Reykjavík is a world capital with a small-town feel. We tour the city's endearing sights, get to know the uniquely Icelandic way of life, and take a dip in a thermal pool. Then we side-trip into majestic Icelandic nature: its famous Blue Lagoon; the classic Golden Circle, bubbling geysers, thundering waterfalls, and otherworldly scenery; and Snæfellsnes Peninsula, an "Iceland-in-miniature" loop.

Europe's ultimate road trip is the 800-mile loop around Iceland on Highway 1 — the Ring Road. We visit the geothermal hot zone of Lake Mývatn, the rugged Eastfjords, the glacier lagoons of the Southeast, the waterfalls and beaches of the South Coast, and side trip to the Westman Islands to see puffins. We also break for insightful folk museums, sod-roofed settlements, and a little whale watching.

In Kraków, we linger on one of Europe's most crowd-pleasing squares, marvel at past glories in art galleries and at Wawel Castle, and savor Polish cuisine — including a lesson in making pierogi by hand. Nearby, the communist-planned town of Nowa Huta offers a nostalgic spin through the Cold War days, while the sobering concentration camp memorial of Auschwitz-Birkenau honors victims of the Nazis.

Warsaw, the heartbeat of contemporary Poland, is gilded with a grand palace, home to a hard-fought 20th-century history, and busy with Chopin concerts. After a stop at the gingerbread bakeries in red-brick Toruń, we ogle the massive Teutonic Knight fortress of Malbork. Finishing in maritime Gdańsk, we experience handsome Hanseatic townhouses, amber jewelry, and stirring Solidarity history.

From north to south, Italy is a nonstop highlight reel. On this whirlwind look back through our travels, we sample la dolce vita in seductive Venice and Renaissance titan Florence, then soak up the Italian Riviera and the hill towns of Tuscany and Umbria. We touch down in the historical epicenter of Rome, embrace intense Naples and the Amalfi Coast, and finish amid the beautiful chaos of Sicily.

We set a course on a tranquil cruise of the rivers and canals of France's Burgundy region. Aboard a century-old barge-turned-hotel, we're treated to a relaxing pace and natural beauty — plus plenty of gourmet meals and fine wine. Stops for a hike or bike ride help us work up our next appetite, and a château lord welcomes us to taste the vintages of the famed Côte d'Or. 

Paris is a world-class city — but also one that to millions is simply home. On this adventure, we're going local. We start at the city's proud symbol, the Eiffel Tower, then cruise the Seine before exploring a few distinctive neighborhoods. We visit the market for fresh food and flowers, window-shop along trendy streets, and cap our tour with a nighttime ride through the sparkling City of Light.
