Adventurer and Explorer Mark Kalch completed a 153 day journey down the Amazon River, covering 6,800km, and filmed the journey along the way. Below is a cool trailer about the journey, some great footage of awesome rafting on deadly fast flowing waters as well as the long hard slog along the more tranquil meandering river course further along.
