There is a lot of diving here in the Ft. Lauderdale area, and the best shore diving in the state! The first reef line is only a hundred yards or so off shore, an easy surface swim....Also, there are a bunch of beach divers here on the board, so finding a buddy usually isn't too difficult.
There is also a lot of boat diving. Additionally, the keys are an hour and a half away, venice is 3 hours and the springs 3+.
Now, as far as maps of dive sites and all. For beach diving there is a book you can buy at most dive shops that gives very good descriptions of beach and snorkeling sites from Jupiter to Hollywood.
SOMEDAY our conchdivers site will be up (and yes, I am one of the lazy webmasters...) and we hope to include all kinds of dive info, including maps and such...
Let us know if and when you are arriving so we can dive!
