Florida Keys

The Keys are the saltwater fishing capital of the world — period. The shallow flats hold permit, bonefish, and tarpon (the "grand slam" of fly fishing), while offshore reefs and wrecks produce sailfish, mahi-mahi, and yellowfin tuna. Islamorada calls itself the "Sport Fishing Capital of the World," and with more IGFA world records than any other destination, it's not exaggerating.
