Great video! I was able to do one dive in the cenotes there about 7 years ago and I really want to do some more! I have not made it a priority to go back because I would like to start getting cave diving certifications so I can enjoy more of what cenotes have to offer!
The land owners are tightening up now, being forced into tougher measures by the authorities, so come sites are off the table. We've pretty much lost Sac Aktun and now Grand Cenote is off the table for Open Water divers, with a minimum cert of Cavern Diver or above.
That's good to know thanks!
