OMG, YES, YES and YES!!!! Cozumel has AWESOME diving!! The "Wall" is awesome. It is just incredible, a beautiful, blue, huge 400 foot drop. A great place to drift dive, and it is not terribly fast or scary, so if you haven't done it before, this is a good place to do it. The Cenotes are absolutely fan-freaking-tastic. If you can, don't miss these!! Just go anywhere and everywhere you can, then go back!
