I have been diving from Playa del Carmen for tha last 3 years making 3-4 trips /year. You can't beat the convience of flying into Cancun and diving the same day from Playa! The cenotes dives are certainly the most unique dives on the Yucatan ! Not everyone finds the cenotes environment to their liking but you should try them at least once. There are about 10 cenotes that are regularly dived and they each have very unique personalities. Gran Cenote near Tulum is probably one of the best to initially try as it has some wide open areas as well as cavern areas. One can dive many Playa- side sites in the ocean as well that are quite good. Tortuga is always worth it for the turtles ( usually 6-10 turtles per dive). Other sites such as the "Arches" have healthy reefs and rival Cozumel. From Playa , Cozumel is only a 45-60 minute boat ride with Playa dive operators. I have had great diving (cenotes, playa ocean, cozumel, and night diving) with Tank-Ha Dive Center which is located on the main pedestrian street "5th Ave" (www.tankha.com). My next trip also in June will include the snorkeling trip to Holbox in search of whale sharks. I have of Playa dive pix at www.meinig.com which will give you some idea as to the diving and photography possiblilities...Rick Meinig

FWIW Mayakoba is a bit North of Playa I think.
Anyway the Cenotes are fun to try, you can go with Hidden Worlds or other general operators or can hire a private guide, I have done both.
Across the way from Playa is Cozumel and there are many great sites there if you want to go across early one day.
There are some areas between Cancun and Tulum on the Playa side which has diving, some areas better than others depending on how well they are protected. Some sections are dying out, I have seen it gone down hill alot unfortunately as the "Riviera Maya" has grown.
Off Playa there is one site called Tortugas which is sort of like a retirement home for turtles, huge big old ones just lying there. Many people like that site, though I did not care for it much, though there was alot of surge and circular currents the day I went. Very strange.
Isla Muejeres (from other ports in the area about 40 minutes drive) and 15 minute ferry ride has some nice sites and home of the sleeping shark cave, though I heard that they are not as many as there used to be.
