The shared whale shark day
Our 11- and 13-year-olds swam, and the non-swimmer in the family managed with a patient guide. A bumpy ride out, so take seasickness medicine.

Isla Mujeres Snorkeling with Whale Sharks, from the Island or Cancún
Whale sharks, mid-May to mid-SepIsland or Cancún pickupPlus US$10 fee, cashLunch included
The biggest fish in the sea, a few metres from your mask. Ten guests at most ride out past Isla Mujeres to where the whale sharks feed. You swim beside them two at a time with your guide, and you get two turns each. On the way back you stop in the shallows for lunch made on board. It runs only in the summer season.

One of the most-reviewed whale shark days you can book.
From the Black Pearl dock or your Cancún hotel
If you are staying on Isla Mujeres, you meet at the Black Pearl dock, Abasolo 13, downtown, behind the Perla Negra store. If you are staying on the mainland, the fare includes a pickup from your hotel in Cancún, the Riviera Maya or Playa del Carmen. The driver takes you to the Punta Sam ferry terminal, where the boat meets you. Michael H. was collected from Playa Mujeres and found it easy.
Transport around Isla Mujeres itself is not in the fare, so from a hotel on the island you make your own way to the dock. There is a short restroom stop before the boat leaves, and then no more until you are back. How Punta Sam and the ferries fit together is on the getting there page.
The ride out, and the sea you ride on
The whale sharks feed out in the open sea, north of the island, and the ride takes an hour or more. Marc A. put it at over an hour, and Michael H. at an hour to an hour and a half against the current. Out there you cannot see land or the bottom, and the water is often choppy. The ride back is smoother.
This is the part to plan for. The day is not advised if you get seasick easily, and Tom Z. and a son were both sick on a rough day. If you are prone to it, take something before you board, not once you feel it.
Two at a time in the water
At the feeding area the captain finds the sharks and puts the boat in position. Then two guests and the guide go in together, and you are told when to jump. You wear your life jacket the whole time, with a mask, snorkel and fins. The rules come from SEMARNAT's plan for the whale shark: keep at least 5 m away and never touch.
How long you last beside a shark depends on how you swim. Michael H.'s party got about five minutes in all, while stronger swimmers kept up for longer. When the shark pulls away, the guide calls you back so the next pair can go. Each of you gets two jumps, and they cannot be passed to someone else. The full rules are on the whale shark experience page.
Mantas, dolphins and what else swims past
The whale sharks are why you go, and they are wild, so no day can promise them. The same water often brings more. Mackenzie I. saw manta rays at the site, then turtles and dolphins on the way back. Keep watching the surface on the ride home.
No sunscreen is allowed in the whale shark area. Wear a long-sleeved shirt instead, and a rash guard does the same job in the water. If you want photos, the guide films on a GoPro and you can buy the files at the end. Flash, lights and selfie sticks are banned near the sharks.
Lunch in the shallows off Isla Mujeres
On the way back the boat stops at the north end of the island, in a shallow spot where you can swim while the crew make lunch. For many groups that stop is Playa Norte. Lunch is ceviche and guacamole made on board, with snacks, water and soft drinks through the day. Beer and other alcohol are not in the fare.
Some trips add a short snorkel over a reef on the way in. David P. had one before lunch. Then the boat runs back to the dock, and the driver takes mainland guests back to their hotels. Every whale shark day side by side, shared and private, is on Isla Mujeres whale shark tours.
How the six hours run
- Pickup or the dock. Your Cancún hotel to Punta Sam, or the Black Pearl dock downtown.
- A restroom stop, then aboard. Life jackets on, and a briefing on the rules.
- The ride out. An hour or more on open, often choppy sea.
- Two swims each. Two guests and a guide at a time, beside the sharks.
- The ride back. Smoother, with an eye out for dolphins and turtles.
- Lunch in the shallows. Ceviche and guacamole, and a swim off the north end.
- Back to the dock. Mainland guests ride back to their hotels.
Who this suits: you swim well, cope with a swell and are here in summer
Book this if
You are here between 15 May and 17 September, you swim with confidence in open water, and a long boat ride will not ruin your day. It suits couples, friends and families with older children: Mark P.'s children of 11 and 13 swam, and the listing prices children from four. You need a moderate level of fitness.
Book something else if
You get seasick easily, or you have back or heart trouble, or you are pregnant. Take the three-stop reef and museum trip instead: three hours on calm water close to the island, for $63. If you want the sharks with only your own party aboard, the private whale shark boat runs the same six-hour day.

Meeting at the Black Pearl dock, or at Punta Sam

What travellers say about the whale shark day
★★★★★
The shared whale shark day
Only two people and the guide are in the water at a time, and the better you swim, the longer you keep up with the shark. Life jackets stay on throughout.

★★★☆☆
The shared whale shark day
The crew were kind and found the sharks, but the boat was small and we were thrown about. Both of us were seasick despite taking something.
