Amazon

The Amazon River begins in Peru and runs for around 6,400 kilometres before reaching the Atlantic in Brazil, carving through the largest rainforest on Earth along the way. The scale below the canopy is just as striking, with an estimated 1,300 bird species and around 40,000 types of plant life recorded across the basin. Spend even a few days here and the sheer density of life becomes the story, more than any single sighting.
