The Wakodahatchee Wetlands in Delray Beach, Florida are a man-made wetlands that is a water reclamation area for Palm Beach County Utilities.  There is a 3/4 mile boardwalk that provides good access for photographers and other nature watchers.  The highlight at Wako is probably the Great Blue Heron nests which are fairly close to the boardwalk and are easily observed.  Every year during nesting season there is a lineup of photographers that are watching the herons bring sticks back to the nest, mate, and then watch the baby herons grow up.  Other wildlife include gators of course, a lot of Purple Gallinules, and iguanas (an invasive species).  Wakodahatchee Wetlands is definitely one of my favorite places for nature photography in Florida.
