We are going to Cozumel in a few weeks and I've been reading up but am in no way a professional on the subject. But the ruins on the island of Cozumel are not as fabulous as the ones on the mainland. Apparently from what I've read the "ruins" on the island are just worship "altars" when the women would come over from the mainland to honor a god. The ruins that were once the cities are on the mainland. Someone may know better but thats what I understood.And you may know that and be good with that. We haven't decided what to do yet. We really want to go to some of the larger ruins bt it requires a 6+ hour trek to/up the mainland.
