Lying near the head of Southampton Water, a peninsula between the estuaries of the Rivers Test and Itchen, Southampton is Britain’s largest cruise port. It has been one of England’s major ports since the Middle Ages, when it exported wool and hides from the hinterland and imported wine from Bordeaux. The city suffered heavy damage during World War Two and as a result the centre has been extensively rebuilt, but there are still some interesting medieval buildings including the Bargate, one of the finest city gatehouses in England.

Edinburgh is to London as poetry is to prose, as Charlotte Brontë once wrote. One of the world's stateliest cities and proudest capitals, it's built—like Rome—on seven hills, making it a striking backdrop for the ancient pageant of history. In a skyline of sheer drama, Edinburgh Castle watches over the capitalcity, frowning down on Princes Street’s glamour and glitz. But despite its rich past, the city’s famous festivals, excellent museums and galleries, as well as the modern Scottish Parliament, are reminders that Edinburgh has its feet firmly in the 21st century. Nearly everywhere in Edinburgh (the burgh is always pronounced burra in Scotland) there are spectacular buildings, whose Doric, Ionic, and Corinthian pillars add touches of neoclassical grandeur to the largely Presbyterian backdrop. Large gardens are a strong feature of central Edinburgh, where the city council is one of the most stridently conservationist in Europe. Arthur's Seat, a mountain of bright green and yellow furze, rears up behind the spires of the Old Town. This child-size mountain jutting 822 feet above its surroundings has steep slopes and little crags, like a miniature Highlands set down in the middle of the busy city. Appropriately, these theatrical elements match Edinburgh's character—after all, the city has been a stage that has seen its fair share of romance, violence, tragedy, and triumph. Modern Edinburgh has become a cultural capital, staging the Edinburgh International Festival and the Fringe Festival in every possible venue each August. The stunning Museum of Scotland complements the city’s wealth of galleries and artsy hangouts. Add Edinburgh’s growing reputation for food and nightlife and you have one of the world’s most beguiling cities. Today the city is the second most important financial center in the United Kingdom, and the fifth most important in Europe. The city regularly is ranked near the top in quality-of-life surveys. Accordingly, New Town apartments on fashionable streets sell for considerable sums. In some senses the city is showy and materialistic, but Edinburgh still supports learned societies, some of which have their roots in the Scottish Enlightenment. The Royal Society of Edinburgh, for example, established in 1783 "for the advancement of learning and useful knowledge," remains an important forum for interdisciplinary activities. Even as Edinburgh moves through the 21st century, its tall guardian castle remains the focal point of the city and its venerable history. Take time to explore the streets—peopled by the spirits of Mary, Queen of Scots; Sir Walter Scott; and Robert Louis Stevenson—and pay your respects to the world's best-loved terrier, Greyfriars Bobby. In the evenings you can enjoy candlelit restaurants or a folk ceilidh (pronounced kay-lee, a traditional Scottish dance with music), though you should remember that you haven't earned your porridge until you've climbed Arthur's Seat. Should you wander around a corner, say, on George Street, you might see not an endless cityscape, but blue sea and a patchwork of fields. This is the county of Fife, beyond the inlet of the North Sea called the Firth of Forth—a reminder, like the mountains to the northwest that can be glimpsed from Edinburgh's highest points, that the rest of Scotland lies within easy reach.

The port of Invergordon is your gateway to the Great Glen, an area of Scotland that includes Loch Ness and the city of Inverness. Inverness, the capital of the Highlands, has the flavor of a Lowland town, its winds blowing in a sea-salt air from the Moray Firth. The Great Glen is also home to one of the world's most famous monster myths: in 1933, during a quiet news week, the editor of a local paper decided to run a story about a strange sighting of something splashing about in Loch Ness. But there's more to look for here besides Nessie, including inland lochs, craggy and steep-sided mountains, rugged promontories, deep inlets, brilliant purple and emerald moorland, and forests filled with astonishingly varied wildlife, including mountain hares, red deer, golden eagles, and ospreys.

Trendy stores, a booming cultural life, fascinating architecture, and stylish restaurants reinforce Glasgow's claim to being Scotland's most exciting city. After decades of decline, it has experienced an urban renaissance uniquely its own. The city’s grand architecture reflects a prosperous past built on trade and shipbuilding. Today buildings by Charles Rennie Mackintosh hold pride of place along with the Zaha Hadid–designed Riverside Museum.Glasgow (the "dear green place," as it was known) was founded some 1,500 years ago. Legend has it that the king of Strathclyde, irate about his wife's infidelity, had a ring he had given her thrown into the river Clyde. (Apparently she had passed it on to an admirer.) When the king demanded to know where the ring had gone, the distraught queen asked the advice of her confessor, St. Mungo. He suggested fishing for it—and the first salmon to emerge had the ring in its mouth. The moment is commemorated on the city's coat of arms.The medieval city expanded when it was given a royal license to trade; the current High Street was the main thoroughfare at the time. The vast profits from American cotton and tobacco built the grand mansions of the Merchant City in the 18th century. In the 19th century the river Clyde became the center of a vibrant shipbuilding industry, fed by the city’s iron and steel works. The city grew again, but its internal divisions grew at the same time. The West End harbored the elegant homes of the newly rich shipyard owners. Down by the river, areas like the infamous Gorbals, with its crowded slums, sheltered the laborers who built the ships. They came from the Highlands, expelled to make way for sheep, or from Ireland, where the potato famines drove thousands from their homes.During the 19th century the population grew from 80,000 to more than a million. And the new prosperity gave Glasgow its grand neoclassical buildings, such as those built by Alexander "Greek" Thomson, as well as the adventurous visionary buildings designed by Charles Rennie Mackintosh and others who produced Glasgow’s Arts and Crafts movement. The City Chambers, built in 1888, are a proud statement in marble and gold sandstone, a clear symbol of the wealthy and powerful Victorian industrialists' hopes for the future.The decline of shipbuilding and the closure of the factories led to much speculation as to what direction the city would take now. The curious thing is that, at least in part, the past gave the city a new lease of life. It was as if people looked at their city and saw Glasgow’s beauty for the first time: its extraordinarily rich architectural heritage, its leafy parks, its artistic heritage, and its complex social history. Today Glasgow is a vibrant cultural center and a commercial hub, as well as a launching pad from which to explore the rest of Scotland, which, as it turns out, is not so far away. In fact, it takes only 40 minutes to reach Loch Lomond, where the other Scotland begins.

Before English and Scottish settlers arrived in the 1600s, Belfast was a tiny village called Béal Feirste ("sandbank ford") belonging to Ulster's ancient O'Neill clan. With the advent of the Plantation period (when settlers arrived in the 1600s), Sir Arthur Chichester, from Devon in southwestern England, received the city from the English Crown, and his son was made Earl of Donegall. Huguenots fleeing persecution from France settled near here, bringing their valuable linen-work skills. In the 18th century, Belfast underwent a phenomenal expansion—its population doubled every 10 years, despite an ever-present sectarian divide. Although the Anglican gentry despised the Presbyterian artisans—who, in turn, distrusted the native Catholics—Belfast's growth continued at a dizzying speed. The city was a great Victorian success story, an industrial boomtown whose prosperity was built on trade, especially linen and shipbuilding. Famously (or infamously), the Titanic was built here, giving Belfast, for a time, the nickname "Titanic Town." Having laid the foundation stone of the city's university in 1845, Queen Victoria returned to Belfast in 1849 (she is recalled in the names of buildings, streets, bars, monuments, and other places around the city), and in the same year, the university opened under the name Queen's College. Nearly 40 years later, in 1888, Victoria granted Belfast its city charter. Today its population is nearly 300,000, tourist numbers have increased, and this dramatically transformed city is enjoying an unparalleled renaissance.This is all a welcome change from the period when news about Belfast meant reports about "the Troubles." Since the 1994 ceasefire, Northern Ireland's capital city has benefited from major hotel investment, gentrified quaysides (or strands), a sophisticated new performing arts center, and major initiatives to boost tourism. Although the 1996 bombing of offices at Canary Wharf in London disrupted the 1994 peace agreement, the ceasefire was officially reestablished on July 20, 1997, and this embattled city began its quest for a newfound identity.Since 2008, the city has restored all its major public buildings such as museums, churches, theaters, City Hall, Ulster Hall—and even the glorious Crown Bar—spending millions of pounds on its built heritage. A gaol that at the height of the Troubles held some of the most notorious murderers involved in paramilitary violence is now a major visitor attraction.Belfast's city center is made up of three roughly contiguous areas that are easy to navigate on foot. From the south end to the north, it's about an hour's leisurely walk.

Dublin is making a comeback. The decade-long "Celtic Tiger" boom era was quickly followed by the Great Recession, but The Recovery has finally taken a precarious hold. For visitors, this newer and wiser Dublin has become one of western Europe's most popular and delightful urban destinations. Whether or not you're out to enjoy the old or new Dublin, you'll find it a colossally entertaining city, all the more astonishing considering its intimate size.It is ironic and telling that James Joyce chose Dublin as the setting for his famous Ulysses, Dubliners, and A Portrait of the Artist as a Young Man because it was a "center of paralysis" where nothing much ever changed. Which only proves that even the greats get it wrong sometimes. Indeed, if Joyce were to return to his once-genteel hometown today—disappointed with the city's provincial outlook, he left it in 1902 at the age of 20—and take a quasi-Homeric odyssey through the city (as he so famously does in Ulysses), would he even recognize Dublin as his "Dear Dirty Dumpling, foostherfather of fingalls and dotthergills"?For instance, what would he make of Temple Bar—the city's erstwhile down-at-the-heels neighborhood, now crammed with cafés and trendy hotels and suffused with a nonstop, international-party atmosphere? Or the simple sophistication of the open-air restaurants of the tiny Italian Quarter (named Quartier Bloom after his own creation), complete with sultry tango lessons? Or of the hot–cool Irishness, where every aspect of Celtic culture results in sold-out theaters, from Once, the cult indie movie and Broadway hit, to Riverdance, the old Irish mass-jig recast as a Las Vegas extravaganza? Plus, the resurrected Joyce might be stirred by the songs of Hozier, fired up by the sultry acting of Michael Fassbender, and moved by the award-winning novels of Colum McCann. As for Ireland's capital, it's packed with elegant shops and hotels, theaters, galleries, coffeehouses, and a stunning variety of new, creative little restaurants can be found on almost every street in Dublin, transforming the provincial city that suffocated Joyce into a place almost as cosmopolitan as the Paris to which he fled. And the locals are a hell of a lot more fun! Now that the economy has finally turned a corner, Dublin citizens can cast a cool eye over the last 20 crazy years. Some argue that the boomtown transformation of their heretofore-tranquil city has permanently affected its spirit and character. These skeptics (skepticism long being a favorite pastime in the capital city) await the outcome of "Dublin: The Sequel," and their greatest fear is the possibility that the tattered old lady on the Liffey has become a little less unique, a little more like everywhere else.Oh ye of little faith: the rare ole gem that is Dublin is far from buried. The fundamentals—the Georgian elegance of Merrion Square, the Norman drama of Christ Church Cathedral, the foamy pint at an atmospheric pub—are still on hand to gratify. Most of all, there are the locals themselves: the nod and grin when you catch their eye on the street, the eagerness to hear half your life story before they tell you all of theirs, and their paradoxically dark but warm sense of humor. It's expected that 2016 will be an extra-special year in the capital, as centenary celebrations of the fateful 1916 Easter Rising will dominate much of the cultural calendar.

Once a northern defense post against Irish raiders, Holyhead later became best known as a ferry port for Ireland. The dockside bustle is not matched by the town, however, which maintains just a small population. Nonetheless, thousands of years of settlement have given Holyhead rich historical ruins to explore, with more in the surrounding hiking friendly landscape.

The largest town in the Southeast and Ireland's oldest city, Waterford was founded by the Vikings in the 9th century and was taken over by Strongbow, the Norman invader, with much bloodshed in 1170. The city resisted Cromwell's 1649 attacks, but fell the following year. It did not prosper again until 1783, when George and William Penrose set out to create "plain and cut flint glass, useful and ornamental," and thereby set in motion a glass-manufacturing industry long without equal. The famed glassworks closed after the 2008 financial crisis, but Waterford Crystal has triumphantly risen again from the flames in a smaller, leaner version, opened in 2010 and now relocated to the Mall.

Nestled in the mouth of a wooded estuary, Fowey (pronounced Foy) is still very much a working china-clay port as well as a focal point for the sailing fraternity. Increasingly, it's also a favored home of the rich and famous. Good and varied dining and lodging options abound; these are most in demand during Regatta Week in mid- to late August and the annual Fowey Festival of Words and Music in mid-May. The Bodinnick and Polruan ferries take cars as well as foot passengers across the river for the coast road on to Looe.A few miles west of Fowey are a pair of very different gardens: the Eden Project, a futuristic display of plants from around the world, and the Lost Gardens of Heligan, a revitalized reminder of the Victorian age.

Lying near the head of Southampton Water, a peninsula between the estuaries of the Rivers Test and Itchen, Southampton is Britain’s largest cruise port. It has been one of England’s major ports since the Middle Ages, when it exported wool and hides from the hinterland and imported wine from Bordeaux. The city suffered heavy damage during World War Two and as a result the centre has been extensively rebuilt, but there are still some interesting medieval buildings including the Bargate, one of the finest city gatehouses in England.
