Arrive in Iquitos and transfer by bus to Nauta, where the Delfin is docked. Board the Delfin and explore the ship before happy hour. Attend dinner in the dining room and, when finished, join your guides on the top observation deck to learn about your journey.

In the morning, join your guides for exploration by skiff and a jungle trail walk. Take a hike through the unique, flooded ecosystem and observe the canopy trees and buttress roots of the forest.

After lunch, sail for Yanayacu Pucate and explore the National Reserve. Take an aluminum skiff to sail deeper into the rainforest, viewing wonderful flora and fauna, paddle boarding, and swimming with dolphins.

In the morning, take a catamaran journey and arrive at the only canopy walkway in the area. The walkway provides spectacular views of the Amazon's wildlife and vegetation. Hike through the pristine and unique ecosystem of the Amazon, passing through a classic tropical rainforest with emergent trees and canopy trees reaching up to 55 meters in height. Many trees have buttress roots which often extend high up the trunks, while palms are abundant and many of them have stilt roots. Biologically, this kind of forest is one of the richest habitats on earth, supporting the most species of plants and animals per unit area. Perhaps catch sight of the giant otters, which feature large bodies, dark fur, and spotted throats. The otters nest in a small stream inside the forest and are easily spooked. The forest is also ideal for spotting birds such as the bluish-fronted jacamar or collared trogons. Canoe through to Tawampa Lake and hope to see the giant arapaima, the largest freshwater fish in the world.

Eat lunch on board before arriving at Jacinto Lake or Nauta Cano, areas full of small creeks and lagoons. Sail or kayak quietly near the shore and explore marshes, streams, and oxbows. Take a skiff to try piranha fishing. There are 25 different species of piranha in the Amazon basin, including black, white and red bellied.

In the evening, begin a night safari in search of night herons, paupaques, owls, and fish bats. You may also see spectacled and black caimans.

Spend today exploring the Yarapa River. In the morning, kayak along the broad, white sandy beaches and river island. Search for shore birds such as sandpipers, terns, black skimmers, egrets, jabirus, wood storks, and kingfishers. Continue your explorations in the afternoon by skiff.

In the morning, board a skiff and stop at the village of San Francisco. Take the chance to meet the local villagers and learn about their culture, traditions, and folklore. Shop at the local market and enjoy a final kayaking opportunity. Reboard the Delfin I and enjoy lunch on board before arriving in Nauta. Visit the Rescue & Rehabilitation Center of River Mammals to learn about manatees and other threatened species. Take the hour-and-a-half bus ride back to Iquitos and transfer to the airport for your connecting flights.
