For centuries, this tiny nation of seafaring traders played a leading role in world history. It reclaimed 40% of its territory from the sea and produces a healthy agricultural surplus amid Europe’s most densely populated area—yet Holland manages to remain quaint and scenic. Your day begins with a canal cruise to see Amsterdam from water level, and the visit of a diamond center, watching skilled craftsmen cut and polish precious stones. Enjoy the afternoon exploring on your own, perhaps by browsing one of the many marvelous museums or looking both ways in the city where bicycles outnumber cars by four times!
