3. Denmark
Never mind that Denmark lost the top spot this year and is now the third-happiest country in the world.
Looking at all that Danes have to be happy about, you won't notice the slight dip while you're enjoying jazz at the Copenhagen Jazz Festival in July, hanging out with the hipsters at Queen Louise's Bridge, taking a canal tour or playing beach volleyball in front of the Royal Danish Playhouse. Prefer your music in the woods? Head to Smuk Fest ("The Beautiful Festival"), a rock/pop festival in the woods of Skanderborg held in August. Wherever you go, enjoy that Danish tradition of "hygge," sometimes translated too simply as the need for "coziness." It's really a complex sense of intimacy, community and contentment that generally happens with friends and family, and it makes for one happy country.
