Fusina (Venice) to Rome (Civitavecchia)

Venice, approached from the Fusina port across its luminous lagoon, remains one of the world's most extraordinary cities — a thousand-year-old republic built on 118 islands and laced with canals, palaces, and masterpieces. Must-dos include riding the Grand Canal by vaporetto, savouring cicchetti at a traditional bacaro, and visiting the colourful islands of Murano and Burano. April through June and September through November offer the finest light and the most manageable crowds.

Dubrovnik, Croatia's stunning port city, is a blend of rich history, dramatic architecture, and vibrant culture, making it a must-visit destination. Don't miss a stroll along the city walls for breathtaking views and savor local dishes like "peka" and "black risotto." The best time to visit is in late spring or early fall when the weather is pleasant and the crowds are thinner.

Purpose-built as a Medici utopia in the late sixteenth century, Livorno was conceived from the outset as a city without discrimination — its founding Leggi Livornine granted equal rights to Jews, Christians, Muslims, and merchants of every nation, making it one of the most cosmopolitan cities in Renaissance Europe. Today, the Venetian-style canals of the Venezia Nuova quarter reflect colourful palazzi with a distinctly faded glamour, while the Mercato Centrale's fish counters display the cacciucco ingredients — a robust Livornese brodetto of five sea creatures — that make this port city a pilgrimage for serious eaters. Day trips to Pisa and Lucca are effortless from here. The season runs April through October.

Barcelona is the city where Roman history, Gothic grandeur, and Gaudí's delirious Modernisme collide in a Mediterranean coastal capital of astonishing energy and beauty. The Sagrada Família — still under construction after 140 years — continues its audacious ascent toward completion, while the Gothic Quarter's Roman-era foundations and the Passeig de Gràcia's extraordinary concentration of Modernisme masterpieces reward days of exploration. For a complete sensory experience, lose an afternoon in the covered labyrinth of La Boqueria market before descending to the waterfront for Catalan seafood at its finest. May through June and September through October offer the most pleasant weather; the city connects directly to Paris by overnight train.

Alicante, a historic port city on Spain's Costa Blanca, captivates visitors with its rich history, stunning architecture, and vibrant culinary scene. Must-do experiences include savoring traditional paella by the seaside and exploring the bustling Mercado Central. The best time to visit is during the spring or early fall when the weather is pleasantly warm and the city is alive with festivities.

Saint-Tropez is the legendary Côte d'Azur fishing port turned global glamour destination, where Provençal authenticity endures beneath the mythology of yachts and celebrities. Must-dos include browsing the Musée de l'Annonciade's Fauvist masterpieces, tasting tarte tropézienne and fresh-caught rouget, and strolling the Sentier du Littoral coastal path to hidden coves. May through June and September through October offer the best weather with fewer crowds.

Valletta, Europe's smallest capital, is a fortress city of exceptional grandeur raised from bare limestone in just fifteen years after the Knights of St. John repelled the great Ottoman siege of 1565 — its rigid Renaissance grid of sun-drenched streets concealing a density of baroque palaces, gilded oratories, and subterranean World War II shelters unrivaled anywhere in the Mediterranean. The Grand Harbour, framed by golden bastions plunging into startlingly blue water, offers one of the most dramatically photogenic arrivals in the world for arriving vessels. Spring and autumn deliver the most comfortable temperatures for exploring this UNESCO-listed gem.

Tucked at the head of a deep Ligurian harbour that Byron and Shelley named the Gulf of Poets, La Spezia serves as the ideal base for exploring the Cinque Terre — five cliff-hanging fishing villages threaded by ancient paths above a turquoise sea. The town itself rewards exploration: the Museo Amedeo Lia houses one of Italy's finest private collections of medieval and Renaissance art, and the naval museum reflects La Spezia's long maritime history. A boat excursion to Portovenere and the island of Palmaria, or a trail walk between Vernazza and Corniglia, constitutes a perfect day from port. Best visited April through June and September through October, avoiding the summer heat and peak crowds.

Catania is Sicily's dramatic second city, built from the black volcanic stone of Mount Etna and layered with Greek, Roman, and baroque heritage dating to 729 BC. Visitors should not miss the riotous Pescheria fish market and a tasting of authentic pasta alla Norma, followed by an excursion to the summit of Etna for views stretching to the Aeolian Islands. The best months to visit are April through June and September through October, when mild temperatures and thinner crowds allow the city's baroque streetscapes and extraordinary cuisine to be savored at a leisurely, unhurried pace.

Salerno is a historic Campanian port city nestled between the Amalfi Coast and Cilento National Park, home to Europe's first medieval medical school and a magnificent Romanesque cathedral with Byzantine bronze doors. Visitors should not miss the Lungomare Trieste promenade at sunset and a plate of hand-rolled scialatielli ai frutti di mare in the atmospheric old town. The mild Mediterranean climate makes Salerno enchanting year-round, though late spring through early autumn offers the most luminous light and the fullest expression of its coastal character.

Sardinia is a rugged, history-rich island in the western Mediterranean renowned for its luminous turquoise waters, bronze-age nuraghi towers, and a fiercely independent culinary tradition anchored by porceddu roast suckling pig and hand-pinched culurgiones pasta. Visitors should explore the Costa Smeralda's granite coves by boat and venture inland to taste Cannonau wines in centuries-old vineyards. The ideal season stretches from May through October, with late September offering warm seas, golden light, and blissful absence of peak-summer crowds.

Purpose-built as a Medici utopia in the late sixteenth century, Livorno was conceived from the outset as a city without discrimination — its founding Leggi Livornine granted equal rights to Jews, Christians, Muslims, and merchants of every nation, making it one of the most cosmopolitan cities in Renaissance Europe. Today, the Venetian-style canals of the Venezia Nuova quarter reflect colourful palazzi with a distinctly faded glamour, while the Mercato Centrale's fish counters display the cacciucco ingredients — a robust Livornese brodetto of five sea creatures — that make this port city a pilgrimage for serious eaters. Day trips to Pisa and Lucca are effortless from here. The season runs April through October.

Rome's ancient maritime gateway since the Emperor Trajan commissioned its harbour in 106 AD, Civitavecchia is the natural prologue to the Eternal City — just seventy minutes southeast by express rail. The port's Renaissance fortress, designed in part by Michelangelo, anchors a working waterfront that has welcomed travellers for millennia. Beyond Rome's unmissable monuments, consider an afternoon in the Civitavecchia thermal baths, drawing on mineral waters prized since antiquity. Spring and autumn offer the ideal balance of mild weather and manageable crowds for exploring the capital's layered history.
