Day 1 Southampton, England

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.

Day 2 Le Havre, France

Le Havre, founded by King Francis I of France in 1517, is located inUpper Normandy on the north bank of the mouth of the River Seine, which isconsidered the most frequented waterway in the world. Its port is ranked thesecond largest in France. The city was originally built on marshland andmudflats that were drained in the 1500's. During WWII most of Le Havre wasdestroyed by Allied bombing raids. Post war rebuilding of the city followed thedevelopment plans of the well-known Belgian architect Auguste Perre. Thereconstruction was so unique that the entire city was listed as a UNESCO WorldHeritage Site in 2005. 

Day 4 Dun Laoghaire, Ireland

Day 5 Cobh, Ireland

Cork City's nearby harbor district has seen plenty of history. Cork Harbour's draws include Fota Island—with an arboretum, a wildlife park, and the Fota House ancestral estate—and the fishing port of Cobh.

Day 10 Sydney, Nova Scotia, Canada

If you come directly to Cape Breton via plane, ferry, or cruise ship, Sydney is where you'll land. If you're seeking anything resembling an urban experience, it's also where you'll want to stay: after all, this is the island's sole city. Admittedly, it is not the booming center it was a century ago when the continent's largest steel plant was located here (that era is evoked in Fall on Your Knees, an Oprah Book Club pick penned by Cape Bretoner Anne-Marie MacDonald). However, Sydney has a revitalized waterfront and smattering of Loyalist-era buildings that appeal to visitors. Moreover, it offers convenient access to popular attractions in the region—like the Miner's Museum in nearby Glace Bay (named for the glace, or ice, that filled its harbor in winter), the Fortress at Louisbourg, and beautiful Bras d'Or Lake.

Day 11 Halifax, Nova Scotia, Canada

Surrounded by natural treasures and glorious seascapes, Halifax is an attractive and vibrant hub with noteworthy historic and modern architecture, great dining and shopping, and a lively nightlife and festival scene. The old city manages to feel both hip and historic. Previous generations had the foresight to preserve the cultural and architectural integrity of the city, yet students from five local universities keep it lively and current. It's a perfect starting point to any tour of the Atlantic provinces, but even if you don't venture beyond its boundaries, you will get a real taste of the region.It was Halifax's natural harbor—the second largest in the world after Sydney, Australia's—that first drew the British here in 1749, and today most major sites are conveniently located either along it or on the Citadel-crowned hill overlooking it. That's good news for visitors because this city actually covers quite a bit of ground.Since amalgamating with Dartmouth (directly across the harbor) and several suburbs in 1996, Halifax has been absorbed into the Halifax Regional Municipality, and the HRM, as it is known, has around 415,000 residents. That may not sound like a lot by U.S. standards, but it makes Nova Scotia's capital the most significant Canadian urban center east of Montréal.There's easy access to the water, and despite being the focal point of a busy commercial port, Halifax Harbour doubles as a playground, with one of the world's longest downtown boardwalks. It's a place where container ships, commuter ferries, cruise ships, and tour boats compete for space, and where workaday tugs and fishing vessels tie up beside glitzy yachts. Like Halifax as a whole, the harbor represents a blend of the traditional and the contemporary.

Day 13 New York, New York, United States

From Wall Street's skyscrapers to the neon of Times Square to Central Park's leafy paths, New York City pulses with an irrepressible energy. History meets hipness in this global center of entertainment, fashion, media, and finance. World-class museums like MoMA and unforgettable icons like the Statue of Liberty beckon, but discovering the subtler strains of New York's vast ambition is equally rewarding: ethnic enclaves and shops, historic streets of dignified brownstones, and trendy bars and eateries all add to the urban buzz.
