After taking in a game at Manaus' Arena Amazonia, which was purpose built for the World Cup in the middle of the rainforest, take advantage of your time on the ground by finding a local guide and heading out into the wild surrounds. Tour operator Frontiers Travel ferries serious fishers to the Agua Boa Amazon Lodge on charter planes. Try your hand at catching peacock bass and piranha in a region where jaguar, sloths and pink dolphins outnumber people.
