Part of the ancestral territory of the San Juan de Yanayacu indigenous community, the Amazon Refuge Wildlife Conservation Center lies inside one of the most biologically diverse areas in the world. Visits to the center must be arranged and booked prior to arrival. Guided treks go deep into the jungle and combine hiking and cruising on the river to spot native creatures such as jaguars, monkeys, pink dolphins, caiman, and over 500 species of birds. Day trips from Iquitos are worthwhile, though it’s recommended to stay overnight in one of the cabins.
