Best Adventure Travel Companies {On Earth}

Ninety-percent of this outfitter's trips to popular Latin American destinations such as the Amazon rain forest and Galapagos Archipelago are customized. Instead of following a regimented itinerary, indigenous guides design their own routes based on guests' preferences to ensure pristine wildlife and cultural encounters—and the sky's the limit in terms of activities (climbing, biking, rafting, trekking, mountain biking).
