Puerto Juárez Layover: Cancún to Isla Mujeres
Part of the full Cancún Layover: Maya Ruins and Beach From CUN

Puerto Juárez, at the north end of Cancún, is fifteen minutes by boat from Playa Norte on Isla Mujeres, and the 12.5-metre Maya pyramid at El Meco stands two and a half kilometres up the coast road from the same quay.
Playa Norte’s shallow water at the top of Isla Mujeres
Isla Mujeres is eight kilometres long and barely six hundred metres across at its widest, and the beach at the northern end is the one most people cross for. The water at Playa Norte stays waist-deep a long way out, which is why the beach reads as a swimming pool in aerial photographs. It is also the closest beach to where the boats tie up, so it works for a few hours in a way the rest of the island does not.

The crossing is fifteen minutes and 78 pesos each way
Boats leave the quay roughly every half hour through the main part of the day and drop to around hourly into the evening, and most of them have an open upper deck worth climbing to rather than sitting in the air conditioning below. Round-trip tickets can be bought ahead through a tours and activities platform, which mostly saves queueing twice.
Published times for the last boat back off the island disagree between sources and move with the season, so the number to trust is the one on the board at the ticket window on the day, checked before you cross rather than after.
El Castillo, the stepped pyramid at El Meco
Kilometre 2.7 of the road running north from Puerto Juárez towards Punta Sam is where El Meco sits, a Maya port settlement whose main structure, El Castillo, still stands 12.5 metres high. That makes it the tallest thing left standing on this part of the coast, taller than either of the sites in the Hotel Zone, and the top of it looks back across the water at Cancún.

Admission is 75 pesos, the gates open at 8am every day of the week, and Mexican nationals with identification get in free on Sundays. It is a quieter site than the ones further south, partly because most people arriving at this quay are looking at the water rather than the road behind them. If the day is going to include only one of the two, the island is the better use of a long gap and the ruin is the better use of a short one; the full Cancún itinerary covers the Hotel Zone sites instead.
No single ride connects the island to the airport
Getting from this quay to Cancún International Airport (CUN) takes two legs and no direct service exists: a southbound city bus down Avenida Tulum to the downtown coach terminal, fifteen to twenty minutes, then an ADO coach out to the airport for around 140 pesos and about half an hour on the road. Allow an hour and a half from stepping off the boat, more if the last sailing you plan to catch is an evening one.
The boat’s own baggage rule is worth knowing before you carry anything across: each ticket covers one piece up to 25 kilos whose three dimensions add up to no more than 142 centimetres, so a full-size suitcase is not guaranteed a place on board.
Frequently asked questions
What should I do during a layover near Puerto Juárez Ferry Terminal in Cancún?
Five to seven free hours is enough to cross to Isla Mujeres and come back with time to sit down. Boats run the fifteen minutes to the island for 78 pesos each way, and Playa Norte, the shallow white-sand beach at the northern tip, is the closest thing to the dock on the other side. On the mainland, the El Meco archaeological site is two and a half kilometres up the coast road, where El Castillo stands 12.5 metres high for 75 pesos. With less than five hours, do one or the other rather than both, and check the evening sailing times before you cross.
Which Cancún ferry terminal is cheapest for Isla Mujeres?
Puerto Juárez. It is the mainland terminal closest to downtown Cancún and the one running the most sailings, and the fare from here is lower than from the piers inside the Hotel Zone, which charge noticeably more for the same island and the same water. The trade-off is that the Hotel Zone piers are easier to reach if you are already staying on the beach strip, while this quay is a short city-bus ride north of the centre.
What does El Meco cost and when is it open?
General admission is 75 pesos, and the site opens every day from 8am, with last entry in the middle of the afternoon. Mexican nationals with identification get in free on Sundays. It sits at kilometre 2.7 of the Puerto Juárez to Punta Sam road, so it is a short ride north rather than a walk from the dock.
How do I get to Puerto Juárez from downtown Cancún?
A northbound city bus from Avenida Tulum, 15 to 20 minutes, for a fare in single-digit pesos paid to the driver in cash. The ones that go all the way carry Puerto Juárez or the ferry operator's name across the windshield, so check the sign rather than the route number, and say the destination to the driver when you board.
