Diving conditions
The best time for diving the Blue Heron Bridge is half an hour before or after slack high tide. At this time, clear water from the Atlantic Ocean allows visibility up to 30 metres/100 feet. It is extremely important to review the tide tables, and plan your dives accordingly. Diving outside of this window puts you at risk of diving in heavy currents as the water transitions out of the ICW.
You will find the clearest water under the east and west bridges but if you are not careful, you can stir up the thin layer of sediment on the bottom, resulting in poor visibility. Another tip is to be prepared and aware of other divers around you. The Blue Heron Bridge was voted the top dive site in the nation in 2013 and that reputation, accompanied by very few shore diving locations in the area, brings in a lot of other divers. Since the average depth of your dive will be in the 3 metre/10 foot range, a typical dive at this location can last from 60 – 90 minutes, depending on air consumption rates.
Safety tips
Safety is always a key issue when diving. The tidal flow around the Blue Heron Bridge area can be strong when it is not high slack tide. Scuba divers are required to, and should always, use dive flags, otherwise there is a chance of being injured or fined. A boat channel runs about 30 meters/100 feet parallel to the shore and under the center of the bridge. Use caution and stay clear of this area.
The Phil Foster Park is open from sunrise to sunset. Diving is not allowed at any other time unless by a special permit from the county. Several dive shops offer guided night diving excursions and private tours. The park has on-site restrooms, picnic tables and grills as well as plenty of parking and space for pre-dive setup. Tanks, weights and other gear are available for rent or purchase at local dive shops located near the Blue Heron Bridge, and all over South Florida.
The diverse ecosystem, easy accessibility and all-weather diving conditions at the Blue Heron Bridge have earned it a top spot on the list of the best dive sites in the world. So this inconspicuous public park is actually a once-in-a-lifetime scuba diving destination! Enjoy and happy diving!
