Because Isla Mujeres is an Island, the only way to get there is by boat. There is a Ferry service that connects the Island to multiple locations, the primary one being Puerto Juárez for those coming from the Cancun International airport (CUN).
For more information, please visit their website: Ultramar Ferry
Routes and departures: Departures (Look for 1.-Cancún, Puerto <–> Juárez Isla Mujeres)
**Depart every 30 mins during the day.**
**Fares are in pesos**
There are multiple companies that will provide transportation from the airport to the Ferry. There are two in particular that we recommend. Both are reasonably priced. We personally used them and always had a good service. Book in advance using their websites.
