Biscayne Bay: The Heart of the Park
Biscayne Bay is the main aquatic artery pulsing through the park. Its shallow, sunlit waters are famous for clarity and biodiversity—from lush seagrass beds to vibrant fish populations. Marine birds fly above, while dolphins, stingrays, and sea turtles navigate below. The bay’s circular lagoon is fringed by mangroves, providing shelter for both wildlife and humans seeking peaceful exploration.
Islands of Biscayne: The Keys
The park features a string of islands:
- Elliott Key is the park’s largest island. Formed from ancient coral reefs, it is home to tropical hardwood hammocks and rare plants.
- The islands are vital habitat for endangered cacti and palms, as well as nesting sea turtles.
- Most islands are accessible only by boat, creating uncrowded, pristine settings for exploration.
