Like Driftwood mentioned.... Beaches south of tulum are the absolute best, El Pariasio is awesome. For snorkling... Right south of Akumal, on the coast road about 1/2 mile down is Half moon bay, best snorkeling in the region IMHO. Also...another 1/4 mile down from there, a more secluded water park, Yal Ku. Get there at 7am, fantastic snorkling until the droves arrive around 10, plus it only costs $8.
Retsaurants in playa....Im a simple guy, gimme goooood tacos and Im happy
, which means Carboncitas. Zenzies at night is a nice spot for 2
If you do Coba....rent a car for the day. I left at 6:30, got there at 5 to 8 (opened at 8). First one in the park, rented my bike, and zipped thru in a couple hours. Left right when all the tour buses arrived at 10
It's awesome when you have the jungle to yourself.... it just felt more...real I guess without all the bus loads of peeps...LOL.
I've yet to go to Chitzen Itza...thats a lot of road time...
Another lil nugget... I like researching, the Loco gringo website has great aerial shots of the whole coast that come in quite handy
Have a great time!!!
