I am an experienced diver with over 17 years experience and to be honest, at first, I was quite hesistant to dive beneath a bridge in the middle of the Intercostal. However, my reluctance was to my own detriment, as the Blue Heron Bridge has become one of my favorite shallow water dives, and is especially convienent and offers exceptional dive conditions even when the ocean is rough. The bridge showcases a greater diversity of marine life in a shorter area than many east coast ocean dives. You are likely to see spotted stingrays, flying gunards, pufferfish, seahorses, lobster, arrow crabs, parrotfish, horseshoe crabs, pillow starfish, and even a stray manatee. This is only a sampling of the marine life you are likely to come across in only 12-15 feet of water. Other noteworthy advantages of this location are easy entrance and exit, as the entry point is directly underneath the bridge and the parking lot is only feet away. In addition, parking is free.
That being said, no review would be complete without mentioning at least some of the downsides of Blue Heron Bridge, however, even these are far outweighed by the positives. Sometimes the location is swarming with divers, mostly open water 1 classes, and it is dfficult to separate from them. The best way to find seclusion is to dive near the old part of the bridge to the right of the entry point, as most classes are to the left. Also, because this is an intercoastal waterway dive, tide conditions msut be adhered to for best visibility and low current. Best time to get wet and start your dive is 1 hour before high tide, so check the tide schedule online before you go out there. This means that sometime you will have to dive at 6:45am and other days it might not be until 11am. The last ocncern is to make sure oyu do not stray into the boat channel as this is not only illegal but highly dangerous. You will know the boundary of the channel as it is a row of closely spaced concrete columns. Always use a dive flag.
Overall the Blue Heron Bridge offers a relaxing dive teaming with life. Make sure to look inside the columns of the bridge to find even more fish and growth. Always a different experience no matter how many time you dive this site. Great backdrop of Singer Island and Peanut Island too!!
