Costa Rica is also known as the world's happiest country! Located on the Central American isthmus between Nicaragua and Panama, Costa Rica offers a unique environment in the world. Life expectancy (78.5 years in average) is higher than its neighbors and it's very proud of having no army since 1948 ! In Costa Rica the motto is "Pura Vida" : people live happily at a smooth pace. But this does not mean that nothing is happening in the country. On the contrary! Since sustainable development became a priority, economical dynamism, entrepreneurship, and research & development are particularly highlighted for an essential purpose : to develop all the ways needed to protect the environment. For the traveler, it means preserved jungles, spectacular volcanoes, wild and isolated beaches. What a treat, hey!
