I am visiting Tulum over Christmas, at Cabanas Copal. Wondering if there is a gay beach area around there/Tulum? Is there a gay bar in the area?
I don't know of any gay specific beaches or bars in Tulum, but that doesn't mean you are unwelcome. I saw many gay couples on our trip in August.
There may be beaches and bars in Playa - in fact there is an undisclosed gay beach north of PDC and south of Xcalacocco. I can't tell you exactly where it is - you just have to walk the beach and you'll know it when you see it (as I did unknowingly, but then confirmed by my hairdresser after I returned home).
Yes, the gay scene is in Playa del Carmen or Cancun.
But if you want to create a gay beach in Tulum for new years eve, let me know.
or try "gay tulum" with google... there are some informations there.
