Villa Blanca Wall is a sloping wall just offshore Cozumel with a ripping current. Before Hurricane Wilma, in 2005, it was peppered with huge sponges and gorgonians. Wilma pretty much wiped these out and covered everything with white sand. This is still a great dive and the changes to the reef don’t seem to have reduced the number of fish and critters, quite the opposite, for some reason there seem to be more.
Mary and I have been diving Cozumel for years and have both fond and frightful memories of Villa Blanca Wall. My most memorable dive there was with a young dive guide that, for some idiotic reason, decided to go against the current. Mind you Cozumel diving is pretty much all drift diving and to go against any strong current, much less one at Villa Blanca Wall, is insane.
