Head offshore from Marina Vallarta to the Marietas Islands for guided snorkeling, wildlife sightings, and a chance at the famous Hidden Beach (when permits and tides allow). This 4–5 hour day trip balances conservation rules and hands-on guidance for first-time snorkelers.
More ways to explore the area's outdoor wonders
The boat slips away from Marina Vallarta as the city skyline shrinks and the Pacific takes over, salt wind pushing against your face and the hum of an outboard promising open water. Ten minutes out you pass the Ameca River mouth, where dolphins often ride the bow wave, and an hour later the Marietas rise from the blue: compact rocky islets pocked with caves and sheer cliffs where seabirds wheel.

Wildlife
History
Islas Marietas are volcanic remnants that were impacted by mid-20th-century military target practice; conservation campaigns later led to national park protections and restricted access.
Conservation
Strict visitor limits, official permits, and a plastic-free policy aim to protect nesting seabirds and reef habitats; follow guide instructions and don’t touch coral.
