Our Eco-Adventure programs run the gamut from general eco-adventure to specific special interests. In this program we bring you the eco-highlights of Brazil visiting Iguassu Falls and National Park including Macuco Safari, an unrivaled combination of nature and adventure providing contact with wildlife and the spectacle of the world's largest waterfalls sure to be etched in your memory forever. Next we board the Desafio and sail along the wondrous Amazon rainforest jungle and its tributaries for a first-hand view of some of our planet's most exotic, unexplored regions, and most sacred assets.
