Alex Robinson talks about the adventure of a lifetime – a journey with Indigenous Amazonians to the wildest mountain in the tropical world – Aracá in the heart of the Amazon. And you can go too.

You will float along one of the Negro – one of the most beautiful rivers in the world, sipping caipirinhas on the deck of a classic Amazonian river boat. You'll paddle through the flooded forest in Jaú National Park; you'll come face to face with some of the Amazon's most elusive wildlife, from giant otters to river dolphins.

The trip culminates with a hike up the remote Serra Do Aracá  - a mountain which indigenous guide Saru Munduruku describes as a place "like the world before humans walked the earth." From gorgeous descriptions to surprising and touching anecdotes, this is a story you won't want to miss.
