Manú National Park, deep in the Peruvian rainforest, is one of the most biodiverse places on the planet. The park and surrounding areas are home to some 10 percent of the world's bird species, countless insect species still unknown to science, and about as many tree species as are found in all of North America.

It is also home to "uncontacted" tribes such as the Mascho-Piro who have chosen to live in isolation for a century, a few of whom are slowly beginning to make contact with outsiders.

National Geographic photographer Charlie Hamilton James ventured into Manú National Park to photograph life in this remarkable park for the June 2016 issue of National Geographic magazine.

Hear James tell stories from his time living in a small village among the Matsigenka people who are beginning to make contact with some of the isolated people living in the rain forests—and enjoy his stunning photos of the people and wildlife of the Amazon.
