Board a private boat from the Riviera Maya and snorkel alongside whale sharks as naturalist guides point out feeding behavior and local conservation efforts. This full-day, eco-focused tour pairs close encounters with practical safety and sustainability practices.
The morning begins before the sun fully warms the shore: an air-conditioned van pulls away from a Riviera Maya hotel, the highway a ribbon of palm shadows, and the Caribbean ahead already flashing promise. By the time the boat slices through the shallow shelf where the Gulf of Mexico meets the Caribbean Sea, the guides—biologists and naturalists—are scanning the glassy blue for the telltale ripple of the largest fish on earth. When a mottled back breaks the surface, the boat eases to a respectful distance and the ocean seems to hold its breath.

Chemical-free sunscreen protects coral and marine life—apply before boarding and reapply as directed.
Operators supply fitted masks and snorkels and sanitize equipment between uses—test the fit before entering the water.
Keep fins horizontal and let the whale shark approach; do not attempt to touch or ride it.
Pickup is typically two hours before departure; plan time for transport and briefings.
