My wife and I stayed at Blackbird resort on Blackbird Cay lasy year and can't say enough. Dive was great, excellent food Great cabins on the beach and great staff. Very clean, professional, and relaxing week. but after being out to the atolls a couple of times, it looks like any of the places out there would offer you excellent diving, plusthe blue hole preserve, where you get to see blue footed boobies in the wild up close and personal. While we were there we dove with a newly married couple who had gotten married down there on the mainland, and spent there honeymoon next to an underground river. it was all done quit nicelt they said. I can get you the name of that place. the only bad thing that happened to them that at one particular resort in the jungle, the owner had a pet monkey who was a junkie for Coca Cola. the bride didn't give hers up when the monkey asked for at , and she got bitten pretty well.
What ever you do, don't try to dive directly from Belize city. You really have to go out to the atolls for the good diving.
