Morning light slices the Pacific as the boat cuts west from Puerto Vallarta, salt spray daring you toward the rounded silhouette of the Marietas Islands. By midmorning the water clarifies to aquamarine and masks slip on for the first snorkel—schools of parrotfish and wrasse inspect every fin stroke while the current nudges you along rocky reefs.

Bring a snug snorkel mask
Boat-provided masks may be basic—your own mask reduces leaks and fog when exploring reefs and caves.
Use reef-safe sunscreen
Protect coral and marine life by choosing mineral-based sunscreen and reapplying sparingly.
