Leg 1: airport to the pier
Puerto Juárez sits north of the city of Cancun, so the drive does not take Highway 307 into the Riviera Maya: it crosses the city. What slows it down is city traffic, not the corridor.
It is an ordinary private transfer, except that it ends at a terminal rather than a hotel door. The rate, the times and what is included are on that route’s page.
Leg 2: the ferry
You buy the ticket at the terminal, directly from the ferry operator, and it is not included in any rate of ours: we do not sell ferries and we take no commission on them. They run through the day; timetables and fares are published by each operator and they change, so we do not reproduce them here — check them on the day you arrive.
The vehicle does not cross with you. If you are travelling with large suitcases, plan on taking them off at the pier and onto the ferry.
Do not mix up the two piers
There are two different departure points for Isla Mujeres in Cancun: Puerto Juárez, north of the city, and a pier in the Hotel Zone. They are not the same, they do not cost the same from the airport, and they do not land at the same point on the island.
Our transfer on this route goes to Puerto Juárez. If your plan leaves from the other one, tell us when you book: it is a different destination and a different rate, and it is better sorted before you pay than discovered at the wrong pier.
How to plan the total time
Add three things, not two: immigration and baggage at CUN, the drive to the pier, and the crossing plus the wait for the ferry. Our range covers only the middle one; the other two are not ours to control.
If you are flying home, plan the return with margin. Cancellation with us is free up to 24 hours before, so booking early ties you to nothing.
