It's the question almost everyone asks before getting in the water: is it safe to swim with whale sharks? The short answer is yes, completely. Despite its imposing size, the whale shark is one of the gentlest marine animals on the planet. Here's why, with facts and the protocols we follow in Holbox.

Are whale sharks dangerous?
No. Although it's the largest fish in the world (it can exceed 12 meters), the whale shark feeds by filtering plankton and tiny fish. It has no teeth to bite large prey and shows no interest in humans. There has never been a recorded attack on a person. It is, literally, a gentle giant.
Facts that put your mind at ease
- It's a filter feeder: it opens its huge mouth to gulp water full of plankton.
- It moves slowly and peacefully.
- It's a protected species and swims are conducted under strict regulation.
- It shares the water with thousands of swimmers in Holbox every summer without incident.

Is there a minimum age? What if I can't swim?
The tour is suitable for most people. For kids we recommend ages ~5 and up who are comfortable in the water; the life vest helps a lot. If you're not a strong swimmer, don't worry: you'll wear a vest and the guide will be by your side the whole time. If you have medical conditions (pregnancy, heart problems), consult your doctor and let us know. Also read our family guide with kids.
What about seasickness?
The only real "risk" for many is seasickness on the boat. If you get queasy easily, take pills 30–60 minutes before and eat a light breakfast. See our what to bring list.
