Biscayne National Park protects over 172,000 acres of mostly water and island ecosystems just south of Miami, Florida. Nearly 95% of the park is water-covered, including the northernmost Florida Keys, coral reefs, mangrove shorelines, and the shallow waters of Biscayne Bay. Established in 1980, Biscayne preserves one of the most accessible marine-park ecosystems in the U.S.

Ecology & Marine Habitat
Biscayne combines four ecosystems—open ocean, bay and shoreline, mangrove wetlands, and offshore islands—creating one of North America’s most productive marine refuges. Coral reefs supply food and shelter for juvenile fish and support endangered species like sea turtles and manatees.
History & Conservation
This area was inhabited by Tequesta people for thousands of years. Through Spanish and English colonial eras, it later became a leisure destination in the early 20th century. The park was created in 1980 to protect its fragile marine and island ecosystems near a major urban center.
