The bridge at Bahia Honda State Park on Bahia Honda Key is a shallow (8 - 11 feet) but a good dive. It's almost too shallow for scuba but the viz is not quite good enough for prime snorkeling. Pull a dive flag and stay out of the boat channels. There's are lots of fish in numbers and variety, crabs and lobster and small nurse sharks eating the crabs and lobster. Look closely around the bridge pilings and there is grass and soft corals on the bottom. Bahia State Park is on Hwy 1 in the Florida Keys. Exit into the park and follow the park roads around to the base of the bridge.
