This is part of a half-mile long boardwalk through the mangroves of central Florida at the Crowley Natural and Cultural History Preserve. I don't know how they passed through mangroves on foot back in the day, but without this boardwalk it seems to be impassable. The walk is pleasant and shaded with few distractions and at the end a wooden tower overlooking a river and floodplain. Along the way you see native plants, animals and birds and get a small glimpse of what the land was like in years past, back when they had no boardwalk.
