What to do in Cozumel, and which half of the island to do it on

Your clock depends on how you got here

If you came on the ferry from Playa del Carmen, the crossing is thirty-five minutes and the last one back is the only fixed point in your day. Plan backwards from it and take the one before the one you think you need — the port closes for weather several times a year.

If you came on a cruise, your all-aboard time is earlier than you think and your pier may not be the one closest to town. Find out which of the piers you are at before booking anything, because the difference is a fifteen-minute drive.

And if you flew in, you have the island properly: mornings on the reef, afternoons anywhere, and no ferry to catch. It is the only version of Cozumel that is not a race.

The reef, which is why the island is famous

The reefs off the western shore are part of the Mesoamerican system and they are the reason divers have been coming here since Cousteau filmed them. Palancar, Colombia, Santa Rosa — drift dives along a wall, with visibility that is genuinely exceptional. Snorkelling works too, from a boat rather than from the shore.

It is a marine protected area and the rules are enforced: authorised operators, no touching anything, approved sunscreen or none at all. Sea state cancels trips and the decision is made by the port authority rather than by your operator, so build a day that survives being told no.

The east coast, which is not a beach day

The road across the island takes twenty minutes and puts you on a coast that looks like a different country: open Atlantic swell, empty sand, a handful of beach bars, and rip currents that kill people. Several of the beaches here have no safe swimming at all, permanently, and the signs saying so are accurate.

Go anyway. It is spectacular, it is the best drive on the island, and the bars along it are the nicest place to spend an afternoon in Cozumel. Just do not go to swim, and be aware that there are long stretches with no services, no phone signal and no fuel.

The rest of the island

Getting around

Hire something. Cozumel is bigger than it looks — the loop around the south is about sixty kilometers — and taxis for a full day of it cost more than a car or a scooter. Taxis are fine for town and for one trip to a specific beach club, and they are not metered, so agree the price first.

A word on scooters: the coastal road is fine and the cross-island road has fast traffic and sand on the bends. If you have not ridden one before, this is not the place to learn.

The ferry and the mainland

The passenger ferry leaves from Playa del Carmen, not from Cancún — this catches people out every week. A transfer from Cancún ends at the Playa del Carmen ferry pier and the crossing is separate. The Cancún–ferry route covers that leg; the Cozumel guide and the island airport cover the rest.

Traveler questions

Does the Cozumel ferry leave from Cancún?

No. It leaves from Playa del Carmen, about an hour south of Cancún by road.

How long is the crossing?

About thirty-five minutes to San Miguel, several times a day, weather permitting.

Can I swim on the east coast?

On most of it, no. The currents are genuinely dangerous and the warning signs mean it. Go for the drive and the bars.

Is San Gervasio worth it?

Yes, particularly if you have seen the coastal sites — it is shaded, quiet and a completely different kind of place.

Do I need to hire a car?

For a full day, yes. The island is bigger than it looks and taxi fares add up faster than a rental.
