The motor hum drops and the Pacific opens—salt spray stings the face and a ring of jagged volcanic rock appears on the horizon. On this small-boat trip from Puerto Vallarta, the Marietas Islands reveal themselves gradually: a low-lying chain of eroded lava, arches and caves where green water glows and seabirds wheel overhead.
moderate.
3–3.5 hours.
Good cardiovascular fitness and basic swimming ability; able to climb in/out of a small boat and snorkel for short periods.
Access to the interior beach is limited by park rules and tide conditions; tours land where permitted and may require a short swim through a low opening or entry from a dinghy.
Most operators provide snorkel gear and purified water; bringing your own mask improves comfort and fit.
Minimum age on this tour is 12; children must be competent swimmers and carry ID showing age.
Common sightings include tropical reef fish, seabirds like frigatebirds and boobies, and often playful dolphins on the return leg.
The Marietas were once used for military target practice; the resulting caves and blowholes catalyzed later protection and their national park status.
The islands are a protected reserve—follow park rules, avoid touching coral, and use reef-safe products to minimize impact.
