Its surroundings covering nearly half of the territory of Peru, the Amazon is the mightiest river in the world, flanked by vast stretches of pristine rainforest. International Expeditions has been exploring these waters for all of our 27 years of existence, and we continue to be amazed at all we find on our 10-day riverboat expedition.

The rainforest canopy shelters the richest and most diverse ecosystem on Earth, making it the perfect place for anyone who cares about nature. Beginning in Iquitos, the world’s furthest inland seaport, we travel upstream along the Amazon’s tributaries, going deep into the Pacaya-Samiria Reserve — the largest wetland reserve in the world. On our exclusive itinerary, you go deeper into the reserve — by far — than on any other Amazon journey, and as a result, you see much more, pure and simple. We’ll look for the Amazon’s myriad forms of wildlife — monkeys, birds, sloths and other mammals, pink and gray dolphins and many more. You might even spot the endangered giant otter or the rare harpy eagle.

Expert local naturalist guides will accompany you. Many have worked with us for more than a decade. They are the friendliest, most knowledgeable people you’ll ever meet, with an uncanny ability to find wildlife and the desire to share their knowledge. An expedition leader will also accompany you, making sure you are well looked after.
