Any good diving around Tulum?

[DetectorGuy]

I am going to Tulum Mexico for 11 days on Friday and I plan on getting in some cenote dives in. Does anyone have any "must dive" cenotes in that area? I think I will do some reef dives as well. I don't think there are any wrecks in the immediate area around Tulum but if anyone knows of any, I would like to know about them. At the end of the trip we are going to be in the North point of Cancun for a couple days and I wouldn't mind diving that C-58 wreck. A couple years ago I dove the C-56 wreck near Puerto Morelos but I had a crappy camera then and the pics were terrible. That new underwater museum near Isla Mujeres would be kinda neat too, but I don't think they have much of it done yet...
