About Islas Marías Marine Protected Area

Islas Marías Marine Protected Area
 

The Islas Marías Marine Protected Area surrounds the Islas Marías archipelago, a group of four volcanic islands located approximately 100 kilometers southwest of the Mexican mainland in the state of Nayarit. These islands and their surrounding waters are designated to safeguard fragile marine ecosystems, including coral reefs, mangroves, and underwater volcanic structures. The area supports diverse marine life such as sea turtles, dolphins, various shark species, and abundant fish populations, serving as critical breeding and feeding grounds. Historically, the islands were home to a federal penitentiary, which closed in 2019, enabling increased protection and opportunities to promote conservation and research. Visitors are drawn to the area for activities like snorkeling, scuba diving, wildlife viewing, and ecological study, though access is highly regulated to preserve natural habitats. The Islas Marías also hold cultural value due to their history and indigenous use. Notable landmarks include the Punta Rocosa, known for its underwater biodiversity, and protected nesting beaches for endangered sea turtles. The marine protected area is part of Mexico’s efforts to conserve marine biodiversity and promote sustainable tourism, emphasizing low-impact, guided visits that provide a deeper understanding of this unique island ecosystem. Access is limited to scientific, educational, and authorized tourism activities, supporting the balance between public enjoyment and environmental stewardship.
