4 /5 Mark: A small lesser known park with a boardwalk that runs most of the way on out to Riveria Canal on some of Key Wests most isolated land; the old salt flats behind the airport. Some interesting history here, if you want to look into it. Excellent for birding, you can find whole blogs about the birds here, though I wouldnt visit alone for its general remoteness and evidence of elicit activity.
