While the Amazon may be better known, the Pantanal offers South America’s greatest wildlife extravaganza. This UNESCO Biosphere Reserve is the world’s largest seasonal floodplain, sprawling over 75,000 square miles in the heart of the continent and containing its densest concentration of wildlife. The vast mosaic of marsh and islands is home to 10 million caiman, 650 bird species and 100 different mammals, including capybara, maned wolf and giant river otter. The Pantanal’s freshwater wetlands support a profusion of aquatic fauna that attracts a host of predators, creating a huge, intricate food chain. At the top is the elegant and elusive jaguar—and our in-depth Pantanal adventure offers the world’s best chance to see them! On foot, by boat and 4x4, explore the verdant recesses of South America’s largest wildlife sanctuary—you'll find no more epic Pantanal safari!
