However despite its fame, the Hidden Beach still remains unsullied due to the difficulty of getting to it. Besides being hoisted down from a helicopter, the only known way to access it is though a very small opening on the tidal side of its cavernous walls. This short tunnel, measuring fifty feet with only 6 feet of air space between water and rock, can only be traversed by swimming or, and only during low tide.
The origins of this secluded marvel comes as a surprise. It is said to have been formed in the early 1900′s by the Mexican Government as a bomb site in preparation for the First World War. The Marietawere evidently the government’s target practice site, and these controlled bombings were discovered to have formed several unique caves and rock formations, the most picturesque of which is Playa del Amor.
These known as the “Galapagos of Mexico,” are in themselves an ecological gem. Formed thousands of years ago by a volcanic eruption, the Marieta Islands now house a spectacular array of terrestrial flora and fauna as well as marine species like humpback and manta rays which earned it its title as a UNESCO World Heritage Site. The islands are protected by the government of Mexico, and who intend to enter the reserve must have a permit.
Due to its tropical climate, the Marieta Islands, including the Hidden Beach, enjoy 12 months of sunny days. Nevertheless, it is best to visit the beach during winter months, after the rainy season, when the waters are at their clearest and most beautiful. The best way to see the Marieta Islands would be to book a flight to Puerto Vallarta and then to find a tour operator that will take you to the islands.
