For an hour either side of high tide, the water under the bridge turns clear and calm, and the rubble reef comes alive with seahorses, frogfish, octopus and rays. Walk in from the beach and swim a few hundred feet.
Your reef is an artificial trail of limestone boulders and reef modules, about two acres in shallow water, with seagrass and sand around it. This is a macro site. Most of the reward is small animals tucked into rubble and onto buoy lines and rope, so swim slowly and look closely. Larger visitors include spotted eagle rays, stingrays and barracuda. Visibility swings from poor to excellent with the tide.
A marked reef trail about 150 ft off the beach. Local guides describe it as roughly 800 ft long.
Look near buoy anchors, ropes and floating sargassum. Look, but do not touch.
The park page lists octopus and squid as regular sightings. Check crevices in the rock.
Visitor reports mention polka-dot batfish, spotted rays and stingrays on the sand and reef edge.
Tiny fish that wrap their tails around seagrass and sponges. Patient snorkelers find them on calm, shallow Florida sites.
Hippocampus
A lumpy, camouflaged fish that walks on its fins and lures prey with a fishing-rod spine. Blue Heron Bridge is famous for them.
Antennariidae
A master of disguise that changes color and texture to match the reef. Look for a pile of shells outside a hole, which often marks its den.
Octopus cyanea
The Atlantic eagle ray, dark with white spots and a pointed snout. In Florida it glides over sand and seagrass near reefs, often in pairs or small groups.
Guardian rule: Give it room and never chase it.
Aetobatus narinari
A diamond-shaped ray that buries itself in sand with only its eyes showing. Common on Florida reefs and sandy flats.
Spotting tip: Look for a flat outline and two eyes poking out of the sand.
Guardian rule: Shuffle your feet when wading so rays can move away before you step on them.
Hypanus americanus
A long, silver predator that hangs motionless near the surface and watches snorkelers with curiosity. It looks fierce but rarely bothers people.
Guardian rule: Take off shiny jewelry, which can look like a fish flash.
Sphyraena barracuda
Colorful grazers with fused, beak-like teeth. You can hear them crunch on coral rock, and much of the white sand on tropical beaches passes through them.
Scaridae
A small yellow and silver damselfish with five black bars. Bold and curious, it is often the first fish to swim up to you on a Florida reef.

Tide beats season here. The warm months are most comfortable, but any month works if high tide falls in daylight and winds are light.
Be in the water about an hour before high tide. Weekday mornings are quiet.
High slack tide. Enter 45 to 60 minutes before high. Slack follows about 30 minutes after high and gives the best visibility. When the current turns, clarity falls.

Yes if you time the tide and bring a dive flag. The entry is a gentle sandy beach and a lifeguard covers the swimming area, but the trail sits beside an active boat channel with a strong current. Check the tide chart, snorkel with a buddy and never swim south of the trail.
Swim level: Comfortable swimmer
Phil Foster Memorial Park is at 900 E Blue Heron Blvd, Riviera Beach, on the bridge to Singer Island. Walk in from the beach.
Use the park lots past the boat ramp and restrooms, not near the boat channel. Lots fill early on summer weekends. The beach closes at sunset, so be out of the water before then.
Enter from the sandy beach beside the bridge and swim out to the marked trail. Swimming from docks, piers, bulkheads and boat ramps is prohibited. Diving and snorkeling outside the guarded area is allowed sunrise to sunset.
The county park page lists no fee for regular parking. Only boat trailer parking needs a $15 daily permit. Confirm on the park page.

Phil Foster Memorial Park is the county park at the foot of the Blue Heron Bridge. It has a beach, boat ramps, a fishing pier, restrooms and showers. The artificial snorkel trail covers about two acres of boulders and reef modules. Diving and snorkeling outside the guarded swimming area are allowed from sunrise to sunset.
The trail sits beside an active navigation channel. Fly a dive flag, stay with your buddy and keep north of the trail. Boaters must slow and keep 100 ft from a flag in channels and inlets, but do not rely on it alone. Surface and look up often.
Phil Foster Park is a county park and the trail lies beside a navigation channel, so the rules are practical.
Florida law requires a divers-down flag or buoy when a diver, including a snorkeler, is in the water. Stay within 100 ft of it in inlets and channels and within 300 ft elsewhere. Boats must keep clear by the same distances. Official rule
Collecting or possessing tropical fish and ornamental marine plants is prohibited in the park. Official rule
Do not swim south of the snorkel trail or in the boat channel. Swimming from docks, piers and boat ramps is prohibited. Official rule
Seahorses and frogfish are delicate. Handling stresses them and can injure them. Keep fins off the bottom to protect the rubble reef.

High slack tide. Enter the water about 45 to 60 minutes before high tide. Slack comes shortly after high, when the current is weakest and visibility is best. Once the current turns, clarity drops. Always check a current tide chart.

It can be, in calm conditions at slack tide. The water is shallow and the entry is gentle. The risks are boat traffic and current. Beginners should go on a guided trip or with an experienced buddy and use a flag.
