Overview
Delfin III Amazon Cruise — 4 Days
The Delfin III is the largest of the three Delfin vessels — twenty-two suites for forty-four guests, built in the Iquitos docks by local shipwrights and run as a Relais & Châteaux property. It works the Río Marañón out of Nauta, at the southern edge of the Pacaya-Samiria National Reserve, and the arrangement is simple: the ship is your hotel, and the wildlife watching happens from skiffs and kayaks that leave from its stern twice a day.
Pacaya-Samiria protects a little over two million hectares of seasonally flooded forest between the Marañón and the Ucayali — the largest reserve in Peru and the largest protected flooded forest in the Amazon basin. What that means in practice is water everywhere, and animals concentrated along its edges: pink river dolphins and the smaller grey tucuxi surfacing beside the skiff, hoatzins crashing about in the riverside vegetation, macaws crossing at first light, and sloths and monk saki monkeys in the branches over the channels.
This is a natural-history cruise rather than a dedicated birding trip. The onboard guides are naturalists covering birds, mammals, plants and the river itself, and the pace is built around comfort — early skiff, breakfast, late-morning excursion, siesta through the heat, afternoon out again. If you want a hard birding itinerary with a specialist guide and dawn-to-dusk field time, say so when you enquire and we will tell you honestly whether this ship or one of our lodge-based Amazon trips fits you better.

Day by Day
Itinerary
Day 1 — Iquitos, Nauta and the first night out
You are met at Iquitos airport and driven the 95 km of paved road south to Nauta, where the Delfin III is moored. After boarding, orientation and dinner, the first skiff goes out after dark for a night safari — caimans, frogs, nightjars and potoos along the banks.
Day 2 — Amazon Natural Park and the Yanayacu-Pucate
The morning is a visit to the Amazon Natural Park and a ceremony with a local shaman. In the afternoon the skiffs run into the Yanayacu-Pucate river system inside the reserve, with kayaking on the quieter channels and piranha fishing where the water allows.
Day 3 — Fundo Casual and the Unión de los Ríos
A trail walk at Fundo Casual on terra firme — high ground that never floods, and a completely different set of birds from the várzea. Later a community visit and the Unión de los Ríos, the confluence where the Marañón and the Ucayali become the Amazon.
Day 4 — Disembarkation
A last morning on board, then disembarkation at Nauta with a stop at the tropical fish aquarium and the meliponas — the stingless native bees — before the transfer to Iquitos airport.

“Alfredo with Wild Andes provided a wonderful vacation for my sister, cousin, and myself. He volunteered to coordinate all the tour including the Amazon and Lima environs. We are birders and he ensured that we had the best birding experience. We saw over 240 species of birds!”

“I recently returned from an 8-day custom expedition to Manu National Park with Wild Andes Tours and I could not be happier with the experience. This was my first time in the Amazon, so I wanted something truly personal and far from the typical “off-the-shelf” tour.”

“I had an amazing few days with Wild Andes Tours and can honestly say it was one of the highlights of my trip to Peru. I joined a three-day trip to Junín hoping to see a few dream species, especially the Pampas Cat.”

Which species can I expect to see?
Key targets include Hoatzin, Horned Screamer, Wattled Jacana, Black-collared Hawk, Ringed Kingfisher, among others.
Is this a birding tour?
Not as it stands. The Delfin III carries naturalist guides who cover birds, mammals and the forest as a whole, and the rhythm is a comfortable one. The bird list is still long — Pacaya-Samiria is superb — but if you want a specialist bird guide and dawn-to-dusk field time, tell us and we will compare it honestly against our lodge-based Amazon trips.
High water or low water — which is better?
High water, roughly November to June, floods the forest and lets the skiffs and kayaks paddle in among the trees; it is the more atmospheric season. Low water, June to November, exposes beaches and riverbanks, which concentrates wildlife along the edges and makes walking easier. Neither is wrong. The wildlife is there all year.
Why do you sell this at Delfin's own price?
Because we are an authorised seller and are paid a commission by Delfin, not by you. You pay exactly what you would pay booking direct, and you get our help planning the rest of your Peru trip around it.
