This was on the island. There are plenty of easily accessible cenotes on Coz...and others that are far from being easily accessible. The one we did most of our training in we drove right up to the entrance.
Contact German Yanez if you are looking for a guided trip. He knows the cenotes on Coz like the back of his hand. He's also and instructor if you want a cave diving cert. Here's his website: Yucatech Expeditions.
German also was...don't know if he still is...the island's diving safety officer. You won't find a more capable guide.
Thanx, will look him up when we go down there
