Amacayacu National Park is rich with wildlife, including river dolphins, reptiles and birds. It’s also home to the lion marmoset, Earth’s smallest primate, and it has the largest species of fresh-water turtle and crocodile. Note that accommodation is very rustic here.
Indigenous communities live in these areas, including the Yagua, who have worked hard to protect their cultures and traditions, such as their knowledge of medicinal plants, magic, ceremonies and jungle survival skills. Leticia is also where the Colombian border meets the Amazon and crosses into Tabatinga.
Follow the river to Manaus in Brazil and even to the coast at Belem by river-boat, sleeping in a hammock for a few days.
