When the United Nations declared March 20 the International Day of Happiness, it recognized the relevance of "happiness and well-being as universal goals and aspirations in the lives of human beings around the world." This officially designated happy date is marking its second year. And Iceland is once again among the happiest nations in the World.
The happiest of countries -- many of which are in Scandinavia according the latest World Happiness Report -- have a robust combination of higher life expectancy, gross domestic product per capita, social support, generosity, freedom to make life choices and lower perceptions of corruption. By analyzing happiness data, officials hope to improve the world's social, economic and environmental well-being.
Get happy in the world's happiest countries.
No one should visit Iceland without taking a dip at the country's famous Blue Lagoon. The airport bus sometimes even offers paying passengers a stop there on the way to and from the airport, and the waters (and food) are divine. Or make sure you take a soak at any of the county's other naturally heated swimming pools.
If you're up for an adventure, head to Snæfellsjökull National Park to see a glacier on top of a still active volcano (although the last time it erupted was 1,900 years ago). You will spot Snæfellsjökull (Snæfell Glacier), Saxhóll volcano crater, Lóndrangar massive lava formations and Rauðfeldargjá the hidden waterfall. Snæfellsjökull was made famous by Jules Verne's "A Journey to the Center of the Earth."
Other countries on the list include Denmark, Norway, Switzerland, Netherlands, Sweden, Canada, Finland, Austria and Australia.
