Moderate fitness—comfortable swimming ability and mobility on a moving boat are required.
Board a small boat in Puerto Morelos and spend a full day searching for whale sharks along the Mesoamerican Reef, then relax with lunch at Isla Mujeres. This eco-conscious, small-group snorkel tour pairs hands-on guidance with practical logistics.
The engine hums as the shoreline of Puerto Morelos falls away, a bright strip of palms and low buildings shrinking behind you while the open sea spreads ahead. Early light gilds the bay, and the captain scans the horizon with the practiced patience of someone who reads ocean moods. The search for the whale shark — the ocean’s gentle skyscraper — is not a single moment but a rhythm: sweep, spot, approach, and then the hush of bodies slipping into water that tastes of salt and sun.

Port and protected-area entrance fees (~USD 30) are paid in cash at the port — there’s no ATM, so bring exact change.
To protect coral and comply with local conservation practices, wear reef-safe sunscreen and a rashguard.
Take motion-sickness medication before departure if you’re prone to it; the open sea can get choppy.
Guides enforce approach distances to protect the animals — follow instructions for the best and safest viewing.
Puerto Morelos started as a small fishing port and remains a working coastal town that serves as a gateway to the Mesoamerican Reef and nearby islands.
The whale shark corridor is a federally protected area; operators follow no-touch rules and the mandatory fee supports conservation and monitoring programs.
