The best beach in Cancun has the following features:
Powder White-Sand Beach. The hurricane Wilma (2006) it did not blow away the sand of this side of Cancun so preserve the original one.
Crystal clear turquoise water. Here you can find the best blue colors.
Calm sea. This side of Cancun has calm waters due to the geography of Cancun’s hotel zone.
Best View. On week ends you can appreciate yachts parking a few yards from this beach and you can appreciate “isla Mujeres” in the horizon.
