Wilderness Landscape & Natural Heritage
Marieta Islands National Park comprises a small group of uninhabited islands located in the Pacific Ocean near the Bahía de Banderas, off the coast of the state of Nayarit, Mexico. The park protects both terrestrial and marine ecosystems, including coral reefs, mangroves, and various species of seabirds and marine wildlife. The islands were once used for military exercises but were declared a national park in 2005 to preserve their unique environment. The islands are famous for their water-filled caves, particularly the Hidden Beach (Playa del Amor), which is accessed through a sea tunnel and is a popular destination for snorkeling, swimming, and birdwatching. The park’s surrounding waters provide habitat for dolphins, humpback whales (seasonal), manta rays, sea turtles, and abundant tropical fish species. Visitors often explore the islands by boat tours departing from Puerto Vallarta or Punta Mita, offering opportunities for kayaking, scuba diving, and wildlife viewing. Regulations strictly limit access to ensure minimal environmental impact, preserving the islands’ fragile ecosystems. The remote and pristine nature of the park supports several protected bird species such as Blue-footed Boobies and Magnificent Frigatebirds. Marieta Islands National Park appeals to those seeking marine adventure, stunning coastal scenery, and ecological study in a protected setting.
