Diving the Blue Heron Bridge is a macro photographer’s dream! There are seahorses, octopus, pipefish, frogfish, batfish, nudibranchs and other rare and exotic species of sea life you won’t find out on the reef. With the intercoastal's delicate ecosystem, it is ideal for these species.
But don’t rule out the rare sightings of manatees, spotted eagle rays, manta rays, nurse sharks, green sea turtles, or Goliath Grouper that locals have encountered at the Blue Heron Bridge. These encounters are frequent, so you're pretty much guaranteed to see something amazing. It should be noted that divers and snorkelers should NOT touch or disrupt the marine life. This can be dangerous to the diver as well as the wildlife.

The park is open for diving after sunrise and before sunset. Be aware of the posted times for the public to use the park, anyone in the park past 10 pm may get a ticket. Individuals cannot dive at the park at night without a permit. Force-E's FREE Blue Heron Bridge night dives are held every 2 weeks. Force-E has a permit with the park to allow divers in after posted hours, but you must sign in with Force-E before you go and get a parking permit.
You have to dive BHB during slack high tide. Since this is a shallow dive, you can spend up to two hours underwater. Aim to get in the water two hours before high tide, so the current (and visibility) stays good. Make sure you check the tide tables before you go.
