Whale sharks are large, dark with spots, and spend almost all their time close to the surface.

When it’s ready to swim, you’ll enter the water as instructed without splashing. It’s easy to get distracted by seeing such incredible creatures for the time, but make sure you pay attention to the guide.

It’s normal to take two people into the water at a time to swim with the sharks. 

Whale sharks move constantly, and you’ll swim alongside them while the boat follows at a suitable distance. Make sure you follow the “no touching” rule.

Your guide will swap people on and off the boat so everyone gets a turn. Typically you’ll get two or three turns each for several minutes or more.

After you’ve enjoyed swimming with the sharks, you might have lunch as the boat returns to Cancun or head to one of the islands.
