Two divers with us in Oct 2003 for their first trip to Bonaire felt that out of 16 dives during the week, Invisibles was the best. Entry/exit is not that difficult and navigation is easy due to the sand chute that goes down the wall. It allows you to terrain associate from and to the entry and exit points. A coral island can be found down and out from the wall around 100 ft. This is the only place I have seen this particular type of formation on Bonaire. I highly recommend this dive keeping in mind the really good stuff is fairly deep.
