Blue Heron Bridge

Riviera Beach, Florida, United States

Widely called the muck-diving capital of the world — a protected shore dive under the Blue Heron Blvd bridge at Phil Foster Park in Riviera Beach. Max 6 m depth, divable only around slack high tide (±30 min) when clean Atlantic water fills the basin. Macro subjects include seahorses, frogfish, batfish, pipefish, flying gurnards, star gazers, octopus, and nudibranchs. Easy walk-in entry, sand and rubble bottom, and the world's most unlikely pelagic and manatee sightings. Bring a small reel to navigate back against a soft flood tide.
