At cancun, I visited one of the beaches there. It is called La Isla Mujeres. Although, the time of the year I visited was not one of the highly subscribed seasons, because the beach has lots of seaweeds during this time. Notwithstanding, I still managed to have some fun. It was around 45 minutes drive from Cancun town.
There is a ferry that transports people from the main town across the sea to La Isla Mujeres. The commonest ferry is called Ultramar. s
In case, you are planning a vacation, you can have a good time in Mexico-Cancun.
