The Catedral de Cancun is meant to serve to local Mexican Catholic population of Cancun city, not really the tourist hotel strip area of Cancun. We traveled to the Catedral in our rental car after visiting the near by Mercado 28. The Catedral was not at all what we expected, as its very modern and stark in design. It is interesting that it is a completely open air Catedral. I was curious wondering how hot the services must get at times, although there was large industrial fans placed about. I would say its worth a visit if you're Catholic and into seeing the local version, but otherwise as any other casual tourist, I would not go out of my way to see it. read more
