Did you know that the famous Hidden Beach (Playa del Amor) on Islas Marietas was formed by military bomb testing in the early 1900s? This crater-like wonder is now one of Mexico’s most sought-after natural attractions, accessible only by swimming through a water tunnel when tide conditions permit. Located just 32 km (20 miles) northwest of Puerto Vallarta, the Marietas Islands National Park is a UNESCO Biosphere Reserve that offers visitors a unique blend of natural beauty, biodiversity, and adventure.
Getting There & Planning Your Journey
The Marietas Islands are only accessible by boat, with no direct land access available. Most visitors reach the islands through organized tours departing from Puerto Vallarta, Nuevo Vallarta, or Punta Mita. The boat journey takes approximately 1 hour from Puerto Vallarta or just 15 minutes from Punta Mita.
Closest Airports
The nearest airport is Licenciado Gustavo Díaz Ordaz International Airport (PVR) in Puerto Vallarta, which offers direct flights from major cities in the United States, Canada, and Mexico. From the airport, you can reach the marina or tour departure points by taxi or pre-arranged transportation in about 25-40 minutes.

The islands can be visited year-round, but certain seasons offer distinct advantages depending on your interests.
| Season | Months | Weather | Highlights | Notes |
| Peak Season | December-April | 23-30°C (73-86°F), dry | Whale watching, clear waters | Book tours well in advance |

Weather Considerations
The best time to visit for optimal weather conditions is from November to May during the dry season. Water visibility is excellent during these months, making it ideal for snorkeling and diving. If you’re interested in whale watching, plan your visit between December and March when humpback whales migrate to the area to give birth.
