Okay, so Dean's Blue Hole in Nassau & New Providence. It's a proper blue hole, a big sinkhole plunging down. While the full depth is for freedivers doing the Vertical Blue competition, the upper section offers some interesting wall diving. We've explored down to about 35 meters there, finding a good mix of turtlegrass and manatee grass along the edges, and sometimes spotting Milk Conchs or Deltoid Rock Shells. The visibility is usually excellent, making it a good spot for divers comfortable with depth and a bit of open water feeling.
