Margaritas, mega-resorts, Mayan ruins, this is the real Cancún. In the 1970s Mexico's ambitious tourism planners decided to outdo Acapulco with a brand new, world-class resort in the Yucatán Peninsula. The place they chose was a deserted sand spit offshore from the little fishing village of Puerto Juárez. Its name was Cancún.In the last two decades Cancún has grown from a little jungle village into one of the world's best-known holiday resorts. The Mexican government sunk vast sums into landscaping and infrastructure, yielding straight, well-paved roads, drinkable tap water and great swaths of sandy beach.
