Facilitating Amazon Adventures

Anglers considering the trip of a lifetime to South America's vast Amazon Basin should keep a couple of key numbers in mind - none of which directly address the astounding size of this amazing fishery.

First number is 500 - that's how many days renowned outdoor/travel writer Larry Larsen has spent fishing and exploring the Amazon. (It's actually a few more than 500, but we like round numbers.) The other key numerical expression comprises a range of 3-5. That's how many months of advance booking Larsen recommends in order to secure your preference in time slots and tour operators.
