Hey DiveGirl55! YES! There are definitely Cenotes on Cozumel, I have been racking my brain trying to remember what outfit i was with when i was there,because when i usually Cenote dive i go to the Yucatan Peninsula’s mainland because they are so many more Cenotes. But to your question, yes there are Cenotes on Cozumel. When i ask my buddy who we Cenote dived with on Cozumel i will hit you back.Not all dive operators on Cozumel do Cenote dives, or at least not the last time i was there in Nov. 2007
