Considering the Secreto in Isla Mujeres?

Car ferry to Isla Mujeres by Pat&ZoAnn
If you have a car already, you can take it to Isla Mujeres on the car ferry which runs from Punta Sam (about 3 miles north of Cancun). The cost at the time of writing this tip is about $15.00 US for car and driver, plus $2.00 US per passenger. There really is no need for a car there, but if you have already renterd one, and Isla is just one stop on your journey, you can do it.
