Whale shark swim in Cancun and Isla Mujeres

Every summer, hundreds of whale sharks gather off Isla Mujeres to feed on plankton. Swimming beside a ten-metre animal that moves without hurry and without threat rearranges your sense of scale. This is snorkelling, not diving: no certification or experience needed.

What makes this dive different

  • Season from mid-May to mid-September
  • Snorkelling activity — no diving skills required
  • Small groups and orderly turns in the water
  • Certified guides and protected-area permits
  • Snorkel gear, water, soft drinks and snacks included

How the day works, step by step

  1. Meeting point. Punta Sam pier, north of Cancun, early morning.
  2. Briefing. Protected area rules, swimmers per turn, minimum distances and what not to do.
  3. Boat ride. Departure to the aggregation zone off Isla Mujeres or Isla Contoy.
  4. In the water. Turns of two swimmers plus a guide. You enter, swim alongside the animal and return to the boat.
  5. Reef snorkel. A reef snorkel stop is often added on the way back.
  6. Return. Back to port. Total duration around 6 hours.

FAQ

Frequently asked questions

Do I need to know how to dive?
No. This is surface snorkelling. Being comfortable in water helps; a life jacket is used and guides stay with you throughout.
Which months have whale sharks?
Mid-May to mid-September, peaking in July and August. Outside the season the animals disperse and the activity is not offered.
Is it safe to swim with a whale shark?
Yes. They are filter feeders and pose no danger to people. The activity is regulated: a limited number of swimmers in the water, a minimum distance and no touching.

“Excellent experience! Rene is a brilliant guide — you can tell he loves what he does and passes on his passion for the sea and marine life at every moment. His instructions and dive plan before every dive make you feel safe and let you enjoy the flora and fauna even more. Highly recommended, I already want to plan new dive trips!”

“I had an excellent experience with Scuba & Adventours Mexico starting my PADI Open Water Diver certification. Everything was explained very clearly and all my questions were answered along the way. Instructor René has a real talent for explaining things simply and clearly.”

“My first time in the diving world! I'm so grateful because my experience with Scuba was incredible — the support and professionalism of René, Delfina and captain Larry make you feel safe at every step. I'll definitely be back with them to certify.”
