Dover, in the county of Kent in southeast England, has understandably been one of the most important ports of entry to the country for centuries, given its location on the English Channel across from France. The famous White Cliffs of Dover greet you as you arrive, and the city has a number of historic sights, including a medieval castle. For many travelers, however, it is primarily a gateway to London. Few places can compete with England’s capital for sheer energy, atmosphere and variety. London’s vibrancy—in art, in music, in architecture—is formidable. It’s a city with not only multiple attractions, grand structures and great cultural institutions (though there are plenty of those) but also scenic parks, walkable villages and striking modern additions.Culinary pioneers are reviving traditional techniques and introducing menus that are at the forefront of the world’s premier restaurant experiences. Leg-powered sightseeing (by bike or on foot) around London maximizes opportunities for stumbling across secret alleys, courtyards housing quirky art galleries and tiny old pubs serving fresh British ales. Shoppers will want to check out the items at some of the retail emporiums known the world over as well as diminutive boutiques stocking unique souvenirs.

Often called the gateway to Europe, the port city of Rotterdam is full of old-world charm. The harbor offers amazing views and a maze of wharves and canals, along with towering spires make for a beautiful sight. Take a stroll and duck into one of the pubs or eateries along the way. Only three pre World War II buildings in the city centre have survived and are worth a look – city hall, St. Laurence church and the White House. Explore the Museum Boymans van Beuningen, which houses a unique collection dating from the 14th century, or the Museum Voor Volkenkunde – home to ethnological exhibits. Exquisite architecture can be seen in many areas of Rotterdam, most notably in the Delfshaven quarter of the city – where 18th century houses are on display. For a laugh, check out Kijk-Kubus, an upside-down house.

Belfast has emerged from decades of conflict to become one of Ireland’s most intriguing cities. In the 19th century, its location on the banks of the River Lagan made it an industrial center for ropemaking, shipbuilding, tobacco and textiles. And this legacy shaped much of its architecture: Grand Edwardian and Victorian municipal buildings and warehouses are found throughout the city alongside telltale scars of its more recent past. While the legacy of Belfast’s complex conflict known as The Troubles still looms, there are many other sides of Northern Ireland‘s capital to explore, from the quaint streets of the Cathedral Quarter to the newly regenerated Titanic Quarter, where the ill-fated RMS Titanic was constructed. Belfast is also gathering momentum as an up-and-coming gourmet destination, with a new generation of chefs producing food to get excited about. Beyond the city limits, County Down and neighboring County Antrim have a wealth of things to see and do. Any lingering negative preconceptions will evaporate after a short time in this fascinating and welcoming city.

The capital of and largest town on the 570-square-kilometer Isle of Man in the heart of the Irish Sea, Douglas lies within easy reach of Scotland, England, Wales and Northern Ireland. Cultured yet quirky, the city sits on a vast crescent bay and is the point from which everything else stems on Man. Beginning in the early 19th century, Douglas became a popular holiday resort, with tourists pouring in from the mainland to enjoy its seaside delights. Today, there are echoes of its heyday with horse-drawn trams clattering along the promenade and what appears to be a huge sand castle on the bay at St. Mary’s Isle, actually an 1832 shelter for sailors nicknamed the Tower of Refuge by famous visitor William Wordsworth. Douglas may be best known today as the launching pad for the popular Isle of Man TT motorcycle race, which takes place here every June, and as the birthplace of the wildly successful 1970s pop music band the Bee Gees. While they are often more closely associated with Australia, the brothers‘ childhood home was at 50 St. Catherine‘s Drive—a site that is marked by a blue plaque from English Heritage in recognition of its historic significance.

Corkonians are fiercely proud of their hometown, so much so that it’s jokingly referred to as the People’s Republic of Cork. And there is a lot to love about Ireland’s second city. Hugging the banks of the River Lee, it takes its name from corcaigh, the Gaelic word for “marshy.” With its origins in the 7th century, Cork enjoyed a flourishing period as a merchant center in the 18th and 19th centuries, with grand buildings like the elegant Cork City Hall bearing testimony to this status. On the north bank of the River Lee is the quaint neighborhood of Shandon with its landmark clock tower of St. Anne’s Church. The city’s heart is set on an island sandwiched between two channels of the Lee that open out into one of Europe‘s largest natural harbors at Cobh. Cobh brought the city prosperity (and also happened to be the final port of call for the ill-fated RMS Titanic). And it was from Cobh that over 2.5 million immigrants caught their final glimpse of their home country as they departed in search of a better life in the United States between 1848 and 1950. There’s a more modern side to Cork, with a thriving university quarter, pubs, bars and restaurants. Whatever your interests, you will find a side of Cork to love too.
