Welcome to the happiest country on earth, at least according to the United Nation’s World Happiness Report. Visit Denmark, and you’ll notice the people in this compact nation, that captured the world’s attention more than a thousand years ago when the Vikings took to the seas and ravaged a big chunk of Europe, seem to be smiling more than usual thanks to a good work-life balance and safe homeland among other factors. For visitors, Denmark is a fantastic blend of old and new, where sleek modern cities, like Copenhagen, exist in harmony with centuries old castles and Viking ring forts. And the country is not lacking in experiences. There is the charm of cosmopolitan Copenhagen, but this pancake flat country is also home to one of Europe’s largest rock festivals, Roskilde, as well as the first Legoland, located next to the original Lego factory, which has been open since 1968!
