'The most beautiful river in the world'
A river in Colombia turns different shades of colour in a natural display that happens nowhere else on Earth.
Just east of the Andes, central Colombia’s Caño Cristales is a river like no other. Reaching 100km long and sometimes called the “Liquid Rainbow”, Caño Cristales runs during certain months of the year with shades of red, blue, yellow, orange and green.
