Hi Berckerman,
Last summer I dived in Roatan, I cruised around the island and visited few diving centers/resorts. I could just agree with Abraham, the West End and West bay are nice places to go with a lot of great diving.
There are a lot of nice spots to dive on the North side, particularly, The Blue Channel and El Aguila, a wreck at 70 feet with three huge groupers squatting the place (my preferred).
Anthony’s key is well equipped, several boats, nice amenities but a little remote. If you want to dive, dive and dive and get to bed at 21:00 that is the place.
I got two friends who dove on south side at Fantasy Island and their feedback is good.
I went to Las Rocas, it is a small place in West Beach. The boat accepts a max of 8 divers and the divemasters were very professional and flexible. Next time, I will stay at Captain Morgan (my wife wants a big-nice pool) but probably dive with Las Rocas or try Bananarama.
This summer, for me, it will be Club Med in Bahamas!
Have a nice diving summer!!!
