Madidi is so full of life it can feel overwhelming. Scientists have recorded more than 1,000 bird species inside the park - that is more kinds of birds than in the whole of the United States and Canada combined. Jaguars, giant river otters, tapirs, spider monkeys and pink river dolphins all live here.
The park stretches from the snowy Andes Mountains all the way down to the warm Amazon lowlands. This means it has many different habitats inside one place: cloud forest, dry valleys, tropical rainforest, and rivers. Each habitat has its own unique set of animals and plants.
Indigenous communities, including the Tacana people, have lived inside Madidi for thousands of years. Their knowledge of the forest - which plants heal, which animals to look out for, how to read the weather - is extraordinary. Today, some of these communities welcome visitors and share their understanding of the rainforest.
The rivers in Madidi are home to some of the strangest freshwater fish in the world, including piranhas (which mostly eat plants and smaller fish, not people!), electric eels, and enormous catfish. The Amazon is full of surprises - many creatures are still being discovered and named for the first time.
