Dive 2 hours before high slack tide (2 hours is all you get). BEST TALK TO THE LOCALS. VERY DANGEROUS PLACE. If it's done during tarpoon season, if the tide don't get you, the great whites will! Never actually dove it, because I didn't know the tide tables, and it's better I didn't!  School of over 300 Great Whites off shore (found out later from the dive shop).  It's not as great as when the dock was used years ago, but fish still school there. It's about 40' deep, and not for the beginner. -- Mad Marl

Go to the end of the island of Boca Grande. Park in public parking. Follow the beach around the point. Find Phosphate Dock (you can't miss it!)

Phosphate Dock

Dove this site by boat and shore many time.  Conducted Goliath Groper Counts there for Sea Grant in June, many times.  Those were during Tarpon time.  Could be epic or crap depending on the conditions.  Slack tide is the time to go.
