Biscayne National Park protects a vibrant marine ecosystem just south of Miami, Florida. Unlike most national parks, 95% of the park is underwater, preserving coral reefs, seagrass beds, mangrove shorelines, and the northernmost Florida Keys islands. Visitors experience the park primarily through boating, snorkeling, diving, and kayaking. Biscayne also protects historic shipwrecks and abundant marine life within the clear turquoise waters of Biscayne Bay.
