After two morning excursions, scout for wildlife while the M/Y Tucano navigates along the heavily forested shore, where it's possible to stop for a visit at a settler's home carved out of the forest. In the early afternoon, cruise near an extraordinary river called Rio Jauaperi, where you'll see a kind of forest known as the varzea. Scout along the shoreline for some of the extraordinary creatures found only in this unique environment. Observe nocturnal creatures during a night excursion (weather permitting). The night shift of Amazon wildlife often includes Giant Potoo birds, with eyes glowing like coals in our headlamps, Amazon crocodiles, caiman, and cavort in the shallows of the darkness. Nighttime is also the high time for Bulldog fishing bats.

Voyage to the west side of the Rio Negro and set out to explore areas of the rainforest rarely visited by anyone else. At night, sip the national drink of Brasil, the Caipirinha, and perhaps try a bit of samba on the top deck as we glide through the starry darkness towards the confluence of the Rio Negro and the Amazon River.

Observe wildlife in the Lago Janauari Ecological Park, where the thick brown water of the Amazon flows swiftly through the forest. Around mid-day, travel to the Encontro das Aguas, a stark, several-mile-long line where the Amazon and the Negro rivers join in a turbulent maelstrom. In the afternoon, scout one of the hidden streams in the area to try to see more of the Amazon's beautiful and bizarre creatures. In the evening, join the group for a farewell dinner and prepare for an early departure in the morning.

After a hearty breakfast, disembark from the M/Y Tucano.
