The hills around Trieste serve up crisp whites and elegant reds that shine in Friuli wineries. When it comes to things to do in Trieste, you’re spoiled for choice: stroll across the sweeping Piazza Unità d’Italia, climb up to Castello di Miramare, dive into literary history, or just spend the afternoon sipping espresso in one of Europe’s grandest cafés.

What are the best things to do in Trieste?

Start your day at Piazza Unità d’Italia

Head straight to Piazza Unità d’Italia, the largest square in Europe that opens directly onto the sea. It’s a jaw-dropping space framed by grand neoclassical buildings, with the Adriatic shimmering just beyond. The architecture whispers of Vienna, thanks to Trieste’s Habsburg past, but the vibe is unmistakably Italian. One of the best things to do in Trieste? Grab a table at Caffè degli Specchi, one of Italy’s oldest and most iconic coffeehouses, and sip a cappuccino as the city flows around you.

Visit Castello di San Giusto

Rising above Trieste’s rooftops, Castello di San Giusto rewards the climb with panoramic views over the city and the Adriatic Sea. This former fortress is a must for anyone curious about Trieste’s layered past, offering insight into centuries of military strategy and borderland tension. Right next door, step into the Cattedrale di San Giusto, where quiet mosaics and ancient stones echo Roman and medieval legacies. It’s a peaceful, history-rich corner of the city that invites you to slow down and take it all in.

Explore the Canal Grande

One of Trieste’s most photogenic spots, the Canal Grande is lined with pastel-toned buildings and bobbing boats, capturing the city’s laid-back elegance. It’s especially dreamy at sunset, when the light dances off the water and the cafés start to fill. Stop for a coffee at a canal-side terrace, snap a photo with the statue of James Joyce, and soak in the city’s literary soul and rich coffee culture, two things Trieste does better than almost anywhere else in Italy.

Discover culture at Revoltella Museum

If you’re into art with a side of city views, the Revoltella Museum is a must. Founded in the 19th century by local art patron Pasquale Revoltella, this elegant museum houses an impressive collection that spans from neoclassicism to contemporary works. Each floor offers something new: paintings, sculptures, and design, all set within a grand palace. Don’t skip the top floor: the rooftop terrace offers sweeping views over Trieste, making your cultural detour even more rewarding.

Uncover Roman history at the Arco di Riccardo

Tucked away in the narrow streets of Trieste’s Old Town, the Arco di Riccardo catches you off guard in the best way. This ancient Roman arch has stood here since the 1st century AD, blending quietly into the everyday life around it. It’s the kind of spot you stumble upon while exploring and suddenly feel connected to centuries of history. A must-see for curious wanderers and anyone chasing those unexpected, magical finds.

Catch the best views at Faro della Vittoria

Rising proudly above Trieste on the Gretta Hill, the Faro della Vittoria (Victory Lighthouse) isn’t just a beacon for ships, it’s a landmark of light, history, and breathtaking panoramas. Built after World War I to honor fallen sailors, this 223-foot monument combines maritime purpose with national pride. Climb to the top on open days and you’ll be rewarded with one of the most striking aerial views over the Gulf of Trieste, the Adriatic Sea, and the red-roofed cityscape below.

Wander at Miramare Castle along the Gulf of Trieste

Sitting like a dream above the Gulf of Trieste, Miramare Castle is one of those spots that makes you stop and stare. Built in the 19th century for Archduke Ferdinand Maximilian of Austria, this white-stone beauty has serious fairytale energy, with its towers, lush gardens, and views that stretch endlessly across the Adriatic. Step inside to explore richly decorated rooms still dressed in original furnishings, then wander the sprawling seaside park that wraps around the cliffside.

Unwind in the coastal charm of Muggia

Just a 25-minute ride south of Trieste, Muggia feels like slipping into a pocket of relaxed, seaside magic. This little fishing town is the only Istrian settlement in Italy, and it shows, think Venetian-style facades, colorful harborside houses, and a laid-back vibe that’s perfect for a slow afternoon. Stroll through its tiny historic center, grab fresh seafood by the marina, and soak up Adriatic sunshine far from the crowds.

Cross into Slovenia for a breezy escape to Koper

Looking to add an international twist without straying far? Just across the border from Trieste, 29 minutes by car, the Slovenian port city of Koper is the perfect nearby getaway. With its Venetian-style old town, breezy seafront promenade, and laid-back cafés, Koper blends Mediterranean charm with a slower pace. Climb the Bell Tower in Tito Square for panoramic views, stroll through cobbled alleys lined with pastel buildings, or sip a local white wine along the marina. It’s the ideal quick hop if you want to explore beyond Italy, without the long drive.

Step into two worlds on a day trip to Gorizia

Just 45 minutes from Trieste, Gorizia offers one of the most fascinating cross-cultural experiences in Northern Italy. This quiet border town is uniquely split with Slovenia (where it becomes Nova Gorica), creating a rare blend of Italian elegance and Slavic soul. Wander through its charming streets, explore the medieval Castle of Gorizia with sweeping views of both countries, and dive into local museums that tell stories of borders, wars, and peace. For a quirky stop, don’t miss Piazza Transalpina, where you can literally place one foot in Italy and the other in Slovenia.
