Travel a million miles from tourist hordes—and cellphone reception—to an immersive and challenging experience you will not soon forget. You’ll encounter the hunting grounds of deadly piranhas, go in search of predatory black caimans, and learn how to identify rare and ancient medicinal rainforest plants. You'll go on a jungle trek to spot the nocturnal tapir and sleep in a lakeside hammock. Then you’ll pack up your gear and paddle a canoe to a village, meet indigenous people, and marvel at the unique rhythm of life along an incredible river.
