The boat cuts a clean path through Caribbean blue as the mainland recedes and a low strip of green rises on the horizon: Contoy. By mid-morning the ocean has settled into a glassy sheet and the guides scan the surface, eyes practiced for the subtle backwash that marks a whale shark. When the first pale flank breaks the water you feel the scale of it—this is not a fleeting glimpse but a patient, almost languid presence, moving with a slow appetite for plankton.

Adventure Tips
Book the season
Whale shark encounters are seasonal—plan between May and September for the best odds and book early to secure pickup from Cancún or Playa del Carmen.
Bring reef-safe sunscreen
Use only reef-safe sunscreen to protect corals; apply before boarding to avoid cloudy water.
Use a buddy system
Swim in short shifts and always enter and exit the water under guide supervision to avoid crowding the animal.
Pack for a full day
Bring a towel, dry bag for your phone, a light change of clothes and any motion-sickness remedies—boat time can be up to 1–1.5 hours each way.
