9-Day Greek Isles from Barcelona to Athens: Italy, France & Greece

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.

The port of Nice is a vibrant gateway to the French Riviera, offering a rich tapestry of history, stunning architecture, and delectable local cuisine. Must-do experiences include savoring local specialties at the bustling Cours Saleya Market and exploring the charming streets of Vieux Nice. The best time to visit is during the spring and early fall when the weather is mild and the city is alive with cultural festivities.

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.

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.

Santorini, the ancient volcanic caldera rising from the Aegean, is Greece's most theatrical landscape — a crescentic island of sheer white cliffs plunging into an indigo sea, its clifftop villages of Fira and Oia draped in bougainvillea and culminating in the world's most photographed sunset. The island's unique Assyrtiko wine, grown on ancient ungrafted vines in volcanic pumice, is one of the Mediterranean's greatest expressions of terroir. Byzantine frescoes of extraordinary beauty fill the Prehistoric Museum of Thera. The volcanic black and red sand beaches of Perissa and Perivolos are unlike any others in Greece. April through June and September through October offer the finest conditions.

Mykonos is the Aegean at its most seductive — a labyrinth of bougainvillea-draped whitewashed alleys designed to disorient pirates (and occasionally visitors) leading to Kástro, the medieval hilltop quarter overlooking Little Venice, where balconied houses hang directly above the sea. The island's famous windmills, perched on a ridge above the old harbour, are best photographed at golden hour as pelicans patrol the waterfront below. Visit the sacred archaeological island of Delos — a 30-minute boat crossing — for one of the most significant ancient sites in the Greek world. May, June, and September offer the perfect balance of warmth, light, and bearable crowds.

Heraklion, the capital of Crete, is a historic port city rich in Minoan heritage and Venetian architecture, making it an essential stop for cruise travelers. Must-do experiences include exploring the Palace of Knossos and indulging in local dishes like moussaka and dakos. The best season to visit is during the spring and early fall when the weather is mild and the local festivals are in full swing.

Piraeus, the bustling port city of Athens, is a vibrant blend of ancient history and modern charm, inviting travelers to explore its rich culture. Must-do experiences include savoring traditional Greek dishes at the Varvakeios Agora and embarking on day trips to nearby islands like Symi and Nydri. The best time to visit is during the spring and fall when the weather is pleasant and the tourist crowds are fewer.
