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.

A stop in Amsterdam offers the chance to explore the sights of one of Europe’s most colorful, dynamic and historic cities—one with a well-earned reputation as a laid-back and inviting place for people of all stripes.

And at Dam Square, the Amsterdam’s largest public square, you can tour the Royal Palace before continuing to the tourist attractions on the Canal Belt. The iconic network of waterways that surrounds the downtown area offers a picturesque backdrop for sightseeing by bike or canal boat. Be sure to visit the floating Bloemenmarkt to peruse famed Dutch tulips, and take time to wander and window-shop among the narrow lanes of de Jordaan.

Just duck into a cozy brown café to sample a plate of bitterballen with mustard and a beer, and grab a gooey sweet stroopwafel from a street vendor as you stroll.
