheese) are perfect examples of Sardinian specialties that can also be enjoyed in Alghero.

As for desserts, don’t miss the seadas — fried pastries filled with fresh cheese and drizzled with honey — and bruglioni, almond sweets typical of Alghero’s Catalan tradition.

All of these dishes can be paired with the area’s excellent wines, such as Vermentino di Sardegna DOC — ideal with seafood — or Cannonau, perfect with meats and cheeses.

Recommended Restaurants

Alghero offers a wide selection of restaurants, trattorias, and eateries where you can enjoy the local cuisine, ranging from refined and elegant venues to more casual and budget-friendly options.

Many high-quality restaurants are located in the historic center, with outdoor tables in charming squares or along the old bastions, allowing guests to dine with a sea view. Prices here may be slightly higher, but the experience is definitely worth it.

For those seeking a more authentic experience and lower prices, it’s a good idea to venture away from the most touristy areas and explore the side streets, where you can find family-run trattorias serving genuine traditional dishes at reasonable prices.

For a full gastronomic experience, consider visiting one of the agriturismi in the Alghero countryside, where you can enjoy farm-style meals prepared with fresh, local ingredients — often produced directly on-site.

Finally, for a quick bite or an aperitif, the historic center is full of bars and wine bars where you can sample local cheese and cured meat platters, accompanied by a good glass of Sardinian wine.

Practical Tips for Your Visit

To make the most of your time in Alghero and discover all the best things to see, here are some practical tips that might come in handy.

The best season to visit Alghero depends on your preferences and the kind of experience you're looking for. Summer (June to September) is the most popular time, with warm temperatures ideal for enjoying the sea and beaches. However, it is also the busiest and most expensive season.

Spring (April to May) and autumn (October to November) offer mild, pleasant weather, perfect for exploring the town and its surroundings, with fewer tourists and more affordable prices. Even winter has its charm, with a quieter and more authentic city atmosphere, although some attractions and services may be closed or operate with reduced hours.

As for getting around, Alghero’s historic center is easily walkable, being a pedestrian zone. To reach nearby beaches and attractions in the surrounding area, there are urban and suburban bus services available. However, for maximum flexibility and to fully explore Alghero and its surroundings, renting a car is highly recommended — especially if you're staying more than a couple of days.

Another great option, particularly in the warmer months, is renting a bicycle. This allows you to move around easily and enjoy the scenic bike path that runs along the coast all the way to Maria Pia beach.

If you're interested in visiting the Neptune's Grotto, keep in mind that boat tours may be canceled in case of rough seas. It's a good idea to plan this excursion early in your stay, so you have time to reschedule if needed.

Lastly, remember that Alghero — like many tourist destinations in Sardinia — can be quite expensive during the high season. Booking your accommodation and services in advance can help you save money and avoid last-minute disappointments.
