Your day on the water

A real ocean safari with the gentle giants

From May to September, whale sharks gather off the coast of Isla Mujeres to feed. They swim near the surface and, as gentle filter feeders, pose no threat, which lets us snorkel next to them safely.

Along the way you may also meet manta rays, sea turtles, dolphins, tropical fish and seabirds in the clear waters of the Mexican Caribbean.

Our local guides have more than 20 years of experience and always put your safety and the wildlife first.

Very important

A true ocean adventure

Whale sharks are wild animals living freely in the open ocean, so every tour is unique. Some days we meet one, dozens or even over a hundred, and on rare occasions none at all. We do not offer refunds or guarantees for sightings because that pressure leads to rule-breaking and stressed animals. We choose to operate responsibly.

Never touch them

Touching whale sharks is not allowed. It is one of the most important rules of this activity.

No sunscreen before swimming

Even reef-friendly sunscreen is not allowed before the swim. Apply it afterwards and bring a long-sleeve UV shirt.

Prone to seasickness?

Take your own medication one or two hours before the tour. We do not provide it on board.

A dream come true! Our guides Nano & Aurturo were fantastic. We were able to swim with the whale sharks, had a separate snorkeling spot that was full of fish, and a stop at Playa Norte with delicious fresh ceviche.

A dream come true! Our guides Nano & Aurturo were fantastic. We were able to swim with the whale sharks, had a separate snorkeling spot that was full of fish, and a stop at Playa Norte with delicious fresh ceviche, guacamole, and Cerveza. We bought the video that the Guide made for 1000 pesos. The day was a huge success highly recommend.

My boyfriend and I did our tour with Bernie and Captain Juan this past week and had an incredible experience. The weather was great and we got two encounters with the whale sharks. They brought great energy to the tour and fully explained the experience and expectations beforehand. I appreciated the video footage of our encounter! I would love to go again with this company!

Bernie and Capt Juan on Nano Shark were amazing! I did the same tour last year with Isla Sea Tours and booked again because of the great experience last year. Capt Juan and Bernie were knowledgeable, made you feel safe in and out of the water and showed us a great time. The whale sharks were incredible to see!

LoLo and Felipe were amazing. Got us all situated, explained how everything would work and got us to a prime spot to go swimming with Whale Sharks all within a couple hours. They took us to Isla Mujeres to go snorkeling around the reef, then to Playa Norte to go hangout in the beautiful turquoise waters and sandbars/ beach. The day wouldn’t have been complete without a little freshly prepared ceviche and guacamole. These guys were great 10/10. If you’re looking for an experience you will never forget while in Mexico check these guys out.

Good to know

Whale Shark Tour FAQ

Are whale sharks dangerous?

No. They are gentle filter feeders, which is why we call them gentle giants. If you respect their space you can feel safe. In almost 20 years of doing this tour we have never had an accident.

When is whale shark season in Isla Mujeres?

The season runs from May 15 to September 17. The best time is usually between mid-June and mid-August. We recommend booking with a few days of flexibility so we can pick the best day for weather and sea conditions.

How many whale sharks will we see?

On a very good day we see between 10 and 100. When we are very lucky we find 200 to 300 in the same area, and the record is about 700 in a single day. Very rarely we do not spot any.

Can I touch the whale sharks?

No. Touching them is not allowed. It is one of the most important regulations of this activity and keeps our impact on the animals as low as possible.

Is seeing a whale shark guaranteed?

No. They are wild animals in the open ocean. We find and swim with them about 98% of the time, but there is no guarantee and no refund if we do not find them. If the port closes because of weather, you get a full refund or can reschedule.

Can I get seasick?

Yes, if you are not used to the motion of the sea. We recommend taking medication one or two hours before the tour. Make sure you are not allergic to it. We do not provide medication on board.

Is sunscreen allowed?

Not before swimming with the whale sharks, even if it is reef-friendly or biodegradable. This rule is regulated by Mexican law. Apply it once the swim is over, and bring a long-sleeve shirt and UV-protective clothing.

Do you offer pickup from Cancun and Riviera Maya?

We can arrange round-trip ground transportation from Cancun, Playa Mujeres, Puerto Morelos and Playa del Carmen for an extra fee. Tell us your hotel when you book and we will give you the best option.

What is your cancellation policy?

You can cancel or change the date of your tour up to 24 hours before departure for a full refund or a date change. Changes or cancellations made less than 24 hours before the tour, and no-shows, are not eligible for a refund. If the port authority does not allow tours because of weather, you can change your date or receive a full refund.
