Easy dives are Buccaneer, Green House, Scott's, Radar, Public beach, and the little mini wall east of the freight dock. Short swims in calm water. Someone has put rocks per Bonaire to locate the spots. Actually any place you choose you will find a nice spot. The beach line is crown property and open to anyone. Park where permissible and bring a flag. There is a Brac Shore Dive Facebook page that has some info. The south east walls are spectacular and IMO are the best in the Caymans, rough entry and an athletic exit over iron shore are required. It is worth the trouble. Northeast dives at Burts Boulders, and further east are always fun and usually something interesting is found. It's and easy entry from a cut out after the boat launch(Soot Bay). Weather permitting of course.
As always bring the hiking gear. The cliffs behind Spot Bay are some of the prettiest rock climbs in the world. With zero crime, safe diving and a chamber, Brac is best. They have endemic birds, reptiles and plants found nowhere else in the world. I still like the snorkeling around the docks at west end in the shallows, everything from baby turtles and octopus to rays and sharks. There are even supposed to be seahorses but I have yet to find one. Everybody is friendly, so ask if you have questions.
Stay safe and hopefully the winds stay down so you can dive the whole island. Cheers
