Blue Heron Bridge

Riviera Beach · Florida · United States

Blue Heron Bridge sits in the unlikely setting of Phil Foster Park in Riviera Beach, Florida, where a concrete bridge over the Lake Worth Lagoon inlet has become what many consider the best shore dive in North America. The site's appeal is simple to state and difficult to believe until you experience it: in water barely deep enough to submerge a basketball hoop, the sandy rubble and bridge pilings harbor a concentration of rare and unusual marine life that rivals famous muck diving destinations halfway around the world. I entered the water at slack high tide on a warm March morning, walking in from the beach in the park's designated diving area. The entry is as easy as diving gets -- a gentle sand slope into clear, warm water, with the bridge pilings visible immediately to the north. Visibility was about ten meters, the morning sun lighting up the sandy bottom and the scattered rubble that forms the basis of the ecosystem. The first seahorse appeared within five minutes, a lined seahorse wrapped around a piece of rope at three meters depth, its prehensile tail curled in the classic S-shape, its body swaying gently in the mild tidal current. These delicate animals are Blue Heron Bridge's signature residents, and local guides track their locations daily. On this dive I would find four more, each clinging to different structures in the rubble field. The diversity across such a small, shallow area is genuinely remarkable. A painted frogfish sat motionless on a sponge-encrusted rock, its body a perfect color match for its perch. Spotted batfish crouched on the sand, their oversized pectoral fins spread like wings. Octopus flowed between hiding spots, their chromatophores rippling through color changes as they moved. Flying gurnards spread their enormous blue-spotted pectoral fins in threat displays when approached too closely, creating one of the most photogenic moments in underwater macro photography.
