Pier to Virgin Cocoa
This pier became my favorite thing ever - it crossed the lagoon to a neighboring island (that I never actually went on), with all sorts of things passing beneath it at different tide levels. I think it was about a mile long and I walked it multiple times a day - it was like snorkeling without getting in the water, and not bad exercise when the weather and tides made it impossible to actually get in the water (unfortunately the case most of the week)
