I just returned from a very nice trip to Little Cayman. My wife and I stayed nine nights at Little Cayman Beach Resort, where we have been twice before. Little Cayman has my favorite Caribbean diving. The Bloody Bay Wall has wonderful healthy reefs, and incredible topography.
Here are some pics from the trip, a few macro and a few wide angle to give a sense of what it was like.
and here is the link to the whole set: Flickr set of Little Cayman pics
