Cancún Airport Layover: Puerto Morelos by Bus
Part of the full Cancún Layover: Maya Ruins and Beach From CUN

Puerto Morelos, 27 kilometres south of Cancún International Airport, has a 1946 lighthouse left permanently leaning by a hurricane, a working fishing pier and a protected reef straight offshore, all of it a single coach ride from the terminals rather than the 40-minute run into the city.
The leaning lighthouse on Puerto Morelos’ shore
Hurricane Beulah came ashore here in 1967 and took the foundation out from under the town’s twenty-one-year-old lighthouse. The cement tower, painted white and blue, did not fall; it settled at an angle and stayed there. Attempts to bring it down all failed, so it was left alone, and a newer upright lighthouse went up behind it. The tilted one is now what the town is known for.

The pier beside it is the town’s working one. Small boats tie up along it, the day’s catch gets cleaned on the pilings where anyone walking past can watch, and the same boats run out to the reef that Puerto Morelos Reef National Park protects. It sits close enough to shore that a trip out is counted in hours, not a whole day, and reef snorkelling trips are sold ahead through a tours and activities platform, which matters here because they are not reliably walk-up.
Nine coaches a day run down to Puerto Morelos
The 210-peso fare buys a seat on a service that calls at Terminal 3, then Terminal 4, then Terminal 2 before it leaves the airport at all, which is why 27 kilometres take anywhere between 25 and 45 minutes. First departure is around 10:20am and the last around 6:20pm, about nine of them in the day, so a connection that lands at dawn or runs past dinner has nothing to catch.
Coming back is the part worth settling before you go. A direct coach from Puerto Morelos to the terminals is not always on the board, and the fallback routes you through the downtown terminal on a local bus and onto the airport coach from there, which is two tickets and a change. If that sounds like more than the time allows, the coach into Cancún’s own centre takes about the same half hour and opens up the Hotel Zone ruins and the downtown markets instead.
Terminals 2, 3 and 4 are separate buildings on a loop road and the shuttle between them runs on its own schedule, so whatever you are carrying waits for a bus with you rather than walking across.
The largest station on the Tren Maya stands across Highway 180
TEN Arquitectos put 34,745 square metres under a single folded canopy here, with five platforms and nine tracks beneath it and two lines of the network meeting in one place: one running west into Yucatán toward Izamal, the other south to Playa del Carmen. It opened on 15 December 2023 and is the biggest thing on the line.
Getting to it means crossing Federal Highway 180, which is why there is a shuttle from Terminals 2, 3 and 4 rather than a walkway. That service is run by the coach operator, takes about a quarter of an hour, and is timed to meet trains instead of running at a set interval, so the departure board inside the terminal is the thing to check, not a clock. For a connection with two or three hours in it and no appetite for a bus ride into town, walking the concourse of a station this size is a more interesting way to spend it than a departure lounge, and you can be back through security without having gambled on a return coach.
Frequently asked questions
What should I do during a layover near Cancún International Airport in Cancún?
With four to six free hours, the coach down to Puerto Morelos is the one real trip: 27 kilometres south, a leaning 1946 lighthouse on the shore, a working fishing pier, and a protected reef close enough offshore that boats run out to it and back in a morning. With less time than that, stay on the airport side and walk over to the Tren Maya station across Federal Highway 180, which is the largest on that network and reachable on a shuttle from Terminals 2, 3 and 4. Check the return coach before you commit to Puerto Morelos: the outbound service is thin and the way back is not always direct.
Can I reach Puerto Morelos and get back before my flight?
Only if the schedule lines up, and it needs checking rather than assuming. Roughly nine coaches a day leave the airport for Puerto Morelos, the first around 10:20am and the last around 6:20pm, so an early-morning or late-evening connection has no service at all. The return is the harder half: a direct coach back to the terminals is not always running, and the fallback is a local bus to the downtown terminal and the airport coach from there, which adds time and a change.
Is the shuttle between Cancún airport's terminals free?
Yes. Boarding points are marked outside each terminal, and the run between the two furthest apart takes about ten minutes. It is a separate service from the shuttle out to the train station, which is run by the coach operator, timed to meet trains rather than running at fixed intervals, and is not always free.
Does the Tren Maya go into Cancún city?
No. The only station is the one beside the airport, on the far side of Federal Highway 180, and no line runs into the city itself. Getting between the terminals and downtown Cancún is a road trip either way, on a coach that takes about half an hour.
