Islas Marías Biosphere Reserve

The reserve spans 641,284 hectares encompassing dry forests, mangroves, coral reefs, and various marine environments off the western coast of Mexico.

The area operated as the Islas Marías Federal Prison from 1905 until 2012, when conservation efforts began transforming it into a protected marine zone.

The Mexican government designated this archipelago as a preservation site, integrating environmental protection with scientific research and educational programs.

Visitors require permits and must follow strict guidelines while participating in activities such as snorkeling, kayaking, and marine wildlife observation.

The reserve houses 54 protected species of land and marine fauna, including 19 endemic species found exclusively within this isolated ecosystem.
