Upon arrival at the airport, guests begin a scenic transfer by road to Nauta, where the Zafiro awaits. Once onboard, the crew greets travelers and escorts them to their suites, each featuring large windows that frame the surrounding Amazon landscape. Before the vessel sets sail, guests gather for a welcome cocktail prepared with fresh Amazonian fruits while taking in views from the observation deck or lounge. Naturalist guides then present an introduction to the expedition, explaining the river systems, ecosystems, and wildlife likely to be encountered along the route. Later in the afternoon, the first skiff excursion explores the Yacapana area, a region of flooded forest and narrow waterways that supports a wide range of birdlife, reptiles, and mammals. As evening approaches, guests set out on a guided nocturnal safari. With the help of spotlights, guides search the riverbanks for caimans while identifying frogs, insects, and other creatures active after dark. The day concludes with a welcome dinner showcasing regional Peruvian and Amazonian cuisine.
