The bucolic region is also home to the country's highest mountain peak, Gerlach, popular among mountain climbers and trail hikers, and Štrbské Pleso lake, which, for nearly half the year, is frozen solid and doubles as an outdoor skating rink.
Indeed, a scan of the top 10 destinations is void of perennial favorites like London, Paris and Rome, and instead features places like Herzegovina, Bosnia and Herzegovina, Liechtenstein and Vevey, Switzerland.

Revitalization efforts have polished up the old town, with family-run eateries opening in previously boarded-up shops, and a renaissance of cultural spaces breathing new life into locations like ornate Teatro Piccinni theater and once-condemned heritage hotels like the Oriente.
6. Shetland, Scotland
The UK's northernmost point features awesome coastal trails, sightings of otters and orcas from craggy headlands and top fish and chip shops.
Created as part of the celebrations marking 300 years since Liechtenstein became a sovereign nation, the Liechtenstein Trail is a scenic 75km cross-country hiking path "twists over peak and pasture."
9. Vevey, Switzerland
Held just once every 20 years, the three-week wine festival, Fête des Vignerons, returns to Vevey in June. Visitors can line their stomachs at one of the Old Town's myriad quality eateries, offering everything from 20-course tasting menus to cheap-and-cheerful fondue, before working off their food with a swim in the lake.
10. Istria, Croatia
Expanding European flight connections make this heart-shaped peninsula easier to reach than ever. The region is home to ancient ruins, beaches, gourmet cycling tours, music festivals and truffle-hunting excursions in fall.
