I would like information on this as well. I was wondering if it is still available because when I tried to book through carnvial's website it was not an option for me. Has anyone else has this problem? Maybe I will just snorkel on my own.

If you want to snorkel on your own for very little cost, take a taxi to Dzul Ha where it is free to snorkel if you have your own gear. Taxi driver will know where to take you. There is a place for food and drinks and for renting gear if you do not own your own.
