Syros is one of the smallest of the Cyclades islands, though it’s also the administrative capital of the archipelago. Not many cruise ships call here, so you’ll find the beaches are much less crowded than other islands, and the main town, Ermoupoli, is home to a fascinating mix of architectural styles.

The volcanic island of Santorini (known officially as Thira) is one of the most spectacularly beautiful in the Mediterranean. The pretty village of Oia, with its whitewashed houses and windmills tumbling down the hillside, is particularly photogenic.

The beautiful Byzantine town of Monemvasia is dramatically located on a steep chunk of rock, originally a coastal headland until an earthquake in AD 375 turned it into an island. Nowadays access is via a narrow causeway, and the pretty streets of the medieval citadel are home to more churches than people.

Rugged Kefalonia is the largest of the Ionian islands, and remains unspoilt by tourism despite earning fame as the setting for ‘Captain Corelli’s Mandolin’. The island rewards exploration, with some splendid beaches and lovely little villages, and the vineyards here produce some excellent wines.

Situated on a small island at the southern entrance to the Venetian Lagoon, Chioggia is a pleasant fishing port that is sometimes described as a ‘miniature Venice’, complete with canals and some attractive historical architecture.

The largest town on Slovenia’s sliver of Adriatic coastline, Koper has an attractive medieval centre and some impressive Venetian architecture. There is also a sizeable Italian community here, reflected in the bilingual road signs, and it's a short drive across the border to the former Habsburg city of Trieste.

Croatia’s second city enjoys a dramatic setting, hugging a sweeping bay against a backdrop of sheer grey mountains. Split's labyrinthine old town is contained within the remarkable Roman ruins of Diocletian’s Palace, a UNESCO World Heritage Site, and spills out onto the buzzing seafront Riva promenade.

We never fail to be moved when we see the terracotta roofs and honey-golden walls of Dubrovnik, and a stroll around the perfectly preserved old town is a highlight of any visit to the Dalmatian coast. Make sure you take the time to walk around the walls and soak up the marvellous sea views.

Kotor sits at the head of a beautiful, fjord-like bay, hemmed in by glowering mountains. The compact, walled old town is Montenegro’s star attraction, a warren of little alleyways and shady squares that is often described as a ‘mini Dubrovnik’.

The lovely town of Sorrento, draped across rugged cliffs overlooking the Bay of Naples, has been charming visitors since the days of the Grand Tour. The Renaissance palaces and many craft shops make Sorrento an attractive destination in its own right, and it’s also a jumping off point for Capri, Pompeii and the Amalfi Coast.

One of the world’s great cities, Rome continues to dazzle and delight visitors with a potent mix of architectural marvels, continent-defining history and buzzing nightlife. The Colosseum, the Vatican and the Forum are among the big ticket items, with the crowds to match, though in truth you will find history around almost every corner.

The faded port town of Livorno serves as a gateway to Tuscany’s star attractions. Wonderful Florence, the cradle of the Renaissance, is resplendent with beautiful architecture and unrivalled artistic treasures, while nearby Pisa is of course famous for its precarious Leaning Tower.

The colourful facades along Portovenere’s UNESCO-listed harbourfront make this one of the most picturesque villages on the Ligurian coast, and it has often been described as the ‘sixth town’ of the Cinque Terre. Wandering the narrow alleyways is a delight, and it’s worth the climb to the impressive hilltop Castle Doria.

Nice enjoys a marvellous setting on one of the most glorious stretches of the Côte d’Azur, the sweeping Bay of Angels, so it’s no wonder that tourists have been flocking here since the 19th century.

From the warren-like medieval streets of the Barri Gòtic to the fantastical modernist architecture of Antoni Gaudí, from the dizzy heights of Mount Tibidabo to the golden sands of Barceloneta, there’s never a dull moment in Barcelona.

Mallorca is renowned for its beaches, ranging from big, bustling resorts to small, secluded coves. The island interior offers ruggedly beautiful scenery and quaint little towns, while the charming capital, Palma, boasts an attractive old quarter dominated by the imposing Gothic cathedral.

Sovereignty of ‘The Rock’ has been a thorny issue ever since Gibraltar was ceded to Britain in 1713, though on the ground it’s clear where most locals’ sympathies lie. Gibraltar is often described as ‘more British than Britain’, a curious enclave of red postboxes, double decker buses and chip shops.

Spread across steep hillsides that overlook the Rio Tejo, Lisbon’s colourful cityscape includes Gothic cathedrals, majestic monasteries and quaint museums. But for many the best times will be had wandering the narrow lanes of Lisbon’s lovely backstreets, with their great local food, wine and music.

Vigo is the biggest city in Galicia, Spain’s verdant northwest corner. The city itself is a busy fishing port with limited tourist appeal, but it’s a great base for striking out into the countryside, visiting the lovely Cíes Islands just offshore or joining the pilgrims in Santiago de Compostela, 60 miles to the north.

Bordeaux sits at the centre of the world's most famous wine region, and is home to a beguiling blend of beautiful buildings, sophisticated gastronomy and high culture. It's a marvellous place to spend some time, whether it's a day sampling wines, an evening at the opera or a night on the tiles.

Saint-Malo grew rich off the back of maritime trade and its plundering corsairs, a seafaring heritage that is still proudly on display today. It’s great fun getting lost in the streets of the walled old town, and the famous medieval abbey of Mont Saint-Michel is an easy day-trip.

Situated just 14 miles off the coast of Normandy, the sunny island of Jersey blends British seaside charm with a discernible French influence. The bustling capital, St Helier, is the perfect base for exploring the island’s beautiful beaches, wartime fortifications and superb seafood restaurants.

An important naval base and major commercial port, Cherbourg is the gateway to the many attractions of Normandy, including the Bayeux Tapestry and the beaches where the D-Day landings took place. Cherbourg’s excellent Cité de la Mer maritime museum is also well worth a visit.

Situated on the southern bank of the Seine estuary, Honfleur was once one of France’s most important ports. It was also a favourite location of Monet and the Impressionists, and art lovers may well recognise the elegant Renaissance architecture of the old harbour, the Vieux Bassin.
