A group of 6 will be visiting Playa del Carmen and Tulum next winter. Any recommendations on the best snorkeling from Playa south? My wife remembers good snorkeling at Xcaret, not as good at Xel-Ha or Yakul. Being a scuba diver I was never that impressed with any of the snorkeling, but this trip will be scuba-free so any advice will be appreciated. We have been going to the Riviera Maya since the early '90s and have seen the rampant (over)development of the area, but it is still hard to beat for warm weather, beautiful blue water and good value for a winter vacation.
