I am staking out my next dive trip and am considering making my first trip to Cozumel. I have always heard the diving in Cozumel is great. However, most of the videos I have seen recently (mainly ones referencing Aldora) make me wonder about the quality of Cozumel's reefs. Most of what I have seen is primarily algae, rock (very cool structures) and sand. There are some patches with a few soft corals and sponges, but they are the minority. Hard corals are almost completely absent. Is the draw of Cozumel diving more based on temperature and visibility, or perhaps large animals, and less on the reefs? I am trying to target the best reefs in the Caribbean and am looking for input.
