Like ncchuck said, you really can't go wrong in Roatan, however the west side of the island has the superior diving over the south side in my opinion.... I have been an instructor in west end for many years and come rainy season we are forced to dive the south side..... Mary's place has a spectacular reef structure to it, but don't expect to see any fish!!! Micro creatures on the soft corals is all you'll get there, as well as 5 to 10 other dive operators on the same site... on cruise ship days you definitely want to try and avoid this site as AKR will drop 50 beginners on you!!! Most of the south side dives, don't expect to see many fish, however the wall formation makes it worth doing some dives.... Know lets get into west end, sting rays and eagle rays -- dive site;Tabyana's and Butchers bank,caves and canyons, hole in the wall, blue channel, canyon reef, and the spectacular Spooky channel Wrecks; El Aguila and the Odyssey, both 32mts, Reef structure; half moon bay wall, deep aquario, , a combination of reef, fish, and a deep water wreck(Josie J), in which only the Roatan Tec Team can reach, is at the point of the island or west end wall.... with the natural current moving south out the Cayman trench the current runs up over top of west end wall and will meet up with current moving west, in which is a dive site called Texas; another great site for fish and soft coral..... Schools of fish will accumulate at the point, and with schools of fish also bring the predators of the sea. The variety you get on this dive super succeeds any dive site in my opinion
In hindsight dive west end!!!!!
