The boat slips out of Puerto Vallarta and the bay opens like a living map—blue and restless, the water daring you forward. Salt wind carries the day’s promise: a first cup of coffee, a watchful eye for dorsal fins, and the blurred silhouette of the Marietas rising from the horizon. On approach the islands feel compact and muscular, rock faces carved by tides that still push and probe at their edges.

History
The Marietas were historically used by local fishermen and later designated a national park to protect nesting seabirds and reefs; military exercises on the islands in the 20th century led to restricted access until conservation efforts increased.
Conservation
Visitor numbers and landing sites are regulated to protect nesting seabirds and fragile coral; choose operators that follow park rules and use reef-safe products to minimize impact.

Pick-morning departures
Morning trips often have calmer seas and better visibility for snorkeling; aim to board early for smoother water and more marine life activity.
Use reef-safe sunscreen
Protect coral and marine life—apply biodegradable sunscreen before boarding and reapply after swimming as needed.
Prevent seasickness
If you’re prone to motion sickness, take medication or use acupressure bands before departure and sit mid-ship for the steadiest ride.
Secure personal items
Bring a small dry bag and leave valuables ashore or locked—boats get wet and phones can slip during boarding and reef activities.
Reef-safe sunscreen
Protects skin and the marine environment during prolonged sun exposure on deck and while snorkeling.
