When we started this annual roundup of the world's top guided tours three years ago, we sought to bring readers the most transformative, sustainable, and authentic experiences. To our delight, there's no shortage of companies that share our philosophy. Whether it's staring down a king penguin in Antarctica, sharing mole with a Oaxacan family, or watching your kids in a pickup soccer game in Sardinia, this is the sort of travel that will stick with you. We hope our 2008 picks get you inspired. To view past winners, click here.
