3. Denmark

Ranked No. 1 in 2013, Denmark dropped a couple spots in the new ranking. Lined with cobblestone streets, verdant gardens, and home to hundreds of islands, it is an oasis for bliss. Denmark is the southernmost country in Scandinavia. Copenhagen, the country’s capital, has been called the world’s most liveable city and is a first-class destination for tourists.
