Costa Rica

Much more than merely a tropical vacation destination, Costa Rica is the original eco-tourist mecca, where five percent of all Earth's species reside on only .01% of the planet's land mass. The country has an intense array of environmental attractions to tantalize your senses – majestic volcanoes, misty cloud forests, lush jungles, and hundreds of postcard-worthy beaches along two seductive, snaking coastlines.

Centering yourself on a surfboard or yoga mat, hanging with monkeys and toucans in rainforest-shrouded valleys, descending into bat-filled caves or ascending misty volcanic peaks, hiking, biking or zip-lining – your only limit is your return date. Plus, according to the Happy Planet Index, Costa Rica is the happiest place on Earth.
