CR is supposed to be great for tarpon in turbid (read: muddy) water, and some excellent permit fishing in spots. I don't know what else they've got, probably some bones, too. Plenty of English-speaking guides and lodge outfitters down there, that's for sure! I know a lot of folks who go to CR to fly fish for tarpon and permit, but a bunch who also fly fish offshore for billfish down there. That's supposedly the thing CR is really tops for.
