The Amazon River and rainforest © Wexas

The wow factor: Covering 2.5 million square miles (6.5 million sq km), including half of Brazil and 40% of South America, the Amazon rainforest is vast – and if it was a country it would be the ninth largest in the world. Beginning in the Peruvian Andes, the Amazon River and its rainforest stretches across nine countries.

Did you know? Roughly 20% of the earth’s oxygen is produced by the Amazon rainforest, earning it the nickname “the lungs of the planet”, while 16% of all the world’s river water flows through the Amazon delta. The Amazon rainforest watershed also has the world’s highest level of biodiversity.

Experience: While most people go to Brazil, Peru offers a far less travelled way to see it.
