When Was Biscayne National Park Established?

Biscayne National Park, a stunning marine paradise located in southern Florida, was officially established on June 28, 1980. However, its journey toward becoming a national park began much earlier, rooted in efforts to preserve the unique marine ecosystems, historical resources, and vibrant natural beauty of the area.

When Was Biscayne National Park Established

Early Preservation Efforts

The origins of Biscayne National Park trace back to the 1960s, a time when local activists and environmentalists voiced concerns over potential industrial development in the area. These developments threatened the delicate coral reefs, mangrove forests, and seagrass beds teeming with marine life.

In response to growing public support for conservation, the federal government designated the area as Biscayne National Monument on October 18, 1968, under President Lyndon B. Johnson. This designation marked a crucial step in protecting the region’s diverse marine habitats and archaeological sites.

From Monument to National Park

Over the next decade, continued advocacy and public interest in broader protection led Congress to expand the boundaries of the monument and elevate its status. On June 28, 1980, Biscayne National Park was officially established, encompassing over 172,000 acres, with 95% of the park located underwater.

A Unique National Treasure

Biscayne National Park is unlike most national parks due to its primarily aquatic landscape. It includes vibrant coral reefs, Biscayne Bay, the northernmost Florida Keys, and parts of the Florida Reef—the only living coral barrier reef in the continental United States. Visitors can explore the park through boating, snorkeling, diving, and wildlife watching, experiencing both natural wonders and historical shipwrecks along the Maritime Heritage Trail.


In summary, Biscayne National Park was officially established on June 28, 1980, evolving from its earlier designation as a national monument in 1968. Today, it stands as a testament to the importance of marine conservation and the beauty of South Florida’s coastal ecosystems.
