My wife and I went diving there last year. The diving isnt that great but there are some cool wrecks.
The one dive that is a must (in my opinion) is the Antilla. It is a German freighter that was sunk during WWII by the dutch marines. You cant really penetrate the wreck anymore since the hurricane tore it up a few years back making it pretty unstable, but it is a cool wreck that hasn't been "sterilized" like most sunken ship/artificial reef wrecks. So, you can still see some of the stuff that remains from the day it was sunk except for whatever valuables that were looted after the war ended haha.
